Guest Posts: Preparing for Mayo v. Prometheus Labs

By Professor John Golden, Professor in Law, The University of Texas at Austin

Mayo Collaborative Services v. Prometheus Laboratories, Inc., No. 10-1150 (S. Ct.)

Scheduled for oral argument on Wednesday, December 7, 2011

In Mayo Collaborative Services v. Prometheus Laboratories, Inc., the U.S. Supreme Court looks to address questions of whether and when certain types of medical methods are patentable subject matter. Prometheus specifically involves methods for optimizing patient treatment in which the level of a drug metabolite is measured and a measured level above or below a recited amount "indicates a need" to decrease or increase dosage levels. In 2005, the Court granted certiorari on related issues in Laboratory Corp. of America v. Metabolite Laboratories, Inc., but the Court later dismissed LabCorp as improvidently granted. In 2010, the Court reaffirmed the existence of meaningful limitations on patentable subject matter in Bilski v. Kappos, but the Court but did little to clarify the scope of those limitations.

Will Prometheus bring light where Bilski failed? Arguments to the Court invite it to further clarify the status of the machine-or-transformation test for process claims. Bilski indicated that this test is relevant but not necessarily decisive, and the Federal Circuit relied heavily on the test in upholding the subject-matter eligibility of Prometheus's claims. In the circuit's view, "asserted claims are in effect claims to methods of treatment, which are always transformative when one of a defined group of drugs is administered to the body to ameliorate the effects of an undesired condition." Likewise, a metabolite-level measurement step was found to "necessarily involv[e] a transformation." Although Prometheus's claims include "mental steps," the circuit emphasized that the inclusion of such steps "does not, by itself, negate the transformative nature of prior steps."

Prior posts provide additional background on the Prometheus case. The first wave of merits briefs have been filed. These include the opening brief for the petitioners, briefs in support of the petitioners, and briefs in support of neither party. The respondent-patentee's brief as well as supporting amicus briefs will be due in the upcoming weeks.

BRIEF FOR PETITIONERS (Stephen Shapiro, Mayer Brown): Prometheus's patent claims violate Supreme Court precedent forbidding claims that "preemp[t] all practical use of an abstract idea, natural phenomenon, or mathematical formula." Prometheus's claims "recite a natural phenomenon—the biological correlation between metabolite levels and health—without describing what is to be done with that phenomenon beyond considering whether a dosage adjustment may be necessary." The claims' drug-administration and metabolite-measurement steps are merely "'token' and 'conventional' data-gathering steps" that cannot establish subject-matter eligibility. Patent protection is unnecessary to promote the development of diagnostic methods like those claimed and will in fact interfere with both their development and actual medical practice.

AMICUS BRIEFS SUPPORTING PETITIONERS

AARP & PUBLIC PATENT FOUNDATION (Daniel Ravicher, Public Patent & Cardozo School of Law): "Allowing patents on pure medical correlations … threatens doctors with claims of patent infringement" and "burdens the public with excessive health care costs, and dulls incentives for real innovation." "The Federal Circuit has latched on to trivial steps beyond mental processes, such as the 'administering' step in this case, to uphold patents that effectively preempt all uses of laws of nature." Prometheus's recitation of an "administering" step stands "in stark contrast to most pharmaceutical patents that require a 'therapeutically effective amount' of a drug be administered."

ACLU (Sandra Park, ACLU): In assessing subject matter eligibility, the Supreme Court "has focused on the essence of the claim," using a "pragmatic approach [that] allows the Court to see through clever drafting." Prometheus's insertion of drug-administration and/or measurement steps into a claim "does not alter the fact that the essence of the claim is the correlation between thiopurine drugs and metabolite levels in the blood." Further, the First Amendment bars Prometheus's claims. "What Prometheus seeks to monopolize … is the right to think about the correlation between thiopurine drugs and metabolite levels, and the therapeutic consequences of that correlation."

AMERICAN COLLEGE OF MEDICAL GENETICS ET AL. (Katherine Strandburg, NYU School of Law): The patents at issue "grant exclusive rights over the mere observation of natural, statistical correlations." They "convert routine, sound medical practice into prohibited infringement" and generate burdens and conflicts for patient care and follow-on innovation. "The machine or transformation test is inapposite … to determining whether a claim preempts a natural phenomenon." It can be too trivially satisfied without shedding sufficient light on whether claims "reflect inventive activity" or "improperly preempt downstream uses of the phenomenon."

ARUP & LABCORP (Kathleen Sullivan, Quinn Emanuel): "The patents assert exclusive rights over the process of administering a drug and observing the results…. This not only blocks the mental work of doctors advising patients, but also impedes the progress of research by seeking to own a basic law of nature concerning the human body's reaction to drugs." "Patents on measurements of nature" raise constitutional concerns by removing factual information from the public domain, thereby conflicting with patents' constitutional purpose to "promote the Progress of Science and useful Arts" and threatening to chill "scientific and commercial publication."

CATO INSTITUTE ET AL. (Ilya Shapiro, Cato Institute): This case provides the Supreme Court with an opportunity to strike a blow against the "thousands of abstract process patents which have been improvidently granted since the 1990s" and that are already adversely affecting software and financial innovation. Historically, patentable "processes" "aimed to produce an effect on matter, and these patents do not." The "indicat[ing] a need" clauses in Prometheus's claims do not even form part of a process because they do "not describe an action." Patent claims such as these, "whose final step is mental," impermissibly tread on the public domain and "freedom of thought."

NINE LAW PROFESSORS (Joshua Sarnoff, DePaul College of Law): The Supreme Court "should expressly recognize" that the Constitution requires that "laws of nature, physical phenomena, and abstract ideas" be treated as prior art for purposes of determining patentability. "Allowing patents for uncreative applications would effectively provide exclusive rights in and impermissibly reward the ineligible discovery itself." Barring claims like Prometheus's under section 101, as opposed to relying on patentability requirements such as novelty and nonobviousness, promotes "efficient gate-keeping" and "sends important signals."

VERIZON & HP (Michael Kellogg, Kellogg Huber): "It is longstanding law that a claim is non-patentable if it recites a prior art process and adds only the mental recognition of a newly discovered property of that process." See Gen. Elec. Co. v. Jewel Incandescent Lamp Co., 326 U.S. 242 (1945). "This principle is soundly based on Section 101's limitation to processes and products that are not only 'useful' but 'new.'" "[A]dding to the old process in Prometheus's patent claims nothing more than a mental step of recognizing the possible health (toxicity or efficacy) significance of the result of the process does not define a 'new and useful process.'"

AMICUS BRIEFS SUPPORTING NEITHER PARTY

UNITED STATES (Solicitor General Donald Verrilli, Jr.): The claimed methods recite "patent-eligible subject matter," and petitioners' objections to patentability are properly understood as challenges to the claimed methods' novelty and nonobviousness. By analogy with "patent law's 'printed matter' doctrine," the claims should ultimately be found invalid because, as construed by the district court, they "merely … appen[d] a purely mental step or inference to a process that is otherwise known in (or obvious in light of) the prior art." But the Supreme Court should affirm the Federal Circuit's holding on subject matter eligibility.

AIPPI (Peter Schechter, Edwards Wildman): AIPPI "encourages all member countries to allow medical personnel the freedom to provide medical treatment of patients without the authorization of any patentee." Unlike the U.S. and Australia, most countries "exclud[e] methods of medical treatment of patients from patent eligibility." When the medical-practitioner exemption of 35 U.S.C. § 287(c)(1) applies, "the courts lack subject matter jurisdiction." The exemption applies to the defendants, who "are plainly 'related health care entities.'" Thus, "the case should be dismissed for lack of federal subject matter jurisdiction."

MICROSOFT (Matthew McGill, Gibson Dunn): Subject-matter eligibility tests should not involve "pars[ing] the claimed invention into the 'underlying invention' and those aspects that are 'conventional' or 'obvious' or insignificant 'extra- or post-solution activity.'" Such parsing lacks any guiding principle that can make its application predictable. Petitioners seek an improperly "expansive application of the mental steps doctrine." "[I]f every step of a process claim can be performed in the human mind, that process is unpatentable." But the Federal Circuit has improperly "extended th[is] principle to apply to machines or manufactures that replicate mental steps."

NYIPLA (Ronald Daignault, Robins Kaplan): Innovation's "bewildering pace" argues against "rigid categorization of patent-eligible subject matter." "[T]here is no basis for excluding processes directed to analyzing the chemicals in a patient's body from patent eligibility." When satisfied, the machine-or-transformation test should decisively establish eligibility. But failure of the test should not necessarily establish ineligibility. Preemption analysis "must incorporate a critical assessment of whether the claim at issue actually claims a fundamental principle as a fundamental principle in contrast to an application of that principle."

ROCHE & ABBOTT (Seth Waxman, WilmerHale): Patents are crucial for innovation in personalized medicine and more particularly for the continued development diagnostic tests that can enable such medicine's practice. Arguments "that patents on diagnostic tests stifle innovation and basic scientific research" are "largely based on speculation, rather than sound evidence." Generally speaking, "market-driven business practices and self-enforcing market norms correct for any perceived limitations on the accessibility of patented diagnostic technologies." Congress should be trusted to provide appropriate patent-law exemptions for medical practice and research.

Pending Supreme Court and en banc Federal Circuit Patent Cases

By Jason Rantanen

The Supeme Court continues to take an active interest in patent cases, with three currently pending before the Court.  Briefs are available through the American Bar Association's Supreme Court coverage site.

Patent Cases Pending Before the Supreme Court:

Mayo v. Prometheus: Subject Matter Patentability of Processes, redux. In Mayo, the Supreme Court will revisit the issue of patentable processes in a case that was the subject of a grant-vacate-remand order following Bilski.  The Court has asked the parties to answer the following question:

Whether 35 U.S.C. § 101 is satisfied by a patent claim that covers observed correlations between blood test results and patient health, so that the claim effectively preempts all uses of the naturally occurring correlations, simply because well-known methods used to administer prescription drugs and test blood may involve “transformations” of body chemistry.  

Argument is set for December 7, 2011.  This case has prompted substantial debate and numerous amici submissions.  Prior PatentlyO posts:

Reverse Payment Settlements Return to the Supreme Court

Louisiana Wholesale Drug Co. v. Bayer AG (On Petition for a Writ of Certiorari 2011)

Ordinarily, a patent is valuable when it offers some degree of market exclusivity. Over the past decade, we have seen a number of examples where a patent holder felt it necessary to take some additional steps to secure a term of exclusivity – namely paying would-be competitors to (1) not enter the market; (2) not challenge the patent's validity, enforceability, or scope; and/or (3) delay market entry. This situation most often emerges in the pharmaceutical market between innovator companies and generic manufacturers. In several cases, the innovator company (patentee) has paid a generic challenger to give up or delay market entry. This situation is often termed a "reverse payment settlement" because the settlement payment flows in the opposite direction of what we ordinarily expect in patent litigation. (Ordinarily, to settle a patent case, an accused infringer pays a dollar amount to the patentee. In these cases, the patentee is paying a dollar amount to the accused infringer). Intricacies of the Hatch-Waxman Act provides some incentive for the reverse payment settlements. See, Christopher Holman, Do Reverse Payment Settlements Violate the Antitrust Laws?, 23 Santa Clara Computer and High Technology L.J. 489 (2007).

In this case, reverse payment settlements are being challenged as unlawful under the Sherman Act. Although paying a competitor not-to-compete would normally be seen as an antitrust violation, patentee's argue that reverse settlements are per se lawful's so long as they are closely related to the exclusionary potential of the patent.

The question now presented to the Supreme Court is:

Whether an agreement by a patent owner to pay a potential competitor not to enter the market is legal per se, as the Second and Federal Circuits have held, to be treated under the rule of reason, as the Eleventh Circuit has held, or illegal per se, as the Sixth Circuit has held?

In a friend-of-the-court brief filed by Stanford Prof. Mark Lemley, a group of 80+ professors argue that the Supreme Court should certainly hear the case and that the 2nd Circuit rule of per se legality is wrong. The professors write:

This rule [of per se legality] is based on the mistaken premise that (absent a fraudulent procurement) a patent grants full immunity from antitrust scrutiny for any and all anti-competitive effects within the exclusionary power of the patent.

A large group of state attorneys general also filed a friend-of-the-court brief arguing that a "surge in reverse payment agreements is threatening the existence of generic competition and the availability of affordable drugs to the states and their citizens."

Supreme Court Does not Decide Costco v. Omega Int'l Exhaustion Case

Costco v. Omega (Supreme Court 2010)

In Costco, the Supreme Court was asked to apply the first sale doctrine of copyright law in the context of international sales. Costco had purchased legitimate Omega watches abroad and then imported them into the US.  The watches included a small copyrighted design on the back surface and Omega argued that the importation and further distribution of the watches constituted copyright infringement.  Ordinarily, the purchaser of a legitimate copy of a work can lawfully resell the copy based on the first sale doctrine (also known as copyright exhaustion). The trick, however, is that copyright is territorial in nature and the first sale abroad arguably did not “exhaust” the US copyright. The 9^th  Circuit had sided with Omega — holding that the first sale doctrine did not apply to foreign manufactured copies that were purchased abroad.

Without opinion, and in a 4–4 split, the Supreme Court has affirmed the 9^th  Circuit decision. However, because of the 4–4 split, the case will not be seen as precedent-setting. Thus, as Ryan Vacca wrote in an e-mail this morning: “Our unanswered questions . . . remain unanswered.”

 

Global-Tech v. SEB: Petitioner's Merits Brief

By Jason Rantanen

On Monday, Petitioner Global-Tech filed its brief in the inducement of infringement case pending before the Supreme Court.  The complete brief can be downloaded from the American Bar Association's website.  The arguments are summarized below:

35 U.S.C. 271(b) Requires the State of Mind of "Purposeful, Culpable Expression and Conduct" to Encourage an Infringement.

Global-Tech takes the position that inducement of patent infringement under 271(b) requires "'purposeful, culpable expression and conduct' to encourage an infringement."  In other words, the accused party must possess the "purpose" of causing the infringement of a patent - even knowledge of infringement is insufficient.  In support of this position, Global-Tech relies heavily on MGM Studies, Inc. v. Grokster, Ltd., 545 U.S. 913 (2005), a copyright inducement case in which the Court discussed 271(b) and described the inducement rule as premising liability on "purposeful, culpable expression and conduct."  Global-Tech buttresses its argument by asserting that a lower standard would make 271(b) so broad as to render 271(c) (contributory infringement) insignificant and, furthermore, is supported by the legislative history.

Global-Tech also raises two policy considerations.  First, it delves into the issue of causation, suggesting that because 271(b) does not contain a causation requirement, Congress must have intended to for it to apply only to "morally culpable conduct" - which Global-Tech equates with purpose.  Second, it argues that (absent clear Congressional intent) there is a presumption that statutes are meant to only regulate conduct outside the United States to the extent necessary to further important U.S. interests, and that anything less than a "purposeful, culpable expression and conduct" standard is unnecessary to further U.S. interests. 

The "Deliberate Indifference" Standard is Wrong

In addition to advancing its "purposeful, culpable expression and conduct" approach to inducement, Global-Tech also argues that the Federal Circuit's "deliberate indifference to a known risk" standard is lower than knowledge, recklessness, and even negligence.  Global-Tech rests this assertion on the proposition that because the Federal Circuit's articulation of the "deliberate indifference" standard did not specify the degree of risk, it thus encompasses even minimal risks of infringement.  Global-Tech further argues that the risk in this case was of the minimal variety because it did not know about the patent and because of the uncertainties of both claim construction and infringement proceedings.

Global-Tech raises two additional arguments.  After asserting that aiding and abetting, a related tort doctrine, requires knowledge of the actor's participation in an underlying crime or tort, it then contends that the use of "actively," "induces," and "infringement" in 271(b) signals that the standard must be higher than that of aiding and abetting (i.e.: purpose).  From a policy standpoint, Global-Tech criticizes the "deliberate indifference" standard as being quite unclear - and thus placing a burden on competition and innovation.

Global-Tech concludes by asserting that if the Court holds that 271(b) requires not just purposeful, culpable conduct or knowledge, but also recklessness, it should reverse and remand.

An Objective View of Fault in Patent Infringement

By Jason Rantanen

In GlobalTech v. SEB, the Supreme Court is addressing the question "[w]hether the legal standard for the state of mind element of a claim for actively inducing infringement under 35 U.S.C. § 271(b) is "deliberate indifference of a known risk" that an infringement may occur...or instead "purposeful, culpable expression and conduct" to encourage an infringement.”  Yet, as I suggested last month, perhaps framing the issue as an involving an inquiry into the subjective state of mind of an accused inducer isn't the best approach.  Instead, I propose that an analysis akin to civil recklessness - asking whether a high risk of infringement of a valid patent would have been obvious to a reasonable person in the accused party's position - is the better way to view the fault component of indirect infringement.  

That's the central argument of a draft article that I've prepared, and I'm interested in any feedback readers might have.  The abstract is provided below; the complete paper is available here. 

Unlike direct patent infringement (a strict liability claim), indirect and willful infringement require the patent holder to demonstrate fault on the part of the accused infringer. The conventional approach to the fault elements of these doctrines views them as involving a subjective inquiry into the accused party’s state of mind. Inducement of infringement, for example, requires that the alleged infringer possess mental culpability for it to be found liable. The question presented by the Supreme Court’s recent grant of certiorari in Global-Tech v. SEB is the quintessential illustration of this conventional view, asking whether the “state of mind” of the accused party is one of “deliberate indifference” or “purpose.” This mens rea-based approach to fault is likely the product of indirect infringement’s origins as an adaptation of the tort theory of aiding and abetting, an intentional tort.

This paper asserts that this conventional view of fault for indirect infringement is inherently flawed, and is largely nonsensical in the modern context in which indirect infringement is assessed. In large part this is because fault in patent infringement, unlike the tort tradition in which it was developed, involves assessment of particular legal – as opposed to factual – consequences, consequences that are both rarely certain and unlikely to ever be desired.

Rather than continuing to view the fault elements of these doctrines as if they were traditional intentional torts, this paper proposes that the law should instead apply an objective test more closely tailored to the specific context in which patent infringement arises. Specifically, it suggests that a better approach is to conceive of the fault element as requiring an objective inquiry into whether a high risk of patent infringement would have been obvious to another in the accused party’s position. In addition to providing a more accurate and usable articulation of the fault element, viewing the question in terms of risk enables finer tuning of the doctrine when seeking optimal deterrence effects. Furthermore, this change would parallel recent shifts in the approach to fault in the context of willful infringement, and would be consistent with the actual normative standard being applied by courts.

 

Supreme Court to Decide Microsoft Patent Case that Could Make it Easier to Invalidate Patents

By Dennis Crouch

Microsoft Corp. v. i4i Ltd. (Supreme Court 2010)

The Supreme Court has granted Microsoft's petition for a writ of certiorari and will consider whether patent law requires clear and convincing evidence of invalidity in order to invalidate an issued patent. Microsoft asks that the standard be lowered – at least for the situation where the evidence of invalidity was not considered by the patent office before the patent issued. The Supreme Court has not directly ruled on the issue. However, in KSR v. Teleflex, the Supreme Court did note that the "the rationale underlying the presumption — that the PTO, in its expertise, has approved the claim — seems much diminished" in cases where the patentee "fail[ed] to disclose" the key prior art to the PTO.

I expect that the court will agree that the statutory presumption of validity does not require a clear and convincing standard and that the standard should be lowered when a court is presented with evidence that is substantially different from that considered by the USPTO. Without explanation, Chief Justice Roberts has recused himself from this case – leaving eight justices to decide. At this point, I expect that all members of the court will agree that the standard should be lowered with some disagreement on the exact rule.

Clear and Convincing Evidence: Felony criminal cases require that prosecutors prove their case beyond a reasonable doubt. Most civil cases only require a preponderance of the evidence – often referred to as "more likely than not." Thus, in patent infringement cases, the patentee need only prove that it is more likely than not that the defendant infringed. However, the Federal Circuit has long required that invalidity defenses be proven with clear and convincing evidence. The clear and convincing standard is somewhere between a preponderance of the evidence and beyond a reasonable doubt and is sometimes referred to as "substantially more likely than not." Microsoft has not directly challenged the CAFC's rule of corroborative evidence that a single person's testimony is never sufficient to invalidate a patent.

i4i's case: In 2009, an Eastern District of Texas jury awarded $200 million + interest to i4i after finding that Microsoft willfully infringed the Canadian company's patent. Judge Davis subsequently added-on $40 million for willful infringement. The judge also issued an injunction ordering Microsoft to stop selling Word Products with the capability of using "custom XML." That injunction was stayed by the Federal Circuit pending appeal. On appeal, the Federal Circuit affirmed the lower court's findings of validity, willful infringement, enhanced damages, and permanent injunctive relief. In the meantime, the USPTO has concluded its reexamination of the i4i patent — confirming that the claims at issue are patentable. Microsoft filed a second reexamination request in August 2010 (shortly after it filed its petition to the Supreme Court). However, on November 24, 2010, the USPTO denied the request to begin a new reexamination – finding that the newly asserted prior art failed to raise a substantial new question of patentability (SNQ) as required by statute. Microsoft will likely appeal that denial. In addition, Microsoft apparently patched its software to prevent someone from using custom XML in Word in an effort to avoid the injunction and any further damages.

Microsoft has now moved-on to the Supreme Court — asking the high court to reject the "clear and convincing" evidence standard for proving a patent invalid. As Microsoft wrote in its petition for writ of certiorari, the question is "Whether the court of appeals erred in holding that Microsoft's invalidity defense must be proved by clear and convincing evidence" when the prior-art was not considered by the USPTO. This is essentially the same question that Microsoft raised in its 2008 petition in z4. That petition was withdrawn after the parties settled.

The Patent: i4i's asserted patent (U.S. Patent No. 5,787,449) covers a system for editing the metacodes of an HTML or XML document. The system uses a metacode map that is stored separately from the XML document and provides a menu of potential metacodes. The patent application was filed in 1994 and should remain in-force until 2015.

Microsoft's Invalidity Argument: Microsoft was not able to uncover any prior publication or patent that would invalidate the invention. However, the software giant argued at trial that i4i had sold an embodiment of the invention in the US more than one year prior to the 1994 patent application date. In particular, Microsoft argues that the invention was "embedded in a system called S4 - that the inventors of the ′449 Patent developed and sold to SEMI, a client of i4i's predecessor, over a year before applying for the ′449 Patent." That sale was not disclosed to the USPTO during the original prosecution and could not be presented during reexamination because reexaminations are limited to a review of prior art patents and publications. At the trial, the inventors (Vulpe and Owens) testified that the S4 system did not include a metacode map or separate the map from the marked-up document – two key features of their invention. Because the source-code for the 1993 custom software was no longer available, Microsoft primarily relied on testimony from a former i4i employee and upon written statements that Vulpe had made to investors and to the Canadian Government suggesting that the S4 software did separate metacode information.

The jury form asked "Did Microsoft prove by clear and convincing evidence that any of the listed claims of the '449 patent are invalid?" The jury answered "no." On appeal, the Federal Circuit held that the jury had sufficient evidence to rule that the patent was not anticipated by S4.

Importance of the Rule: A recent study conducted by Etan Chatlynne and published on Patently-O looked at all 119 Federal Circuit decisions on patent validity for the past several years. The study found that lowering the burden of proof would not have made any difference for 74% of those cases but might have made a difference in 26% of the cases. None of the decisions expressly stated that the result would be different if the standard had been reduced.

The clear and convincing standard probably has an important psychological impact in jury (and judicial) deliberations where the defendant's high burden for proving invalidity is contrasted with the plaintiff's lower burden for proving infringement.

Supreme Court to Hear Case on Inducing Patent Infringement

Global-Tech Appliances, Inc. v. SEB S.A. (Supreme Court 2010)

The Supreme Court has granted writ of certiorari in the case of Global-Tech v. SEB to decide the level of intent required for inducing infringement. The question raised is: Whether the legal standard for the "state of mind" element of a claim for actively inducing infringement under 35 U.S.C. § 271(b) is "deliberate indifference of a known risk" that an infringement may occur or instead "purposeful, culpable expression and conduct" to encourage an infringement.

Section 271(b) of the patent act creates a cause of action against inducing infringement. The statute reads "Whoever actively induces infringement of a patent shall be liable as an infringer." Courts have struggled for years to define the level of intent that is sufficient to satisfy the rough statutory guidelines.

In DSU Medical Corp. v. JMS Co., Ltd., 471 F.3d 1293 (Fed. Cir. 2006) (en banc), the Federal Circuit held that inducement charges could only be sustained if the accused inducer "knew of the patent." In SEB (T-Fal) v. Montgomery Ward & Co., 594 F.3d 1360 (Fed. Cir. 2010), the Federal Circuit eased-back on that requirement by holding that "deliberate indifference" to potential patent rights could be sufficient to satisfy the knowledge requirement of inducement charges. Thus, Judge Rader wrote in SEB that "a claim for inducement is viable even where the patentee has not produced direct evidence that the accused infringer actually knew of the patent-in-suit."

In the case, Judge Rader distinguished between the subjective determination of "deliberate indifference" and an objective "should-have-known" standard. An interesting aspect of the Federal Circuit decision is the court's use of non-patent and non-Federal Circuit cases to aid its interpretation of the law. Specifically, the decision relies on three cases that are decidedly non-patent: Farmer v. Brennan, 511 U.S. 825 (1994); United States v. Carani, 492 F.3d 867, 873 (7th Cir. 2007); and Woodman v. WWOR-TV, Inc., 411 F.3d 69 (2d Cir. 2005).

Farmer v. Brennan involved the question of whether an incarcerated pre-operative transsexual who projects female characteristics could be held in a men-only prison. The Supreme Court there held that a prison official could be liable for "deliberate indifference" to inmate safety. US v. Carani involved an appeal of a child pornography conviction and the Seventh Circuit ruled that the defendant's knowledge of the child-status of the pornography was satisfied by the defendant's deliberate avoidance of or indifference to the truth. Woodman v. WWOR-TV involved an age discrimination charge against FOX and noted that knowledge of a fact may be proven through evidence that the party "consciously avoided knowledge of what would otherwise have been obvious him."

The cases cited above are not found in the appellate briefs. Rather, the SEB court's concept of "deliberate indifference" was raised sua sponte by the Federal Circuit.

The petition for certiorari was aided by a short but compelling brief by the legal academics led by Professor Lemley (Stanford) and Holbrook (Emory) and also signed by conservatives such as Richard Epstein (Chicago). The brief basically argued that the Federal Circuit has been unable to clarify its own law on the state of mind requirement for inducement liability. The brief also suggest that the Federal Circuit SEB decision conflicts with the Supreme Court's precedent in MGM Studios, Inc. v. Grokster, Ltd., 545 U.S. 913, 936 (2005).

Microsoft (Again) Asks Supreme Court to Lower Clear and Convincing Standard

Microsoft Corp. v. I4I Limited Partnership (on petition for writ of certiorari 2010)

In 2009, an Eastern District of Texas jury awarded $200 million + interest to i4i after finding that Microsoft willfully infringed the Canadian company’s patent. Judge Davis subsequently added-on $40 million for willful infringement.  The judge also issued an injunction ordering Microsoft to stop selling Word Products with the capability of using “custom XML.” That injunction was stayed by the Federal Circuit pending appeal.  On appeal, the Federal Circuit affirmed the lower court’s findings of validity, willful infringement, enhanced damages, and permanent injunctive relief. In the meantime, the USPTO has concluded its reexamination of the i4i patent — confirming that the claims at issue are patentable. In addition, Microsoft apparently patched its software to prevent someone from using custom XML in Word.

Microsoft has now moved-on to the Supreme Court — asking the high court to reject the “clear and convincing” evidence standard for proving a patent invalid. As Microsoft writes in its petition for writ of certiorari, the question is “Whether the court of appeals erred in holding that Microsoft’s invalidity defense must be proved by clear and convincing evidence” even when the prior-art was not considered by the USPTO. This is essentially the same question that Microsoft raised in its 2008 petition in z4. That petition was withdrawn after the parties settled.

The patent statute (35 U.S.C. § 282) indicates that an issued patent is “presumed valid” and that the “burden of establishing invalidity” rests with the party asserting invalidity. The Federal Circuit has held that the presumption of validity is properly realized by a clear and convincing standard.  The Supreme Court has not directly ruled on the issue. However, in KSR v. Teleflex, the Supreme Court did note that the “the rationale underlying the presumption — that the PTO, in its expertise, has approved the claim — seems much diminished” in cases where the patentee “fail[ed] to disclose” the key prior art to the PTO.

Patents that Exhibit "Potential Vagueness and Suspect Validity"

In eBay v. MercExchange (2006), the Supreme Court ruled that an adjudged infringer should only suffer permanent injunctive relief once the traditional four-factor test of equity had been satisfied. This general priciple was recently supported by the non-patent Supreme Court case of Monsanto v. Geertson (2010). In Monsanto, the court wrote “An injunction is a drastic and extraordinary remedy, which should not be granted as a matter of a course.” The court’s apparent patent-law-centrist, Justice Kennedy, wrote a concurring opinion suggesting that times-have-changed and that courts may have good reason to frequently deny injunctive relief. With some flair, Justice Kennedy suggested that the “potential vagueness and suspect validity of some … patents may affect the calculus under the four-factor test.”

In many respects, Justice Kennedy’s statement from eBay seems odd. The issue of permanent injunctive relief only arises after trial — after the patents are deemed valid and infringed. The trial is intended to remove any question regarding potential invalidity of the patent rights. However, in a recent amicus brief to the Federal Circuit, Verizon attempts to provide some explanation and some teeth to Kennedy’s proposal. (Justice Kennedy’s statement has been quoted and discussed in over 80 law review articles over the past four years.)

The Verizon brief was filed in the pending en banc case of TiVo v. EchoStar. That case focuses on whether the infringement of new products introduced by an adjudged infringer should be analyzed through contempt proceedings or through a new trial.

Verizon’s brief does not focus on the questions at issue in TiVo, but rather addresses the broader question of whether injunctive relief should be issued in-the-first-place. Expanding on Justice Kennedy’s statements, Verizon argues that — even after a patent is determined valid at trial — the court must consider the possibility that the patent is invalid as part of the injunction analysis:

The need to ensure that equity “mould[s] each decree to the necessities of the particular case,” Hecht, 321 U.S. at 329, requires that a district court take into account the possibility that a patent – issued and adjudged to be valid in the context of an infringement trial – is, in fact, invalid.

To explain its position, Verizon points to a specific (and common) situation — where the infringed patent is pending reexamination at the USPTO. The brief states boldly that “the pendency of a PTO reexamination proceeding weighs strongly against imposition or continuation of an injunction.”

Explaining Patentable Subject Matter: The First Bilski Test Cases

RESEARCH CORPORATION TECHNOLOGIES v. MICROSOFT (Fed. Cir. 2010)

One of the first cases that may address the Supreme Court's ruling in Bilski v. Kappos involves RCT's claimed method of halftoning color images. The district court held the asserted claims invalid for failing to satisfy Section 101 of the patent act. The following two claims are representative:

1. A method for the halftoning of gray scale images by utilizing a pixel-by-pixel comparison of the image against a blue noise mask in which the blue noise mask is comprised of a random non-deterministic, non-white noise single valued function which is designed to produce visually pleasing dot profiles when thresholded at any level of said gray scale images.

11. A method for the halftoning of color images, comprising the steps of utilizing, in turn, a pixel-by-pixel comparison of each of the plurality of color planes of said color image against a blue noise mask in which the blue noise mask is comprised of a random non-deterministic, non-white noise single valued function which is designed to provide visually pleasing dot profiles when thresholded at any level of said color images, wherein a plurality of blue noise masks are separately utilized to perform said pixel-by-pixel comparison and in which at least one of said blue noise masks is independent and uncorrected with the other blue noise masks.

Microsoft argues that the inventive portion of the claims are directed to the unpatentable mathematical operation of halftoning and the remaining portions use well known technology to preempt use of the mathematical operation.

IN RE BONNSTETTER (Fed. Cir. 2010)

A second pending Section 101 case involves Bonstetter's claimed "method of benchmarking a job." The specification reports that the invention can be implemented "using pencil and paper" and the claim involves a simple four step process:

Claim 1. A method of benchmarking a job comprising:
identifying subject matter experts (SMEs) for the job;
facilitating discussion with the SMEs to identify and prioritize key accountabilities of the job;
giving a survey to SMEs to determine soft skills necessary for superior performance in the job, the survey incorporating the key accountabilities;
combining responses to the survey from multiple subject matter experts into a composite report identifying and prioritizing skills for superior performance for the job; and
interviewing a job candidate relative to said prioritized skills.

Neither the examiner nor the BPAI suggested that the claim would fail under Section 101. However, in its brief to the Federal Circuit, the USPTO indicated that the claim certainly failed the machine or transformation test (as well as being obvious). The USPTO explained the delayed Section 101 analysis based on internal USPTO delay -- the examiner's rejection was entered in July 2007, before the Federal Circuit's Bilski decision. The USPTO brief only mentions the patentable subject matter issue in a footnote (FN7). However, the issue will likely arise -- especially if the obviousness rejection is reversed.

Accenture Global Servs. GmbH v. Guidewire Software, 2010 U.S. Dist. LEXIS 65193 (D. Del. 2010)

In the Accenture case, district court Judge Sue Robinson has requested briefing on whether Accenture's asserted patents are invalid based on Bilski v. Kappos. The court had previously delayed its ruling on Section 101 pending outcome of that case.

Accenture's claim 1 reads as follows:

Claim 1. A method for generating a file note for an insurance claim, comprising the steps of, executed in a data processing system, of:
prefilling a first set of fields with information identifying a file note, said information comprising at least one suffix indicating a type of insurance coverage for a participant in a claim and identification of the participant, wherein the at least one suffix is preselected from one or more types of insurance coverage applicable to the claim;
obtaining a selection of fields of a first set of fields from a user, the selection identifying information for a second set of fields;
displaying in the second set of fields, the information identified by selection of field of the first set of fields;
permitting the user to add data to a predefined text area related to each field of the second set of fields based on the selected fields;
generating a file note that contains the first set of fields, the second set of fields, and the data in the predefined text area;
identifying a level of significance of the file note; and
storing the file note with the identified level of significance in a claim database including file notes associated with the claim.

Guest Post on Bilski: Throwing Back the Gauntlet

Guest Post by Shubha Ghosh, Vilas Research Professor & Professor of Law at the University of Wisconsin Law School

A year and a half ago, the Federal Circuit threw down a gauntlet in its Bilski opinion, extensively citing Supreme Court precedent to come up with the “machine or transformation test” to determine when a process constitutes patentable subject matter. Now the Supreme Court has rejected the Federal Circuit’s conclusion that “machine or transformation” is the only test to use and provided an additional basis for why Bilski’s patent for a method of hedging risk is not patentable. In doing so, the Supreme Court has thrown back the gauntlet, leaving scholars and the Patent Bar to speculate on where the USPTO and the Federal Circuit might go with using patentable subject matter as a limit on patentability. When the smoke clears, the Bilski opinion will appear a lot like the KSR decision from 2007 and that should not be surprising since Justice Kennedy authored both.

Here are the highlights of Bilski v. Kappos.Justice Kennedy‘s opinion of the court unanimously affirmed the Federal Circuit’s ruling that Bilski’s patent should be rejected. Where the nine justices agree is that the Federal Circuit erred in distilling from precedents the “machine or transformation” test as the sole one to determine when a process is patentable subject matter. The Court based this ruling on the definition of process in Section 100 of the Patent Act and its own precedents (from the 1970’s and 1981) in Gottschalk v Benson, Parker v Flook, and Diamond v Diehr. There also was agreement that patentable subject matter is broad with limits that are finite and discernible, rather than open ended.   One of these limits is no patents for abstract ideas, and there is unanimity that Bilski’s claims for methods of hedging were too abstract, describing a general process well established in the field. In short, there was unanimity in rejecting the “machine or transformation” test as the sole test for identifying a patentable process and affirming the well known exceptions from patentable subject matter: laws of nature, physical phenomenon, and abstract ideas.

In terms of method, Bilski v. Kappos reminds me of the Canadian Supreme Court’s 2002 decision in Harvard College v. Canada (Commissioner of Patents), which rejected a patent on a multicellular living organism.   Both decisions relied heavily on a strict reading of the statute with the Canadian Supreme Court ruling that the word “invention” in the Canadian patent statute did not include living organisms. The Canadian Supreme Court decision, however, seemed to be sending a clear message to the Canadian Parliament to amend the statute if necessary. By contrast, it is not clear what the U.S. Supreme Court’s message is in Bilski. The opinion was a response to the Federal Circuit’s mischaracterization of Supreme Court precedent as a “machine or transformation” test. But at a deeper level, one is left wondering what guidance the Supreme Court is providing for practitioners, scholars, and policymakers. The Court throws the gauntlet back to the Federal Circuit, and presumably they will now take the new precedent and use it to mold patent practice.

The lack of clarity is reflected in part in the Justice Breyer concurrence, joined by Justice Scalia, providing four guiding principles for how to determine whether a process is patentable subject matter. The four principles are: (i) there are limits on patentable subject matter; (ii) transformation is an important “clue” to when a process is patentable subject matter: (iii) machine or transformation is not the sole test for determining when a process is patentable subject matter; and (iv) the “useful, concrete, tangible” test does not describe the full scope of what constitutes patentable subject matter.   These four distill down to the principle that limits on patentable subject matter have something to do with transformation to a physical state, but that usefulness, concreteness, and tangibility do not describe the extent of patentable subject matter. Justice Breyer’s principles imply that there are limitations on “dubious” patents, such as those for “exercising a cat with a laser pointer” that have nothing to do with machine or transformation. The problem is we have no sense of what those additional limitations are.

Undoubtedly, more litigation is on the way, and perhaps the Court will hear another case involving either a medical diagnostic patent or a “dubious” patent. But the Bilski case will have immediate impact on how patents are prosecuted.   After the Supreme Court’s 2007 KSR decision, patent examiners latched onto the Supreme Court’s language about “common sense” to issue obviousness rejections because a claimed combination was deemed “common sensical.” We can predict similar responses post-Bilski. The Court did not kill machine or transformation; it is now just one test. Patent examiners can still use the test as a basis for rejection. In addition, the Court’s emphasis on abstract ideas creates another basis for rejecting patents for lack of patentable subject matter.

Specifically, the Court has now revived the Gottschalk-Parker-Diehr line of cases, which were established before the creation of the Federal Circuit and which the Federal Circuit had distilled over time into the expansive “useful-concrete-tangible” approach to patentable subject matter and then into the “machine or transformation test.” In effect, the Supreme Court by reviving its precedent has negated over twenty-five years of the Federal Circuit’s attempts at doctrine. This revival opens up possibilities for examiners to rethink the relationships among process, machine, and the physical world. “Dubious” patents may be rejected because the physical phenomenon is trivial or too preemptive of the field. Patent claims might require closer connection to a machine embodiment as opposed to an abstracted, disembodied form.   An interesting question to ask is whether the patent at issue in State Street would survive the analysis proposed by Bilski.   On the one hand, the asset allocation method at issue is arguably as abstract as the hedging method. On the other hand, the method seems closely tied to a machine to give the process some specific limits.  

Ultimately, Bilski v Kappos says more about how patent law is made in the United States than about patentable subject matter. By setting the clock back to 1982, the Supreme Court is telling the Federal Circuit to try again in devising workable rules for patent law. The Federal Circuit wrote an opinion that was goading the Supreme Court to address the issue of patentable subject matter after nearly three decades. The resulting opinion raises some fundamental and unsettled questions and, unfortunately, gives us the same, old answers.

Bilski v. Kappos

Although Bilski's claims were held unpatentably abstract, the Supreme Court has re-affirmed that the door to patent eligibility should remain broad and open.

Bilski v. Kappos (Supreme Court 2010)(08-964)

The Supreme Court has issued its opinion in Bilski v. Kappos. In the decision, the Supreme Court affirmed that Bilski’s risk-management method was not the type of innovation that may be patented. However, rather than using the Federal Circuit's "machine-or-transformation test", the court simply relied on prior precedent to find the claimed method unpatentably abstract. Justice Kennedy authored the majority opinion. Justices Breyer and Stevens both wrote concurring opinions.

Business as Usual: In general, the opinion offers no clarity or aid for those tasked with determining whether a particular innovation falls within Section 101. The opinion provides no new lines to be avoided. Rather, the outcome from the decision might be best stated as "business as usual."

Today, the Court once again declines to impose limitations on the Patent Act that are inconsistent with the Act’s text. The patent application here can be rejected under our precedents on the unpatentability of abstract ideas. The Court, therefore, need not define further what constitutes a patentable “process,” beyond pointing to the definition of that term provided in §100(b) and looking to the guideposts in Benson, Flook, and Diehr.

By refusing to state any particular rule or categorical exclusion, the Court has almost certainly pushed Section 101 patent eligibility to the background in most patent prosecution and litigation.

Business Methods: Section 101 does not categorically exclude business methods from patentability. Rather, the court noted that the prior-use defense found in Section 273(b)(1) of the Patent Act "explicitly contemplates the existence of at least some business method patents. . . . [B]y allowing this defense the statute itself acknowledges that there may be business method patents."

Software: Although the court expressly refused to rule on the patentability of software, it appears that software will largely remain patentable. At minimum, the decision would bar any categorical exclusion of software patents. The court neither endorsed nor rejected the Federal Circuit's past interpretations of Section 101 -- Noting that "nothing in today’s opinion should be read as endorsing interpretations of §101 that the Court of Appeals for the Federal Circuit has used in the past. See, e.g., State Street, 149 F. 3d, at 1373; AT&T Corp., 172 F. 3d, at 1357."

Abstract Idea: The one thing that all nine justices agreed upon is that Bilski's method of hedging risk was not patentable because it is an abstract idea "just like the algorithms at issue in Benson and Flook."

 

The concept of hedging, described in claim 1 and reduced to a mathematical formula in claim 4, is an unpatentable abstract idea, just like the algorithms at issue in Benson and Flook. Allowing petitioners to patent risk hedging would preempt use of this approach in all fields, and would effectively grant a monopoly over an abstract idea.

Petitioners’ remaining claims are broad examples of how hedging can be used in commodities and energy markets. Flook established that limiting an abstract idea to one field of use or adding token postsolution components did not make the concept patentable. That is exactly what the remaining claims in petitioners’ application do. These claims attempt to patent the use of the abstract idea of hedging risk in the energy market and then instruct the use of well-known random analysis techniques to help establish some of the inputs into the equation. Indeed, these claims add even less to the underlying abstract principle than the invention in Flook did, for the Flook invention was at least directed to the narrower domain of signaling dangers in operating a catalytic converter.

It is unclear to me how patent office examiners will be able to apply the test for abstract ideas in any meaningful way. I suspect that they will not. Rather, the best advice for the USPTO is to focus on Section II-A of Justice Kennedy's opinion. There, the opinion recognizes that Section 101 patent eligibility is "only a threshold test." To be patentable, the invention must also "be novel, see §102, nonobvious, see §103, and fully and particularly described, see §112."

What is the test?: 35 USC 101 offers patent protection for "any new and useful process, machine, manufacture, or composition of matter." Here, the focus was on the definition of a "process" because Bilski's patent application was written to claim a method of hedging risk. Although the majority opinion refused to define the term process, it did write that the machine-or-transformation test developed by the Federal Circuit does not define what is (and is not) a patentable process. Rather, the Court held that the machine-or-transformation offers "a useful and important clue, an investigative tool, for determining whether some claimed inventions are processes under §101. The machine-or-transformation test is not the sole test for deciding whether an invention is a patent-eligible process." As a "clue," the machine-or-transformation test likely correlates with the existence of patentable subject matter. However, some patent claims that fail the test will still be patentable and other patent claims that pass the test will still be ineligible.

Bilski v. Kappos

90% chance that Bilski will be decided this morning.

Bilski v. Kappos

There is a good chance that the Supreme Court will issue a decision in Bilski v. Kappos later this morning. Supreme Court specialist Tom Goldstein writes hopefully: “The longest-outstanding case is Bilski, the business methods patent case. It has likely taken this long because the Court is being very careful with the details, and perhaps because of separate opinions addressing issues like software patents.” 

UPDATE: No decision today. The court will release opinions on Thursday (June 24) and again next Monday.

Bilski v. Doll: Reconsidering Patentable Subject Matter

Bilski v. Doll (Supreme Court 2009)

The Supreme Court has granted certiorari in an important case challenging the scope of patentable subject matter. [Order]

Questions Presented:

Whether the Federal Circuit erred by holding that a “process” must be tied to a particular machine or apparatus, or transform a particular article into a different state or thing (“machine-or-transformation” test), to be eligible for patenting under 35 U.S.C. § 101, despite this Court’s precedent declining to limit the broad statutory grant of patent eligibility for “any” new and useful process beyond excluding patents for “laws of nature, physical phenomena, and abstract ideas.”

Whether the Federal Circuit’s “machine-or-transformation” test for patent eligibility, which effectively forecloses meaningful patent protection to many business methods, contradicts the clear Congressional intent that patents protect “method[s] of doing or conducting business.” 35 U.S.C. § 273.

Supreme Court Asked to Expand Defenses to Patent Infringement

IGT v. Aristocrat Tech of Australia (on petition for certiorari)

Every year, the PTO revives hundreds of unintentionally abandoned patent applications, and about half of those eventually issue as patents (not counting continuations and other descendants).

In the IGT case, the gaming-manufacturer was sued for allegedly infringing two of Aristrocrat's slot-machine patents. The first patent stemmed from an Australian provisional application that was followed by an international PCT filing. At the national stage in the US, the applicant missed the filing deadline but was able to convince the PTO to revive the application as unintentionally abandoned. The second patent is a continuation from the first.

In court, IGT has argued the revival was improper and thus, that the patents are invalid. IGT reasoned (and the district court agreed) that the revival was improper because the PTO lacked authority to revive national stage applications that were unintentionally filed late. Rather, the statute arguably only allows revival of applications upon proof that the tardiness was unavoidable.

Without determining the proper scope of the PTO's revival authority, the Federal Circuit rejected IGT's argument - holding that improper revival is not a "cognizable defense" to patent infringement and reminding defendants that a patent is not invalid simply because the PTO erred in issuing the patent.

Enumerated Defenses in Litigation: Section 282 of the Patent Act defines the defenses available against charges of patent infringement. These enumerated defenses include:

1. Noninfringement …,
2. Invalidity of the patent or any claim in suit on any ground specified in part II of this title as a condition for patentability,
3. Invalidity of the patent or any claim in suit for failure to comply with any requirement of sections 112 or 251 of this title.
4. Any other fact or act made a defense by this title.

In its analysis, the Federal Circuit found that improper revival did not fall within any of the four categories of defenses - and thus cannot be raised as a litigation defense. The case implicitly calls into question other traditional defenses such as nonstatutory double patenting, improper inventorship. IGT argues that the decision also implies that a defendant could not challenge a patent based on its expiration due to failure to pay maintenance fees. Of course, a defendant should have some mechanism for challenging an improperly revived patent - either through the courts or a post-grant procedure at the PTO. Under the Federal Circuit's rule, however, a typical defendant would have no recourse. (Two potential avenues could be (1) inequitable conduct in the revival and (2) trigger an interference.)

Leaving the PTO's revival grant's unchallengeable is particularly troublesome because of the serious lack of transparency in the petitions office. Pre-grant revivals are tucked away in individual prosecution file wrappers and cannot be searched in any public database. Thus, the public is left without any check on the system at either the micro or macro level.

Petition for Certiorari: IGT has petitioned the Supreme Court for a writ of certiorari and has garnered the support of the group of usual defendants (Cisco, Dell, Google, Microsoft, etc.) with the simple question:

Whether a patent infringement defendant may assert as a defense the fact that the patent resulted from an abandoned application that was not revived according to the requirements prescribed by Congress.

In several ways, this cases parallels the other recent Supreme Court patent cases such as KSR, eBay, and MedImmune. At least as history tells the story, each of those cases began with a rigid rule created by the Federal Circuit to favor patent holders. In each case, the Supreme Court softened the rule to add flexibility in a way that favors the defendants. In KSR, the rigid TSM test for applying multiple references during obviousness analysis was relaxed. In eBay, the rule strongly favoring injunctive relief was relaxed. And, in MedImmune, the rule setting a reasonable apprehension of a lawsuit as a condition precedent to a declaratory judgment action was also relaxed. In the IGT case at hand, the Supreme Court has the opportunity to tear down another rigid application of the law and open a new avenue for defendants to challenge a patent holder's rights.

Invalidity of the patent or any claim: Although slightly off-topic, I am intrigued by the wording of Section 282, which creates the defense of "invalidity of the patent or any claim." (Emphasis added). Ordinary validity issues focus on individual claims. Is the claim anticipated or obvious? Is the claim definite, fully described, and enabled, and does it properly claim patentable subject matter? The general focus on the validity of claims begs the question of what we mean by "invalidity of the patent." IGT's theory of invalidity based on improper revival is bolstered here because it would breathe meaning into the statutory invalid "patent."

Aristocrat's opposition and any amici in opposition are due April 22.

Bilski v. Doll: Round I of Amicus Briefs

Bilski v. Doll (on petition for writ of certiorari 2009)

In a 2008 en banc decision, the Federal Circuit affirmed a Patent Office ruling that Bernard Bilski’s claimed method of hedging the risk of bad weather through commodities trading was not patent eligible under Section 101 of the patent act. The Court applied a “machine-or-transformation test” as the only test to be used in determining whether a claimed process is eligible for patenting under § 101. The decision holds that a claimed process either (1) be tied to a particular machine or apparatus or (2) transform a particular article into a different state or thing. Although the Court identified the Bilski test as the only test, it added two corollaries: (1) the addition of a mere field-of-use limitation without other meaningful limits on claim scope will not render a method claim patent eligible; and (2) insignificant extra-solution limitations will not render a method claim patent eligible.

Bilski has petitioned the Supreme Court to hear its appeal and look at the question of patentable subject matter for the first time in a generation. Diamond v. Chakrabarty and Diamond v. Diehr together opened the door for broader patent eligible subject matter. Notably, Justice Stevens – author of the Diehr dissent – is the only justice still on the bench. Bilski’s petition asks two questions:

1.       Whether the Federal Circuit erred by holding that a “process” must be tied to a particular machine or apparatus, or transform a particular article into a different state or thing … despite this Court’s precedent declining to limit the broad statutory grant of patent eligibility for “any” new and useful process beyond excluding patents for “laws of nature, physical phenomena, and abstract ideas.”

2.       Whether the Federal Circuit’s “machine-or-transformation” test for patent eligibility, which effectively forecloses meaningful patent protection to many business methods, contradicts the clear Congressional intent that patents protect “method[s] of doing or conducting business.” 35 U.S.C. § 273.

The first round of Amicus briefs – those supporting the petition – have now been filed. The PTO’s briefs and briefs in opposition to the petition are due in early April.

Applying Supreme Court Precedent

Carlsbad Technology v. HIF Bio (Supreme Court 2009)

The Supreme Court held oral arguments in this case on February 24. In its opinion, the Federal Circuit held that it lacked appellate jurisdiction to review a district court order to remand a case back to state court. The Federal Circuit's decision goes against precedent set by the Third, Fourth, Fifth, Sixth, Seventh, Eighth, Ninth, Tenth and Eleventh Circuits. And, the case appears in conflict with the Supreme court's Powerex v. Reliant (2007) decision.

During oral arguments the Justice Roberts was considering when lower courts follow Supreme Court holdings when he made the following statement:

CHIEF JUSTICE ROBERTS: Well, they don't have a choice, right? They can't say, I don't like the Supreme Court rule so I'm not going to apply it, other than the Federal Circuit.

(Laughter).

  Judge Linn recently gave a Keynote address to the PTO examiner's corps. [Read it here]. Judge Linn started as a patent examiner in 1965. The following are some quotes from the full speech:
  
  
  • "Your job is much harder now than it was for me all those years ago. The technology of today's inventions is immensely more complex than ever before. The length and breadth of applications is greater. The volume of prior art is much larger. The legal issues are more intricate and harder to comprehend. And the law is in a continual state of change. Compounding all of this is the perception among some individuals that the work of the PTO in general, and the examiners in particular, is somehow of secondary importance and questionable quality. It is commonly said that the real action in patents is in private or corporate practice."
  • "Your job is to grant patents—valid patents. And that takes a combination of skills, reasoning and informed judgment. The Examiner's task is to assess the patentable merits of each invention, as presented, and to grant patents where patents are due. No applicant wants an invalid patent. Similarly, no examiner wants to grant an invalid patent. Thus, both the applicant and the examiner play parallel and complementary—not contradictory— roles in seeing to it that valid patents are issued."
  • "[R]eading legal decisions, particularly those of the Board and the Federal Circuit, is not only the best way to learn how to make the tough decisions you are regularly called upon to make, but also the best way to make your job easier and more enjoyable. You might ask, "why should I bother to read decisions of the Board and the Federal Circuit? After all, I have all the guidance I need in the MPEP, and I don't have time to spend reading other cases that have nothing to do with me." The answer is that the cases bring to life the statutes and rules you are required to apply and give you real world examples of how those statutes and rules apply in similar cases. The MPEP has some guidelines, but they are just a sampling and cannot possibly reflect the full range of claims and circumstances you face every day. Keeping up with the law by reading decisions of the Board and the Federal Circuit will allow you to master your craft and will result in your standing out from your peers."
  • "The last point I want to make is to not forget about §112. … [I]t is not correct to trivialize or ignore these kinds of Informalities [such as claims that are vague and indefinite or lacking in support in the written description]. Indeed, these kinds of problems affect not only the applicant but the public as well in a significant way. … In case after case before my court, the central debate revolves around the meaning of claims terms that, for example, were added during prosecution and do not appear anywhere in the written description. For those cases, the meaning of the claim limitation has to be inferred from other words, leaving the issue open to unnecessary dispute and leading frequently to protracted and costly litigation. You have the authority and the responsibility to not let that happen and to insist that applicants use words in the claims that find unambiguous and full support in the written description."
  
  
  
  

Federal Circuit Takings Case: Set Up for Supreme Court Review

Casitas Municipal Water v. US (Fed. Cir. 2009) (en banc denial) (MAYER, SCHALL , and MOORE*)

Casitas is not a patent case, it is a takings case involving regulatory restrictions on water use imposed by US Government. The Federal Circuit has jurisdiction over this takings claim against the US Government because it is on appeal from the Court of Federal Claims (CFC). Although the Federal Circuit has denied the Federal Government's motion for en banc rehearing, a set of diverging opinions sets this case in position for likely Supreme Court review.

History: The Ventura River Project provides water supply to Ventura County, California. In 1956, the US Government granted the local government the "perpetual right to use all water that becomes available through the construction and operation of the Project." Then, in 1997, steelhead trout living in the Project became an endangered species under the Endangered Species Act (ESA), and the US Government required that Casitas construct a fish ladder and divert water over the fish ladder. Casitas complied, but filed suit in the CFC alleging that the Federal Government had taken its property without just compensation (and also under breach of contract). The CFC classified the Government action as "regulatory" rather than a "physical." In takings law, compensation for regulatory takings is much more difficult to obtain, and Casitas admitted that it could not prove the required elements. This conclusion followed the Federal Government argument that "it did not seize, appropriate, divert, or impound any water, but merely required water to be left in the stream."

Appeal: On appeal, the Federal Circuit reversed. Writing for the majority, Judge Moore concluded "that the government physically appropriated water that Casitas held a usufructuary right in."

Here, the government admits for the purposes of summary judgment that it required Casitas to build the fish ladder facility, which is a man-made concrete structure that was not a portion of the existing … The government also admits that the operation of the fish ladder required water, which prior to the fish ladder's construction flowed into the Casitas Reservoir … Specifically, the government admits that the operation of the fish ladder includes closing the overshot gate …and that the closure of this gate causes water that would have gone into the Casitas Reservoir via the Robles-Casitas Canal to be diverted into the fish ladder. … These admissions make clear that the government did not merely require some water to remain in stream, but instead actively caused the physical diversion of water away from the Robles-Casitas Canal … and towards the fish ladder, thus reducing Casitas' water supply.

In dissent, Judge Mayer rejected the physical takings argument. At base, he argued, Casitas does not actually own the water. Rather, under California law, all water sources within California "belong to the public." Even if Casitas did own the water flow, Mayer would have seen the endangered species requirements as regulatory because the requirements simply force a specific use of the water rather than take it away.

En Banc Rehearing: In what looks like a 7-5 (or 6-6) vote, the Federal Circuit denied a rehearing en banc. Judge Moore wrote a new opinion defending her original approach in the original opinion. In particular, Judge Moore focused on the "facts as presented" in the case. "[T]he government conceded (1) that Casitas had a property right in the water diverted from the Ventura River, and (2) that the government required Casitas to build and operate the fish ladder in such a way as to permanently appropriate water in which Casitas had the conceded property right." Based on those two facts, the holding of a physical takings was easy.

Judge Gajarsa would have heard the case en banc. Gajarsa (joined by Chief Judge Michel and Judge Dyk) saw the taking as clearly regulatory in form because nothing had actually been taken by the US Government.

This denial implicates fundamental questions regarding takings law. The panel majority's opinion suggests that a government action can be construed to be a physical taking even if no physical proprietary interest has actually been taken by the United States. This is contrary to present Supreme Court law and contrary to our case law. Accepting this analysis of the panel majority eliminates the fine distinction and balance that has been established by the Supreme Court between physical and regulatory takings. Moreover, it eliminates the ability of the legislature to provide for limited and parsimonious legislation protecting endangered species.

Notes:

• Republican vs. Democrat: Moore's position is clearly one of stronger property rights while Gajarsa/Mayer's position is in favor of regulatory power of the government. It appears that this decision falls along political lines. Those thinking of the regulation as a physical taking (Moore, Schall, Rader, JJ) are all Republican appointees. Three of the five thinking of the regulation as regulatory in nature are Democratic appointees (Linn, Dyk, Gajarsa, JJ are all Clinton appointees; Michel, CJ, and Mayer, J, are Reagan appointees). At least three of the four other judges voted to deny a rehearing. Of those four, three are Republican appointees (Newman, Lourie, Prost, JJ, are all Republican appointees; Bryson, J, is a Clinton appointee). As you can see here, eight of the twelve active Federal Circuit judges are Republican appointees.

Aventis Files for Certiorari: Challenging Federal Circuit's Low Standard for Intent to Deceive in Inequitable Conduct Proceedings

Aventis Pharma v. Amphastar Pharmaceuticals and Teva (on petition for a writ of certiorari)

In a split 2008 decision, the Federal Circuit affirmed a lower court decision holding two Aventis patents unenforceable due to inequitable conduct. The patents cover a low molecular weight form of the blood thinner heparin and is marketed under the Lovenox brand. The alleged offense involved an Aventis failure to report that its tests showing improved drug half-life used a different dosage than the tests on prior-art compound. Inequitable conduct requires proof of both materiality and intent to deceive. Here, the intent was shown only through circumstantial evidence.

In a strongly worded dissent, Judge Rader argued that inequitable conduct law should be restricted to "only the most extreme cases of fraud and deception." Rader also discusses how past inequitable conduct should be correctable.

Now, Aventis has hired Supreme Court powerhouse (and champion of the Federalist Society) Ted Olson and has asked the Supreme Court for its view. Aventis posits as an extension of Judge Rader's dissent - arguing that inequitable conduct should not be a viable cause of action when the mens rea evidence only rises to gross negligence. The question presented:

Under the judge-made doctrine of “inequitable conduct,” a federal court may decline to enforce an otherwise valid patent that was procured through fraud or deceit. Precision Instrument Mfg. Co. v. Auto. Maint. Mach. Co., 324 U.S. 806 (1945). As befits the punitive nature of the doctrine, this Court has invoked it only in extreme circumstances involving “deliberate,” “corrupt,” “sordid” and “highly reprehensible” misconduct. Some panels of the Federal Circuit have similarly limited the inequitable conduct doctrine to deliberately planned and carefully executed schemes to defraud, but other Federal Circuit panels—including the majority in this case— have adopted a “sliding scale” under which “less intent” is required as the materiality of an omission or misrepresentation increases. The question presented is:

Whether a court may refuse to enforce an otherwise valid patent on the basis of an inequitable conduct determination premised on a sliding scale between intent and materiality, effectively permitting a finding of fraudulent intent to be predicated on gross negligence.

Aventis has written a strong petition, amici briefs in support of the Aventis position would be due by February 25.

Bilski Petitions the Supreme Court to Decide Issues of Patentable Subject Matter

Bilski v. Doll (on petition for certiorari)

In Bilski, the Court of Appeals for the Federal Circuit applied the “machine-or-transformation test” as the only test to be used in determining whether a claimed process is eligible for patenting under § 101. The decision holds that a claimed process either (1) be tied to a particular machine or apparatus or (2) transform a particular article into a different state or thing.

Bilski’s claimed method of hedging the risk of bad weather through commodities trading had been rejected by the USPTO as lacking patentable subject matter. On appeal, the Federal Circuit affirmed – finding that the method failed the machine-or-transformation test.

Now, Bilski has petitioned the Supreme Court for a writ of certiorari — asking the high court to determine whether the new test of patentable subject matter is the correct test.

The petition asks two questions:

Whether the Federal Circuit erred by holding that a “process” must be tied to a particular machine or apparatus, or transform a particular article into a different state or thing … despite this Court’s precedent declining to limit the broad statutory grant of patent eligibility for “any” new and useful process beyond excluding patents for “laws of nature, physical phenomena, and abstract ideas.”

Whether the Federal Circuit’s “machine-or-transformation” test for patent eligibility, which effectively forecloses meaningful patent protection to many business methods, contradicts the clear Congressional intent that patents protect “method[s] of doing or conducting business.” 35 U.S.C. § 273.

Under Supreme Court rules, any amici brief in support of the petitioner (Bilski) would be due within thirty days (Feb 27). Those in support of the respondent (PTO) would be due the dame day, but the PTO will likely seek an extension.

Supreme Court Patent Update

Completed Cases: The Supreme Court has denied certiorari of two pending appeals: BPMC v. California and Rattler Tools v. Bilco. In BPMC, the patentee had challenged the Western state’s defense of sovereign immunity. In Rattler Tools, the appeal challenged a non-precedential claim construction opinion.

Upcoming Case: In a recently filed petition, 800 Adept has asked the Supreme Court to build on its 1995 Markman decision and consider “whether a district judge’s construction of a patent claim is ever entitled to deference upon appellate review, or, instead, are all such claim constructions reviewable only de novo, as the Federal Circuit has, over many dissenting opinions, held?” In this case, the Federal Circuit had reversed the lower court’s claim construction and – as a consequence – also reversed the jury verdict of infringement. [Link]. FTC v. Rambus is the most likely candidate of patent cases in the petition stage. That case involves the activities of a patentee during a standard setting process. In a related case, well respected Federal Judge Sue Robinson held that Rambus could not enforce twelve of its patents against Micron as a penalty for litigation misconduct. [Link]

Patently-O Bits and Bytes No. 46: Supreme Court Edition

• In re Nuijten: The applicant has filed a petition for certiorari to overturn the Federal Circuit’s decision that a man made signal is not patentable.  Professor Duffy filed a ‘law professor’ amicus supporting the position which I signed. We argue that the CAFCs Nuijten decision improperly creates a new subject matter exclusion of transitory inventions that cannot be perceived without special equipment.  The AIPLA also filed a brief asking the Supreme Court to hear the case. [Law Professor Brief][AiplaNuijten (119 KB)]. Judge Linn’s dissent in the Nuijten decision may well serve as an additional amicus.

The Supreme Court is awaiting views from the US Solicitor General on whether the US recommends grant of certiorari.   
• Translogic v. Dudas: In this case, Translogic asks the Supreme Court to invalidate a BPAI opinion based on the unconstitutional appointment of BPAI judges. In a recent study, I showed that 83% of recent BPAI decisions included at least one judge appointed by the PTO Director rather than the constitutional required “head of department.”  Translogic has several procedural hurdles.
• Calmar v. Arminak: The design patent holder asked the Supreme Court to reverse the Federal Circuit’s application of the “ordinary observer” test that improperly excludes the most natural ordinary observer – a retail customer. On June 9, the Supreme Court Denied certiorari.

BPAI Administrative Patent Judges

There continues to be interest in the BPAI appointments problem identified by Professor John Duffy. The solution going forward is quite simple — change the law so that BPAI administrative patent judges will be appointed by the Secretary of Commerce then re-appoint the current judges.  No one is arguing that the BPAI judges are incompetent or lack qualifications for their position — only that they have been appointed in a way that runs contrary to the Constitution.  This issue may not come to a head until demanded by a court of law. The Translogic petition for certiorari is one avenue, although many more will follow until a clear resolution is reached. 

In 2000, the BPAI judge appointment law changed to require the PTO director to appoint the administrative patent judges rather than the Secretary of Commerce. Through a FOIA request, Wendy Gombert and Joel Ard from the Black Lowe firm recently obtained a listing of the 47 BPAI judges who have been appointed since the law was amended. [THE LIST].

To get some sense of the impact of these judges, I looked at the 2500+ BPAI decisions between March 2007 and March 2008 and found most of those decisions (83%) included at least one panel member that had been illegally appointed under the Duffy construction. A significant number of panels (44%) included a majority of illegally appointed judges, and about half of the opinions were authored by illegally appointed judges. By technology center, applications classified in TC1700 (Chemical and Material Engineering) had the fewest opinions drafted by the illegal appointees while TC1600 (Biochemistry and Organic Chemistry) had the most. This difference is likely primarily due to the core group of veteran TC1700 judges.

Supreme Court Decides Quanta v. LG Electronics, __ U.S. __ (2008),

Quanta v. LG Electronics, __ U.S. __ (2008)

Justice Thomas delivered the Supreme Court’s 19–page unanimous decision that provides some new life to the doctrine of patent exhaustion.  The opinion reverses the Federal Circuit and holds that under the exhaustion doctrine applies to the authorized sale of components that “substantially embody” a process patent. Here, Intel’s authorized sale of chip components to Quanta exhausted LGE’s patent rights. 

Buried in this statement are two important holdings: (1) method claims can be subject to exhaustion and (2) sales of products that that do not fully practice the invention can still trigger exhaustion when the products include essential features of the patent and the “reasonable and intended use” of the product is to practice to patent. 

In coming to its conclusions, the court reiterated its longstanding rule that “the right to vend is exhausted by a single, unconditional sale, the article sold being thereby carried outside the monopoly of the patent law and rendered free of every restriction which the vendor may attempt to put upon it.” Motion Picture Patents, 243 U. S. 502 (1917).  The Motion Picture decision is more nuanced than the even older statement from Adams, which the opinion also quotes approvingly: “[W]hen a patented item is ‘once lawfully made and sold, there is no restriction on [its] use to be implied for the benefit of the patentee.’” Quoting Adams v. Burke (1873).

Contractual Limits: Although the defendant won in this case, the Supreme Court gave some glimmer of hope to those hoping to limit the scope of patent exhaustion through specific licensing terms. In this case, the court found that the LGE-Intel license did not limit the scope of what Intel could sell.  Rather, the contract “broadly permits Intel to ‘make, use, [or] sell’” the invention. Under that interpretation of the contract, LGE’s patent rights over a particular component are extinguished as soon as that component is sold – regardless of whether the license included post-sale restrictions.  

“LGE points out that the License Agreement specifically disclaimed any license to third parties to practice the patents by combining licensed products with other components. But the question whether third parties received implied licenses is irrelevant because Quanta asserts its right to practice the patents based not on implied license but on exhaustion. And exhaustion turns only on Intel’s own license to sell products practicing the LGE Patents.”

The practical impact is that the patentee has direct power through only the first level of the production/marketing process and forces the patentee to rely on contract rather than patent rules. This shift is less preferred by patentees because (1) contract law requires agreement and privity and (2) patent law typically results in stronger relief than contracts (despite eBay).  Because there is usually a lack of privity with downstream users, and the manufacturer is unlikely to agree to be liable for improper downstream uses, it appears that a patentee will now have even more difficulty controling downstream users and purchasers.

Authorized: Despite the broad language of Adam v. Burke, the Supreme Court appears to have conceded that a license may include some restrictions.  Interestingly, the court indicated, the sale might not have been authorized if sale had been done in a way that breached the contract between Intel and LGE.

“No conditions limited Intel’s authority to sell products substantially embodying the patents. Because Intel was authorized to sell its products to Quanta, the doctrine of patent exhaustion prevents LGE from further asserting its patent rights with respect to the patents substantially embodied by those products”

In Footnote 7, the court limited its holding to patent exhaustion — and expressing “no opinion on whether contract damages might be available even though exhaustion operates to eliminate patent damages.”  This means that violation of use restrictions associated with an authorized sale will not constitute patent infringement. However, it may still constitute a breach of contract. The case says little to nothing about the growing tendency of providing products as a service rather than through the sale of goods.  Those offering the service believe that their business structure moves the deal outside of the “first sale” doctrine because the products are transferred via a license & service agreement rather than the sale of goods.

Notes:

• “The sale of a device that practices patent A does not, by virtue of practicing patent A, exhaust patent B. But if the device practices patent A while substantially embodying patent B, its relationship to patent A does not prevent exhaustion of patent B.”

California Should Not be Immune from Charges of Patent Infringement (But it is Immune)

BPMC v. California Department of Health (on petition for certiorari). [Read the Petition]

States generally support strong patent rights. Why? Because States are free to enforce their patent rights yet are generally immune from suit for infringing patents owned by others. 

The Eleventh Amendment – ratified in 1795 – provides immunity to State governments from suits by “Citizens of another State … [or] any Foreign State.” The US Supreme Court has expanded the literal reading of the amendment — holding that state immunity broadly extends to almost all lawsuits brought against a state.

A State may, of course, waive its immunity.  A classic example of waiver occurs when a state files a patent infringement lawsuit.  After filing the lawsuit, the State cannot claim immunity against related counterclaims filed by a defendant. 

The facts of this case are quite simple: Healthcare Giant Kaiser filed a declaratory judgment action against the patent holder BPMC back in 1997. The State of California intervened in that case in support of Kaiser’s position.  The DJ action was eventually dismissed for improper venue. Almost a decade later, BPMC filed an identical (mirror image) infringement action against the State asserting the identical patent and issues and in the same venue as the 1997 action.

The issue then is whether California’s original waiver of immunity also applies to this second – seemingly identical case.

On appeal, the CAFC narrowly construed California’s waiver of immunity to be limited to only the same action. The court noted precedent that the waiver would apply if BPMC had been able to file its case as a revival of the original action an “numbered as that cause of action.”

The appellate panel also rejected BPMC’s argument that the DOH should be judicially estopped from changing its position in this litigation. According to the court, the about-face was excusable because of an intervening change in the law of immunity.  In particular, during the interim, the Supreme Court decided Florida Prepaid. That case held that Congress could not legislatively eliminate a State’s sovereign immunity from patent infringement claims without showing cause under the 14^th amendment.

In its petition for certiorari, BPMC focuses on the issue of waiver due to litigation conduct. The patentee argues that its case is particularly special — because of past waiver in the same transaction. In addition, however, the patentee argues that some states – such as California – have become such major market participants in patent litigation that it would be unjust to allow immunity to continue:

California’s effort to invoke sovereign immunity selectively in this case is part of a larger scheme to use the federal courts as both a sword and a shield. California embraces federal patent jurisdiction when it seeks to benefit but avoids that jurisdiction when it faces liability. Through its frequent voluntary invocation of federal patent jurisdiction, however, California has unambiguously demonstrated that it is generally amenable to federal jurisdiction in these matters and has thereby waived its Eleventh Amendment immunity.

Although not likely, BPMC has a better than average chance at certiorari.  It is a fundamental constitutional question with a circuit split and changed business circumstances (States are now major patent players).  Another plus is that noted Supreme Court specialist Andy Pincus is on the brief and would likely argue for BPMC.

Supreme Court to Decide Patent Exhaustion Case

Quanta v. LG Electronics (Supreme Court 2007)

The Korean chaebol LG licensed a set of patents to Intel.  The license expressly excludes Intel's customers and similarly does not cover any customer product made by combining an Intel product with a non-Intel product.

When LG sued a host of Intel chip-based computer manufacturers for infringement, they complained of attempted double-dipping.  According to the defendants (including Quanta), their use of licensed Intel chips implicated the first sale doctrine of patent exhaustion.

Now the Supreme Court has granted certiorari to determine whether LG’s narrow license terms avoid exhaustion.

Question presented: “Whether the Federal Circuit erred by holding, in conflict with decisions of this Court and other courts of appeals, that respondent’s patent rights were not exhausted by its license agreement with Intel Corporation, and Intel’s subsequent sale of products under the license to petitioners.”

Exhaustion – also known as the first sale doctrine – serves as a default rule in both patent and copyright laws. Under the principle, a license fee is only be charged one time per object. Thus, a rights holder controls the first sale of a protected object, but does not control subsequent sales. The copyright rule is codified in Section 109. The patent rule, however, is only based on case law.

Lower Court Ruling: The lower court found that Intel’s "unrestricted" license and Intel's sale of its chips under the license exhausted LG's rights to any additional patent recovery.

CAFC Ruling: On appeal, the Court of Appeals for the Federal Circuit (CAFC) reversed, finding that when restrictions are placed on a license, "it is more reasonable to infer that the parties negotiated a price that reflects only the value of the ‘use’ rights conferred by the patentee." The appellate panel found that there was no exhaustion because of express conditions on the use of Intel's licensed products -- specifically that the products could not be combined with non-Intel parts.

Quanta's argument is quite simple:

• Intel sold chipsets to the petitioners;
• Those sales were fully authorized under the LG license and were made without restriction;
• Therefore, LG's patent rights are exhausted.

Quanta goes on to say that under Supreme Court jurisprudence, a sale cannot be conditional. (No improper restraints on alienation).  And, without citing Arizona Cartridge, the petition lists a set of upcoming problems if conditions for sale are allowed for patented items:

[T]he Federal Circuit's new jurisprudence threatens to kick off a new era of "notices" attached to sold goods.  Obvious candidates include "single use only," "no use outside of Massachusetts," "no repair," "no resale," or "no resale for less than the price of purchase."

On the other side, LG points-out that Intel made a business decision not to cover its customers.  Because of that decision, Intel received a cheaper license, but now the customers must make-up the difference.

[When there are no patent misuse or notice concerns,] parceling out of the exclusivity rights is simply a matter for negotiation in the marketplace, not for a legal override of commercially fashioned terms.

An amicus on behalf of Dell, HP and others identifies the origin of the current CAFC precedent: Mallinckrodt.

Mallinckrodt held that a restriction on the post-sale use and enjoyment of a patented article is enforceable under the patent laws as long as it does not “venture[] beyond the patent grant and into behavior having an anticompetitive effect not justifiable under the rule of reason.”

According to the Amicus (and Quanta), the Mallinckrodt decision and its progeny do not follow Supreme Court precedent as stated in Univis Lens.

Univis Lens ... held that the authorized sale of an article manufactured “under the patent” exhausts all patent claims in the article regardless of any purported limitation on the subsequent use and enjoyment of the article. . . Univis Lens held that a condition on the post-sale use and enjoyment of a patented device violated the antitrust laws because it was not enforce-able under the patent laws, and thus was not protected against antitrust scrutiny. See 316 U.S. at 252 (“[t]he price fixing features of appellees’ licensing system, which are not within the protection of the patent law, violate the Sherman Act”).United States v. Univis Lens Co., 316 U.S. 241 (1942)

KSR and the Line Between Fact and Law

By Professor Chris Cotropia

Well, we have gotten early indications from the major patent players as to how the substantive part of KSR will play out.  TSM still has a place in the post-KSR world, at least according to Chief Judge Michel of the Federal Circuit and Deputy Commissioner Focarino of the USPTO.  These are preliminary statements.  We will not know what the Federal Circuit or USPTO really think until the first precedential opinion or interim guidelines issue.  But these early comments make one wonder if KSR changes anything, particularly those like myself who witnessed the Federal Circuit's acceptance of, and reliance on, implicit TSM well before In re Kahn, DyStar, and Alza.

While the substantive impact may turn out to be minimal, KSR could have a significant procedural effect.  The Court appears to have shifted the line between factual and legal parts of the nonobviousness analysis, moving what was (is?) the TSM test from being a question of fact to a question of law. 

The Supreme Court in Graham established that nonobviousness was ultimately a question of law, but there were recognized underlying factual issues—content of the prior art, scope of the claims, and the level of the PHOSITA.  When the CCPA, and then the Federal Circuit, started employing the TSM test, the test became another underlying factual component of the inquiry.  As a result, there was not much left at the question of law level, and the Federal Circuit affirmed most appeals from rejections by the USPTO and or trials before district courts on the nonobviousness issue.

The Legacy of KSR v. Teleflex

Part of the legacy of KSR will depend upon how the case is treated by the Federal Circuit (CAFC). Graham v. John Deere is the seminal patent case on obviousness, and is cited by most patent decisions involving the question of obviousness.  Cases like Sakraida and Anderson's Black-Rock are much less likely to be relied-on. Sakraida, for instance, is fifty-times (50x) less likely to be cited by the CAFC than Graham -- even though Sakraida represented (until 2007) the Supreme Court's most recent pronouncement on obviousness.  Sakraida's low-level influence has waned in recent times.  For instance, the cow-dung case has only been cited once by the CAFC in the past decade. (in DyStar).

The table above shows the number of Shepard's citations found for the Supreme Court's set of obviousness decisions. Total citations include all known citations while "total court" citations include only instances where the case was cited in a court opinion. The No. 2 case (in CAFC citations) is US v. Adams. That case is notorious as the only nonobviousness case -- i.e., were the Supreme Court found the claims nonobvious.

The KSR Opinion has much more meat than Sakraida, but the case will never challenge the canonical status of Graham v. John Deere.  Of course, the question of KSR's legacy is now in the hands of the CAFC.

KSR v. Teleflex: Supreme Court on Obviousness

KSR Int'l v. Teleflex, Inc., 550 U.S. ___ (2007).

In a unanimous decision, the Supreme Court rejected any notion that the concept of obviousness in patent law can be rigidly or narrowly defined -- holding that "the obviousness analysis cannot be confined by a formalistic conception."  However, the opinion does not radically change the notion of obviousness or immediately invalidate a wide swath of already issued patents.

The question of nonobviousness comes-up in Section 103 of the Patent Act. That section declares that a patent shall not issue if "the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains."

But what is "obvious"?  Certainly, this amorphous term has continuously stumped engineers and scientists for the past 50+ years.  One particular issue involves combination inventions that take various existing elements and combine them in a new way.  When is such a combination obvious?  In an attempt to provide improved notice and regularity, the Court of Appeals for the Federal Circuit (CAFC) introduced a test that holds a combination invention is nonobvious absent some teaching, suggestion, or motivation (TSM) to combine the various parts together.

In KSR, the Supreme Court began by rejecting the CAFC's test for obviousness:

"We begin by rejecting the rigid approach of the Court of Appeals. Throughout this Court's engagement with the question of obviousness, our cases have set forth an expansive and flexible approach inconsistent with the way the Court of Appeals applied its TSM test here."

At this point, I would have expected the Court to obliterate the past twenty-five years of obviousness jurisprudence and begin again with a clean slate. It did not do that — rather, the opinion appears to simply refine the particulars of how prior-art can be combined and when a "combined patent" will be seen as obvious.  Without explicitly saying so, the Court's opinion appears to affirm the CAFC's more recent pronouncements of a flexible test of obviousness. Dystar, Alza.

Patent Value: In the short-term, this case reduces the average value of patent holdings. Courts should find it easier to invalidate patents based on expert testimony and the jury's concept of obviousness. The story also becomes more important -- and attorneys who can tell an "invention story" will be in demand.  During prosecution, inventors and experts should get their pens ready to sign declarations of patentability.

Preliminary Gems:

• PHOSITA is Creative: A person of ordinary skill is also a person of ordinary creativity, not an automaton.
• Obvious to Try: When there is a design need or market pressure to solve a problem and there are a finite number of identified, predictable solutions, a person of ordinary skill has good reason to pursue the known options within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense.
• Hindsight Bias: Rigid preventative rules that deny factfinders recourse to common sense, however, are neither necessary under our case law nor consistent with it.
• No Presumption of Validity: We need not reach the question whether the failure to disclose Asano during the prosecution of Engelgau voids the presumption of validity given to issued patents, for claim 4 is obvious despite the presumption.
• Patents Halt Innovation: Granting patent protection to advances that would occur in the ordinary course without real innovation retards progress and may, in the case of patents combining previously known elements, deprive prior inventions of their value or utility.
• Common Sense: Mentioned glowingly five separate times. 

Supreme Court Retracts Patent Protection

KSR v. Teleflex, 550 U. S. ____ (2007): In a unanimous opinion authored by Justice Kennedy, the Supreme Court held that the Federal Circuit's "narrow" & "rigid" TSM test is not the proper application of the nonobviousness doctrine of Section 103(a) of the Patent Act.

"To facilitate review, [the obviousness] analysis should be made explicit. But it need not seek out precise teachings directed to the challenged claim's specific subject matter, for a court can consider the inferences and creative steps a person of ordinary skill in the art would employ."

"A patent composed of several elements is not proved obvious merely by demonstrating that each element was, independently, known in the prior art."

"There is no necessary inconsistency between the [TSM] test and the Graham analysis. But a court errs where, as here, it transforms general principle into a rigid rule limiting the obviousness inquiry."

Microsoft v. AT&T: With a 7-1 majority, the Supreme Court has ruled in favor of Microsoft in its extended fight againt extraterritorial application of US Patent Law -- holding that Section 271(f) of the Patent Act does not extend to cover foreign duplication of software. Justice Stevens dissented.

Microsoft v. AT&T: Transnational patent Law

Microsoft v. AT&T (Supreme Court 2007).

Section 271(f) of the Patent Act expands the territorial scope of US patent protection by creating liability for exporting one or more “components” of a patented invention so that the whole invention may be practiced abroad. The statute is divided into parts one and two dealing with inducement and contributory activity respectively.

The case at hand involves Microsoft’s infringement of AT&T’s speech coding technology patent. Microsoft has conceded that its software (once installed on a computer) infringes the patent in the US. However, Microsoft has fought against paying patent royalties for sale of the same software abroad.  Microsoft’s argument, spelled out in its brief, is two-fold: (1) Software cannot be a ‘component’ as required by the statute because software code is intangible; and (2) Software copies made abroad cannot be considered ‘supplied’ from the US as required by the statute because no physical particle that Microsoft exported actually became part of the finished product.  I have previously labeled these arguments as the tangibility requirement and the molecular conservation requirement. [Link]

Now, AT&T and its supporters has filed their briefs that explain why 271(f) should encompass foreign copies of software shipped from the US. [Petitioner and Gov’t briefs are discussed here]

AT&T’s Brief on the Merits:

Tangibility: AT&T attacks the tangibility requirement head-on, arguing that there is no such requirement.

[The software] is plainly a component of [the patented] device, just as a unique collection of intangible words is a component of any book bearing the title Moby-Dick, even though those words, too, must be combined with ink and paper before the book can be read.

Of course AT&T is correct — the statute does not spell-out any tangibility requirement, and Microsoft’s statutory argument is, at best implicit. AT&T’s arguments are supported by business practice as well. Software and hardware are developed and sold separately, and each side can easily be though of as providing components of the whole.

Molecular Conservation Requirement: AT&T takes a different view of the statutory requirement that the components be “supplied” from the US. In AT&T’s story, “supplied” means satisfying a need or furnishing.  Using a but-for analysis, AT&T makes clear that without Microsoft’s shipment of the code abroad, it would not have ended-up in the foreign computers.

Here, the Windows object code is present in the foreign made computers only because Microsoft “provided” or “furnished”—in a word, supplied—it from the United States, via golden master disk or electronic transmission.

As it stands, the AT&T brief is well written and convincing on its own — the major problem being that it leads with a petty argument for dismissal.

Philips Corporation also filed a brief in support of AT&T.  Philips makes several arguments, two of which I discuss here:

1. In today’s market, software and hardware companies do compete head-to-head.  A finding that software export is noninfringing would be at the expense of electronics companies because hardware exports would continue to be considered infringing.  Thus, awarding the win to Microsoft here may free the software industry, but will even further damage the hardware export industry.
2. In many ways, this case is about the size of damages. Microsoft hopes that copies made abroad will not be seen as infringing because those copies were not literally shipped from the US.  Philips points out under the rules of consequential damage calculations, Microsoft would owe damages for sales of all copies even if 271(f) only covered the initial master disk shipment.

WARF, California, and RCTech filed a joint brief in support of AT&T. These holders of strong bio-related patents see the potential that this case could narrow the scope of their protection. WARF points-out how Microsoft comes to the table with unclean hands:

When it suits its interests, even Microsoft acknowledges that the number of units it supplies is not limited by the number of golden masters it sends abroad. In Microsoft Corp. v. Comm’r of Internal Revenue, Microsoft argued that it was entitled to tax deductions . . . for all foreign sales of software replicated from Microsoft’s golden master abroad, claiming that such copies were "export property" under the statute. The Ninth Circuit . . . agreed with Microsoft that all copies created from the golden master were export property, thereby providing Microsoft with another $31 million in claimed deductions for 1990 and 1991.

BAYHDOLE25.inc is an educational NGO that supports, as you might guess, the Bayh Dole act (at its 25th anniversary).  In a brief supporting AT&T, BD25 argues for the protection of intangible assets — especially assets that are replicable and intended to be replicated.  These include software code, cell lines, patented seeds, DNA, etc. Replicable assets are important and should be protectable.

Text of 35 USC 271(f)

(1) Whoever without authority supplies or causes to be supplied in or from the United States all or a substantial portion of the components of a patented invention, where such components are uncombined in whole or in part, in such manner as to actively induce the combination of such components outside of the United States in a manner that would infringe the patent if such combination occurred within the United States, shall be liable as an infringer.

(2) Whoever without authority supplies or causes to be supplied in or from the United States any component of a patented invention that is especially made or especially adapted for use in the invention and not a staple article or commodity of commerce suitable for substantial noninfringing use, where such component is uncombined in whole or in part, knowing that such component is so made or adapted and intending that such component will be combined outside of the United States in a manner that would infringe the patent if such combination occurred within the United States, shall be liable as an infringer.

Merges: Back to the Shadows, or Onward and Upward? Current Trends in Patent Law

By Professor Robert Merges

When no less an authority than Hal Wegner of Foley and Lardner starts worrying about the current direction of the Supreme Court on patent issues, it’s time to sit up and take notice. I have heard some of these concerns in the past few years, especially in the wake of the eBay injunction case. But when Hal sent around his widely-read “top 10 cases” email recently, I could see that his outlook had taken a serious turn for the worse. Here are some quotes from the recent Wegnerian missive:

“eBay philosophically piggybacks off an anti-exclusionary right climate in the electronics/software/manufacturing industries that has had a constant, anti-patent drumbeat in the academic and business communities and in the mainstream press. The Court has listened. . . .

[A] decidedly anti-patent core nucleus from the Douglas era is reforming at the Court that - save for Justice Stevens - had disappeared in the wake of the 1980 Chakrabarty and 1981 Diehr decisions . . . .

I believe this is a fairly mainstream view, at least among some chem/biotech/pharma practitioners. And despite how much Hal knows about all things patent (things he has generously shared with me and other academics over the years), I have to disagree with his assessment. Even more, though, I am worried about the larger implications of these views. The wedge between the pharma/biotech/manufacturing and the software/electronics views of the patent world is on one level just a normal development in a vibrant and growing field. But beyond a certain point, it is not a good sign. This is especially true when it is combined with the view that the current Supreme Court is anti-patent. Taken together, this attitude reminds me of the bad old days, the days whose shadow we in this field have only recently emerged from: the days when patent lawyers huddled together, defensively, while a hostile world seemingly bent on the destruction of this area of law (and these incentives for inventors) lobbed random attacks their way.

Jeff Steck: Saving the Supreme Court from Folk Science

Based on the briefs filed in the Microsoft v. AT&T case, the Supreme Court faces a substantial risk of establishing logically indefensible precedent relating to computer software. The status of software in patent law is a fair subject of debate, but such policy decisions should not be based on folk science.

In the briefs now before the Court, software-and information generally-is characterized as an ethereal construct, barely capable of being controlled or understood. In its amicus brief, Autodesk calls information "meta-physical." The Software & Information Industry Association describes information as "purely intangible." According to Microsoft, information is "abstract," and is "floating in the ether." Information has been so denigrated that AT&T, who holds the patent on the software method relevant to the case, claims that "software is not 'information.'" 

Colloquially speaking, information is hardly a new concept. Perhaps this is why the briefs assume it is reasonable to use a dichotomy pulled from Aristotelian philosophy: optical disk as "substance" versus computer program as "accident." But like physics, chemistry, and other topics of interest to the ancients, information has become a science, and it should be discussed as a science.

Supreme Court: Licensee in Good Standing May File Declaratory Judgment

MedImmune v. Genentech (Supreme Court 2007).

Declaratory judgment (DJ) actions are often used by potential defendants to obtain a declaration that a patent is invalid, unenforceable, or not infringed.  Under Federal Circuit law, a licensee cannot challenge a patent without first breaching the license.  The CAFC's reasoning was that a licensee in good standing feels no apprehension of suit since the license is essentially a settlement between the parties. Without an apprehension of suit, the DJ action would not rise to an actual controversy as required by the Constitution.

In a broadly worded opinion, the Supreme Court has scrapped the Federal Circuit's "reasonable-apprehension" test on declaratory judgment standing in favor of a rule that allows licensee's in good-standing to file DJ actions.

We hold that petitioner was not required, insofar as Article III is concerned, to break or terminate its 1997 license agreement before seeking a declaratory judgment in federal court that the underlying patent is invalid, unenforceable, or not infringed.

There are several things to note immediately:

Not Limited to Patents: This case at least extends to all licensing issues and likely to most contracts -- whether or not they involve patents or intellectual property.

Suggested Contractual Work-Around: Reading between the lines, the opinion may indicate that a contractual "prohibition against challenging the validity of the patents." may serve to block challenges by licensee's in good standing. Without the clause, however, the Court found no such prohibition:

To begin with, it is not clear where the prohibition against challenging the validity of the patents is to be found. It can hardly be implied from the mere promise to pay royalties on patents

Regarding apprehension of suit, the Opinion's footnote 11 is a complete divergence from common practice -- finding that a licensee who pays royalties either in fear of an injunctions or for fear of treble damages is being coerced in a way that creates an Article III case or controversy.

Scalia's Hint on KSR

As you read this, keep in mind Michael Slonecker’s recent remark that “predictions are the musings of fools.” In late November, the Supreme Court heard oral arguments in KSR v. Teleflex — the case that will determine what constitutes a “nonobvious” invention. Then, last week, Justice Scalia briefly discussed the case at a meeting of technology business group and was quoted as saying: “I know how that one comes out, but I'm not going to tell you.”  What does Scalia’s quote mean? Perhaps nothing, but it might mean that the court has already come to a unanimous consensus on the case.

Microsoft v. AT&T: Transnational Patent Law At The Supreme Court

Microsoft v. AT&T (Supreme Court 2006)

Transnational patent law is a hot topic, and one the Supreme Court cannot ignore. The issue de jour involves the question of unauthorized export of patented software.  AT&T holds the speech compression patent that is infringed by Microsoft Windows. (RE 32,580). Microsoft exports the software code from Redmond to various international locations.  Once abroad, the code is then copied and installed in computers that are then sold abroad.  As the invention is claimed, the code alone does not infringe. Rather, infringement would only occur once the code is combined with the computer hardware. 

Under traditional notions of patent law, Microsoft’s actions are not infringement because the code alone does not infringe the patent, and (for the purposes of this case) the code is not combined with the hardware within the U.S. 

Here, however, traditional notions of territoriality have been supplanted by statute.  Under 35 U.S.C. 271(f), supply of only a portion of a component of a patented invention from the U.S. can be infringement.

35 U.S.C. 271(f) prohibits the “suppl[y] . . . from the United States . . . [of] all or a substantial portion of the components of a patented invention . . . in such manner as to actively induce the combination of such components outside of the United States,” as well as the “suppl[y] . . . from the United States [of] any component of a patented invention that is especially made or especially adapted for use in the invention.” 

Microsoft, of course, wants to avoid infringing the U.S. patent for its activity abroad and gives two separate reasons why its activity of exporting software do not fall within the parameters of 271(f). (I) Software code is an intangible string of information not a “component” as required by the statute. (II) Because copies of the code were used to create the infringing software/hardware combination, no physical particle that Microsoft exported actually became part of the finished product.  According to Microsoft, this means that nothing in the infringing combination was actually supplied from the U.S. as required by the statute. I term these two arguments the tangibility requirement and the molecular conservation requirement.

Microsoft and its supporters have now filed their merits briefs to the Supreme Court, and my reading of their arguments is that there is strong support for molecular conservation, but only weak support for tangibility. The Bush Administration supports this distinction in its brief filed jointly by the DOJ and PTO. 

On tangibility, the Government argues that software can certainly be a component, and that the statute is not limited to “only tangible components” as Microsoft suggests. Although not cited by the Government, Section 271(c) provides a statutorily distinct way of limiting components.  In referring to infringement through importation, that clause identifies only components of certain types of inventions such as machines and compositions.

On molecular conservation, the Government correctly notes that the statute requires that the exported components be the same components that are combined in the infringing manner. “Conduct that merely induces the combination of foreign-made components does not violate Section 271(f).” The statute, according to the Gov’t, leaves foreign manufacturers “free to manufacture and assemble copies of the identical components overseas” so long as none of the components actually assembled were made within the US.  Applying their argument to this case, we know that the software was copied and only those copies were combined with hardware in a would-be infringing manner.

A group of electronics companies led by Amazon filed a colorful brief that also supports the requirement of molecular conservation.

No matter where their unique arrangement was invented or dictated, if each molecule in the machine was supplied from outside the U.S., then no component was supplied from the U.S. In the present case, Microsoft did not supply even a single molecule of the foreign machines at issue.

Amazon also raises the slippery slope issue.  According to the brief, if Microsoft is liable here, then the Court would open the door to infringement for export of blueprints or a CAD/CAM design scheme.  That result, the brief argues, goes against congressional intent. As an aside, Amazon cited Wikipedia but did not include it in its list of “authorities.”  Although they do not cite it, the Pellegrini case holds that plans or instructions for a patented item cannot serve as components under 271(f).

In support of the molecular argument, a group of professors led by professors Lemley (Stanford) and Duffy (GWU), looked appropriately at the language of 271(f):

[A]s a matter of grammar that the phrase “such components” refers back to the components that have been “supplied” from United States. Thus, the plain language of the statute requires that inducing an extraterritorial combination constitutes an act of infringement if and only if the combined components are in fact the same components that were “supplied in or from” the United States.

For the professors, supplying exact copies does not meet the requirement. Most of the briefs come-up with some hypothetical metaphor to explain their situation — a guy memorizing some code and flying on an airplane, a hard-copy print out of some code that runs a fuel-injection system, CAD/CAM instructions, blueprints, etc.  The idea apparently is that if we allow copies of software to be considered components, then these situations necessarily also provide for infringement actions.  More accurately, however, they are just poor hypotheticals.

Software as Patentable Subject Matter: The anti-patent activist group SFLC led by Dan Ravicher and Eben Moglen also filed a brief that may be the dark-horse of this debate.  Their brief asks the Court to take a fresh look at the patentability of software.

Software can not be a “component[] of a patented invention” under 35 U.S.C. § 271(f) because software is not patentable subject matter under 35 U.S.C. § 101. As such, the Federal Circuit’s holding to the contrary in this case is erroneous and should be reversed.

It would be odd for the Court to decide the 101 issue in this case after dismissing LabCorp earlier this year.  However, I expect at least one concurring opinion supporting the ideas in this brief.

Impact on Software Industry: If Microsoft loses here, it will at least have a clear avenue to avoid future infringement. Unfortunately for US business, that avenue is to move all software development activities abroad so that components are never exported. This harmful effect was recognized and discussed in SIIA’s brief. SIIA is an industry group of software & technology companies who want to continue to design products in the US, but manufacture those products abroad. This argument is punctuated by BSA’s questionable hyperbole: “The purpose of patent protection is to encourage domestic innovation, not to drive it overseas.”

Impact in Biotech: Although not yet a viable industry, this could have a potentially large impact on biotechnology patent issues.  Like software, DNA code (or other biologics) could be shipped from the U.S. to be copied abroad and incorporated into an organism in an infringing manner.  Even more abstract, the export may merely involve transmitting a sequence listing that would be used to reproduce the sequence abroad.  Any decision on software should consider the potential impact on these areas as well.

Methods: What Professor Wegner has called the “Bizarre Twist” of this case involves the CAFC’s notion of export of components of method claims. In Union Carbide v. Shell, the court found that methods could indeed have components, and those included items used in the method (such as a catalyst).  Thus, in that case, the defendant could be held liable for exporting a stock catalyst if it intended to use the ingredient in a would-be infringing manner. Shell settled its case with Union Carbide, but has filed an amicus brief in this case, arguing that the Federal Circuit “seriously erred” by declaring that “every form of invention eligible for patenting falls within the protection of section 271(f).” 

Statutory Construction Excludes Methods?: Shell compares the use of the term “component” in 271(f) its use in 271(c) — the section addressing importation.  In 271(c), Congress explicitly limited components to “component[s] of a patented machine, manufacture, combination, or composition,” but also included a provision excluding importation of materials used in a patented process.  Shell’s argument: because 271(f) does not include the provision discussing materials used in a patented process, it cannot cover processes.  Of course, the unstated counter-argument to shell is that components discussed in 271(c) are specifically limited to components of machines, while 271(f) components are not so limited — indicating that “component” in 271(f) should receive a broader interpretation.

International Law: All of the transnational patent issues have an impact on international law issues. FICPI, a Swiss-based organization of patent folks filed its brief asking the the U.S. to keep its patents territorial and avoid stomping on the toes of others (as “young nations” are bound to do). FICPI’s implication that the Supreme Court is bound by the Paris Convention is plainly wrong.  The Paris Convention is not U.S. law. However, their point is well-taken, if 271(f) covers software, it thwarts the efforts of other countries to eliminate software patents.

Supreme Court: Current Test of Obviousness is "Gobbledygook"

KSR v. Teleflex (Supreme Court 2006, Oral Arguments).

The doctrine of nonobviousness is the cornerstone of American patent law.  I was reminded today by Phil Swain that our nonobviousness statute, section 103(a) of the Patent Act, was drafted by Judge Giles Rich.  Judge Rich is the most celebrated patent judge of this century.  His statutory masterpiece eliminated the amorphous concept of a “flash of genius” and replaced it with our now ubiquitous objective standard of a person having ordinary skill in the art.  In Graham v. John Deere, the Supreme Court reinforced 103(a) with its concept of case-by-case consideration of secondary indicia of nonobviousness as a way to avoid potential hindsight bias. 

Later, as the Federal Circuit developed its own patent jurisprudence, the court hit upon the teaching-suggestion-motivation test as another anti-hindsight rule.  That test requires evidence of some reason to combine various references that each teach part of an invention.  Thus, if there is no evidenced reason to combine the references, then the invention will be deemed nonobvious. The test, known by acronymists as “TSM,” has been labeled as a poster-child for bad patent behavior.  According to opponents of the test, the bright-line test makes patents too easy to obtain — resulting in a glut of patents covering trivial improvements. Those patents, in turn, hold-up industry research and greatly increase transaction costs and legal fees. 

In KSR v. Teleflex, the Supreme Court is questioning whether the TSM test should exist as the sole determinant of obviousness.  Question presented:

Whether the Federal Circuit has erred in holding that a claimed invention cannot be held ‘obvious’, and thus unpatentable under 35 U.S.C. § 103(a), in the absence of some proven “‘teaching, suggestion, or motivation’ that would have led a person of ordinary skill in the art to combine the relevant prior art teachings in the manner claimed.”

Until a few months ago, the common myth of the TSM test was that it required at least some hard evidence that provided at least a minimal reason to combine various prior art references.  It is that myth that provided the impetus for Supreme Court review. In recent months, however, we have learned that the CAFC’s version of the test allows for evidence that is implicit, based on common knowledge, found generally in the prior art as a whole, based simply on the nature of the problem or simple logic, or concluded by experts. See Kahn, Dystar, Ormco, Alza.  This jitterbug by the CAFC actually gives KSR much of what it wanted and smears the edges of the mythical bright-line rule.  Justice Scalia picked up on transition during oral arguments — noting that the recent cases leave the test “meaningless. [The CAFC] essentially said ‘our test simply reduces to what [KSR seeks] in this litigation.’ . . . this is gobbledygook. It really is, it’s irrational.” Justice Alito had a similar concern with the “new” TSM test:

J. Alito: “But what is the difference between asking whether something is implicit in the, in the prior art and simply asking whether it would have been obvious to a person of ordinary skill in the art?:

As discussed earlier on Patently-O, all the major patent bar associations filed briefs that support the current TSM test.  In a brilliant move, KSR neutralized those briefs by implying bias based on “the enormous fees that litigation of invalid patent claims can generate.” KSR Reply Brf. CJ Roberts appeared to buy-in to that analysis, joking that the filings “just indicate[] that this is profitable for the patent bar.” KSR Oral Arg.

One concern of the Court is whether modification of the obviousness doctrine would spoil long-settled rights.  The Justices, however, mentioned on several occasions that over the past year, the CAFC may have already upset any settled rights.

Mr Goldstein [for Teleflex]: “[The CAFC has had decades to look at this to try and elaborate a standard.”
J Breyer: “And it so quickly modified itself.”

Decision in February: Reports from the hearing noted that Justice who used the term “TSM” spoke with disdain and were highly critical of the test.  Although oral arguments are always full of counterfactuals and wild theory testing, the level of criticism supports the conventional wisdom that the TSM test is likely to be eliminated as “the exclusive” test.  Cases will rather be decided on a case-by-case basis using the standards of Graham v. John Deere. Already issued patents will still be given a presumption of validity, although it will be difficult for some courts to do this with a straight face.  The new key to avoiding invalidity will be secondary indicia of nonobviousness. Look for a 9–0 decision in early February.

TSM is not Dead: Much of the oral argument was filled with an attempt to simply understand the TSM test, and to figure out what is meant by a “motivation.”  If they cannot figure-out the test, they would likely completely trash-it as unworkable. Of course, by the time the opinion is penned, they will understand the current test and the test will not be scrapped as a whole. Rather, they will follow the Government’s suggestion that TSM continue to be used as a “valid means of proving obviousness.” In addition, however, flexibility will be added to allow for other ways of determining nonobviousness.

Here are some quotes from oral arguments:

CJ Roberts: “[T]the Federal Circuit’s approach focuses . . . on prior art — as opposed to, I would say, common sense.” 

J Scalia: “And in the last year or so, after we granted cert in this case after these decades of thinking about [the obviousness doctrine, the CAFC] suddenly decides to polish it up.”

J. Breyer: “I’ve read it about 15 or 20 times now, I just don’t understand what is meant by the term ‘motivation.’”

Mr. Hungar [for US Gov’t]: “Construed as the sole means of proving obviousness the teaching suggestion motivation test is contrary to the Patent Act, irreconcilable with this Court's precedents and bad policy. It asks the wrong question and in cases like this one, it produces the wrong answer. It should be rejected and the judgment of the Court of Appeals should be reversed. . . . It’s just foreign to this Court’s precedents as a mandatory prerequisite for obviousness.”

Mr. Dabney [for KSR]: “[T]here is no legal regime that is a greater generator of patent litigation than the teaching suggestion motivation test that is urged by the respondent.” [DDC: Is this true?].

In Fractured Decision, CAFC Refuses to Reexamine De Novo Claim Construction

Amgen v. HMR (CAFC en banc denial)

Cybor is the much reviled CAFC decision holding that the construction of patent claim language is a question of law that is reviewed de novo — without any regard to the lower court’s reasoning or ruling.  The Cybor rule is believed by many to have dramatically increased uncertainty in patent litigation as well as likelihood of appeal.  Importantly, the associated reversal rate also demoralizes district court judges who already often struggle with the technical and legal complexity of patent cases.

In Amgen, the appellate panel reviewed construction of the term “therapeutically effective amount” of erythropoietin and, in the process illustrated how Cybor gives the court a “capacity for arriving at its own idiosyncratic construction.” (Quoting Prof. Kevin Noonan). Here, the CAFC panel reversed the lower court’s construction based on its interpretation of the specification. 

HMR’s request for rehearing en banc has been denied, but a contingent of six separate dissenting and concurring opinions show the internal conflict.

Chief Judge Michel, who also dissented from the original panel decision, led the charge against Cybor. “I have come to believe that reconsideration is appropriate and revision may be advisable.”  CJ Michel, who was joined in the opinion by J Rader, cited four practical reasons for eliminating de novo review:

1. High reversal rate;
2. Lack of predictability of outcomes — something that decreases settlement and frustrates lower courts;
3. The disregard of time spent by district court judges in understanding the evidence and patent information;
4. The mind-numbing minutia of claim construction decisions faced by the court in “nearly every patent case.”

Claim construction, although similar to statutory construction is different for many reasons and is intertwined with facts that make the foundation for de novo review questionable. The arguments of CJ Michel are further highlighted by Judge Newman’s dissent.

J Newman focuses on how scientific and technological evidence serve as the backdrop for any claim construction and how claim construction should focus on the invention rather than following formalistic requirements that trip over every statement in a patent application. Finally, Newman argues that a Daubert framework is more appropriate for claim construction.

The Federal Circuit's position that patent interpretation requires more rigorous appellate review than other fact/law issues has not well withstood the test of experience. It is time to reopen the question and to rethink, en banc, the optimum approach to accuracy, consistency, and predictability in the resolution of patent disputes, with due attention to judicial structure, litigants' needs, and the national interest in invention and innovation. (Newman dissenting).

Judge Rader agreed with both CJ Michel and J Newman, but filed his own opinion. Rader gave some legal basis for reviewing Cybor — noting the Supreme Court’s opinion that claim construction "falls somewhere between a pristine legal standard and a simple historical fact." (Markman). Rader maintained his long-standing position that district courts should be given deference because they are better versed in the facts and the issues.

“Trial judges can spend hundreds of hours reading and rereading all kinds of source material, receiving tutorials on technology from leading scientists, formally questioning technical experts and testing their understanding against that of various experts, examining on site the operation of the principles of the claimed invention, and deliberating over the meaning of the claim language. If district judges are not satisfied with the proofs proffered by the parties, they are not bound to a prepared record but may compel additional presentations or even employ their own court-appointed expert." (Rader dissenting in Cybor).

Judge Moore: In what appears to be her first patent opinion, New CAFC Judge Moore also set her target on Cybor — stating that the court should “reconsider its position on deference.” 

Judges Gajarsa, Linn, and Dyk all concurred with the decision not to rehear this particular case, but noted that “In an appropriate case we would be willing to reconsider limited aspects of the Cybor decision.”  In particular, those three judges appear to believe that de novo is still appropriate when the intrinsic evidence (written description and prosecution history) on its face resolves “the question of claim interpretation.”

SUPREME COURT NEXT: This leaves us in the situation where at least eight of the twelve Federal Circuit judges believe that Cybor should be revisited if an “appropriate case” arises. This fractured decision is also ripe for Supreme Court review, and along with the Tamoxifen antitrust cases, are the two most likely to be granted certiorari in 2007.

Details: Judges Michel, Newman, Rader, Mayer, and Moore have all bluntly criticized Cybor. Judges Gajarsa, Linn, and Dyk have a more limited criticism.

KSR Shifts Obviousness Debate to "Mere Aggregations" and Presumptions of Non-Obviousness

KSR v. Teleflex (Supreme Court 2006).

Section 103 of the Patent Act focuses on “differences between the subject matter sought to be patented and the prior art.”  In the 1976 Sakraida case, the Supreme Court held that simply aggregating old elements together does not pass the patentability test if the elements are each performing the same functions that they were already known to perform.

The “mere aggregation” test of Sakraida, however, has not been followed by the Court of Appeals for the Federal Circuit (CAFC). Instead, the CAFC’s approach has allowed mere aggregations to be patented so long as there is no evidence suggesting that the elements be combined.

The pending case of KSR v. Teleflex squarely addresses this debate. KSR recently filed reply brief closes the written arguments in this landmark case, and oral arguments are scheduled for November 28, 2006.

KSR’s attorneys, including GWU Professor John Duffy, argue strongly that 103(a) has been wrongly interpreted as merely a way to challenge patentability rather than a “condition of patentability” as the section is titled. Under the current suggestion test, claims “cannot be held invalid . . . no matter how trivial might be the differences” from the prior art unless evidence suggesting the difference is found in the art.  As noted by Hal Wegner, the Court’s reaction to this argument could shift the strong presumptions of non-obviousness.

KSR has gone beyond its attack on the Federal Circuit suggestion/teaching/motivation test and raised as a further issue the point that it should win under a preponderance of the evidence standard for challenging patent validity.

In the process, KSR takes a shot at the AIPLA’s “balanced” position.

It is by no means clear why patent bar groups would have a systematic interest in a “balanced” standard of patentability, in view of the enormous fees that litigation of invalid patent claims can generate.

KSR v. Teleflex: In Support of the Status Quo

 KSR v. Teleflex (Supreme Court 2006).

By Dennis Crouch [dcrouch@gmail.com]

Background: Teleflex and its supporters have now filed their briefs in defense of the Federal Circuit’s methodology for determining whether a patent is “obvious.” [Copies of briefs are provided below]. The doctrine of nonobviousness is fundamental to our patent system.  In order to be eligible for a patent an invention must be both novel and non-obvious.  Novelty is generally narrowly applied to cases where the invention is identical to something already in the public domain.  Obviousness, however, is a more difficult beast and is intended to ensure that patent rights are only granted to inventions that move us a significant distance past the prior art. 

Obviousness has always been a “squishy” term, but over the past twenty-five years, the Court of Appeals for the Federal Circuit has developed a somewhat objective nonobviousness doctrine using a teaching/suggestion/motivation (TSM) test. According to the test, when various pieces of prior art each contain elements of an invention, the prior art can be combined together to invalidate a patent on the invention only when there is some motivation, suggestion, or teaching to combine the prior art. One problem with any obviousness test is hindsight bias. It is all-to-easy to look-back and assert that an invention would have been obvious. One purpose of the objective TSM test is to avoid this type of hindsight bias.

KSR has asked the Supreme Court to rethink that approach and take a fresh look at the obviousness standard for patentability. The petition questions whether obviousness should require any proof of some suggestion or motivation to combine prior art references.

Question Presented: Whether the Federal Circuit erred in holding that a claimed invention cannot be held "obvious," and thus unpatentable under 35 U.S.C. sec. 103(a), in the absence of some proven "'teaching, suggestion or motivation' that would have led a person of ordinary skill in the art to combine the relevant prior art teachings in the manner claimed"?

Interestingly, the Supreme Court has not heard an obviousness since well before the founding of the Federal Circuit. In that case (Sakraida 1976), the Court held that a combination which only unites old elements with no change in their respective functions is precluded from patentability under 103(a).  Under the Sakraida standard, the Teleflex patent is arguably obvious.  In an article several years ago, Professor John Duffy identified this obviousness issue as one that should attract the Supreme Court’s attention.

[The Federal Circuit’s suggestion] test, which tends to make even seemingly trivial developments patentable, is entirely the Federal Circuit’s product.  It has no basis in the Supreme Court’s case law and may, in fact, be inconsistent with the Court’s most recent pronouncement on the subject (though that precedent is now more than a quarter century old).

Duffy, The Festo Decision and the Return of the Supreme Court to the Bar of Patents, 2002 S.Ct. Rev. 273, 340-41 (2003).  Now, Duffy, a former clerk of Justice Scalia, is part of the KSR team that is trying to change the rule of law. The KSR case itself concerns a patent covering a gas pedal for an automobile. KSR makes pedals for GM & Chevy trucks and was sued for infringement of the Teleflex patent.

A discussion of briefs in support of the petitioner are found here: Discussion of Breifs Supporting Petitioner.

What follows is a discussion of briefs in support of the respondent: (i.e., in support of the status quo).

Respondent Teleflex: Brief on the Merits

Settled Law: Respondent begins with a compelling exposition on the power of stare decisis. “Millions of patents” have issued based on the suggestion test, and modifying that test would in Hal Wegner’s words, “threaten the validity of literally hundreds of thousands of existing patents still in force.”

Non-Rigid Test: Respondent defines the suggestion test as a “flexible [test that] looks to any available indication that a practitioner in the art would have had some reason to select the elements of the invention from among the prior art and combine them in the manner claimed by the invention.”  Relying heavily on the CAFC’s very recent obviousness pronouncements of Dystar and Alza, the brief points out that a suggestion does not need to be found in prior art, but rather can be implicit in the nature of the problem, customer demand, similarity between references, knowledge of PHOSITA, wide knowledge of value of feature to be combined, etc.  [DDC: Query whether the broad application of implicit suggestions would constructively eliminate the rule.]

The suggestion test can be contrasted with the “synergy” test proposed by petitioner and the “extraordinary level of innovation” test from the Solicitor General. Those approaches essentially mirror the pre-103 requirement of an “invention.” According to Judge Rich, “The first policy decision underlying Section 103 was to cut loose altogether from the century-old term ‘invention.’”

Intellectual Property Owners Association (IPO) in Support of Respondent:

The IPO is an organizatoin of intellectual property owners. MBHB (where I am of counsel) filed the brief on behalf of IPO. IPO’s brief supports the motivation requirement as an objective but flexible and practical approach to the obviousness problem.  IPO hits on the hindsight problem:

[The test must rely on] objective evidence, not mere unsupported opinion or argument. Otherwise, the inevitable use of hindsight will tend to render meritorious inventions "obvious" by using the inventor’s own teachings as a roadmap to piece together prior art references in ways that would not have been obvious at the time of the invention.

IPO also takes-issue with any “synergy” requirement. Synergy occurs when the "the interaction of elements that when combined produce a total effect that is greater than the sum of the individual elements." There are many patent-worthy inventions, however, that lack true synergy. In addition, the Solicitor General’s proposed "extraordinary level of innovation" requirement goes too far. “Nothing in the patent statute suggests that patents should only be awarded to Nobel laureates.”

Paul Berghoff, Jeremy Noe, and Aaron Barkoff (of OrangeBookBlog) are on the brief.

American Intellectual Property Law Association (AIPLA) in Support of Respondent:

AIPLA’s brief is a fun read — it starts off with quotes from Billy Wilder and King Solomon, both of which give us pause on the question of hindsight.

What has been is what will be,
and what has been done is what will be done;
there is nothing new under the sun.

According to AIPLA, King Solomon wasn’t so wise — perhaps because his vision of the past was colored by hindsight. The CAFC’s test of obviousness is useful because it helps avoid hindsight.

TSM is a well-established, thoughtfully-analytic framework that provides certainty and uniformity in obviousness determinations while allowing proper flexibility. By requiring a showing of why someone of ordinary skill in the relevant art would think the invention obvious, it functions as a critical evidentiary device that prevents arbitrary decisions driven by hindsight.

As is typical of opposition briefs, the AIPLA correctly notes that the CAFC’s suggestion test does not require that the suggestion be explicit or written.

I can concieve of a strong [and thus far unstated] argument that it would be sensible to require that the suggestion be written and explicit.  At this point in history, we have more people writing than ever before and those people are each writing more than earlier writers. At the same time, search costs are dropping dramatically and will continue to drop. In this scenario, why would we need to allow the evidentiary nightmare of giving weight to previously unstated suggestions to find an invention obvious?

Professor Thomas Field of Franklin Pierce in Support of Respondent:

Professor Field looks at the CAFC and its role in the patent process.  Unlike its predecesor CCPA, the CAFC hears both administrative patentability and litigation based cases. That means that the CAFC must “confront the consequences of unwaranted grants.” 

If the problem is the grant of too-many patents, the CAFC has little to say there because the court has no role in granting patents except to occasionally rule that the BPAI’s bases for rejection are unsupported.

Pre- and post-grant opposition proceedings may be the answer, but those decisions are for Congress.

ABA in Support of Respondent:

ABA amicus briefs are always difficult to obtain becauase they need the support of both the IP Section and the entire ABA House of Delegates.  Here, the way to consensus was not to argue that the TSM test is the best test, but rather to note that it is useful, objective, and deeply rooted in the Supreme Court’s John Deere jurisprudence. In addition, the test is well settled, and messing with the test would have a far-reaching and complex impact on the economy and state of innovation.

If some elusive method not based on evidence were to be substituted for the present inquiry, hundreds of thousands of patents granted under the teaching-suggestion-motivation methodology would be immediately placed under a cloud.

Harold Milton in Support of Respondent:

Harold Milton drafted the claims being asserted by Teleflex and has filed a very interesting brief in support of Teleflex.  Interesting because he begins with a statement that the suggestion test is illusory, or at least a misnomer. There is no requirement that there be any specific statement of suggestion in the prior art. Nonetheless, the test is important to maintain an “objective standard of patentability” and “consistent evaluation.”  It also prevents chaos:

Without an objective standard, chaos would be multiplied across thousands of patent examiners, judges, juries, attorneys, etc. and would result in inconsistent decisions on patentability.

According to Milton, the Court should reject the suggestion test and stick to its prior decisions that obvious is found when there is a “mere selection of prior art elements combined to perform the identical function as they did separately in the prior art.”

Lee Thomason in Support of Respondent:

Thomason is a Kentucky-based patent attorney. One interesting aspect of his argument involves the law/equity distinction.  According to Thomason, challenges to validity are equitable in their origins as evidenced both by the recited equitable factors of 103(a) (“as a whole”) and by Blackstone’s recitation of the writ fo scire facias. As such, any changes to the rule should be to review obviousness decisions “according to the standard applied to equitable rulings.” Equitable review requires a full discussion of the record and results in more predictability.

 KSR v. Teleflex (Supreme Court 2006).

By Dennis Crouch [dcrouch@gmail.com]

By Dennis Crouch [dcrouch@gmail.com]

Background: Teleflex and its supporters have now filed their briefs in defense of the Federal Circuit’s methodology for determining whether a patent is “obvious.” [Copies of briefs are provided below]. The doctrine of nonobviousness is fundamental to our patent system.  In order to be eligible for a patent an invention must be both novel and non-obvious.  Novelty is generally narrowly applied to cases where the invention is identical to something already in the public domain.  Obviousness, however, is a more difficult beast and is intended to ensure that patent rights are only granted to inventions that move us a significant distance past the prior art. 

Obviousness has always been a “squishy” term, but over the past twenty-five years, the Court of Appeals for the Federal Circuit has developed a somewhat objective nonobviousness doctrine using a teaching/suggestion/motivation (TSM) test. According to the test, when various pieces of prior art each contain elements of an invention, the prior art can be combined together to invalidate a patent on the invention only when there is some motivation, suggestion, or teaching to combine the prior art. One problem with any obviousness test is hindsight bias. It is all-to-easy to look-back and assert that an invention would have been obvious. One purpose of the objective TSM test is to avoid this type of hindsight bias.

KSR has asked the Supreme Court to rethink that approach and take a fresh look at the obviousness standard for patentability. The petition questions whether obviousness should require any proof of some suggestion or motivation to combine prior art references.

Question Presented: Whether the Federal Circuit erred in holding that a claimed invention cannot be held "obvious," and thus unpatentable under 35 U.S.C. sec. 103(a), in the absence of some proven "'teaching, suggestion or motivation' that would have led a person of ordinary skill in the art to combine the relevant prior art teachings in the manner claimed"?

Interestingly, the Supreme Court has not heard an obviousness since well before the founding of the Federal Circuit. In that case (Sakraida 1976), the Court held that a combination which only unites old elements with no change in their respective functions is precluded from patentability under 103(a).  Under the Sakraida standard, the Teleflex patent is arguably obvious.  In an article several years ago, Professor John Duffy identified this obviousness issue as one that should attract the Supreme Court’s attention.

[The Federal Circuit’s suggestion] test, which tends to make even seemingly trivial developments patentable, is entirely the Federal Circuit’s product.  It has no basis in the Supreme Court’s case law and may, in fact, be inconsistent with the Court’s most recent pronouncement on the subject (though that precedent is now more than a quarter century old).

Duffy, The Festo Decision and the Return of the Supreme Court to the Bar of Patents, 2002 S.Ct. Rev. 273, 340-41 (2003).  Now, Duffy, a former clerk of Justice Scalia, is part of the KSR team that is trying to change the rule of law. The KSR case itself concerns a patent covering a gas pedal for an automobile. KSR makes pedals for GM & Chevy trucks and was sued for infringement of the Teleflex patent.

A discussion of briefs in support of the petitioner are found here: Discussion of Breifs Supporting Petitioner.

What follows is a discussion of briefs in support of the respondent: (i.e., in support of the status quo).

Respondent Teleflex: Brief on the Merits

Settled Law: Respondent begins with a compelling exposition on the power of stare decisis. “Millions of patents” have issued based on the suggestion test, and modifying that test would in Hal Wegner’s words, “threaten the validity of literally hundreds of thousands of existing patents still in force.”

Non-Rigid Test: Respondent defines the suggestion test as a “flexible [test that] looks to any available indication that a practitioner in the art would have had some reason to select the elements of the invention from among the prior art and combine them in the manner claimed by the invention.”  Relying heavily on the CAFC’s very recent obviousness pronouncements of Dystar and Alza, the brief points out that a suggestion does not need to be found in prior art, but rather can be implicit in the nature of the problem, customer demand, similarity between references, knowledge of PHOSITA, wide knowledge of value of feature to be combined, etc.  [DDC: Query whether the broad application of implicit suggestions would constructively eliminate the rule.]

The suggestion test can be contrasted with the “synergy” test proposed by petitioner and the “extraordinary level of innovation” test from the Solicitor General. Those approaches essentially mirror the pre-103 requirement of an “invention.” According to Judge Rich, “The first policy decision underlying Section 103 was to cut loose altogether from the century-old term ‘invention.’”

Intellectual Property Owners Association (IPO) in Support of Respondent:

The IPO is an organizatoin of intellectual property owners. MBHB (where I am of counsel) filed the brief on behalf of IPO. IPO’s brief supports the motivation requirement as an objective but flexible and practical approach to the obviousness problem.  IPO hits on the hindsight problem:

[The test must rely on] objective evidence, not mere unsupported opinion or argument. Otherwise, the inevitable use of hindsight will tend to render meritorious inventions "obvious" by using the inventor’s own teachings as a roadmap to piece together prior art references in ways that would not have been obvious at the time of the invention.

[The test must rely on] objective evidence, not mere unsupported opinion or argument. Otherwise, the inevitable use of hindsight will tend to render meritorious inventions "obvious" by using the inventor’s own teachings as a roadmap to piece together prior art references in ways that would not have been obvious at the time of the invention.

IPO also takes-issue with any “synergy” requirement. Synergy occurs when the "the interaction of elements that when combined produce a total effect that is greater than the sum of the individual elements." There are many patent-worthy inventions, however, that lack true synergy. In addition, the Solicitor General’s proposed "extraordinary level of innovation" requirement goes too far. “Nothing in the patent statute suggests that patents should only be awarded to Nobel laureates.”

Paul Berghoff, Jeremy Noe, and Aaron Barkoff (of OrangeBookBlog) are on the brief.

American Intellectual Property Law Association (AIPLA) in Support of Respondent:

AIPLA’s brief is a fun read — it starts off with quotes from Billy Wilder and King Solomon, both of which give us pause on the question of hindsight.

Harold Milton drafted the claims being asserted by Teleflex and has filed a very interesting brief in support of Teleflex.  Interesting because he begins with a statement that the suggestion test is illusory, or at least a misnomer. There is no requirement that there be any specific statement of suggestion in the prior art. Nonetheless, the test is important to maintain an “objective standard of patentability” and “consistent evaluation.”  It also prevents chaos:

Without an objective standard, chaos would be multiplied across thousands of patent examiners, judges, juries, attorneys, etc. and would result in inconsistent decisions on patentability.

Lee Thomason in Support of Respondent:

Thomason is a Kentucky-based patent attorney. One interesting aspect of his argument involves the law/equity distinction.  According to Thomason, challenges to validity are equitable in their origins as evidenced both by the recited equitable factors of 103(a) (“as a whole”) and by Blackstone’s recitation of the writ fo scire facias. As such, any changes to the rule should be to review obviousness decisions “according to the standard applied to equitable rulings.” Equitable review requires a full discussion of the record and results in more predictability.

Petitions Stage

PTO's Refusal to Register Temporary Aliens Moves Toward Supreme Court Hearing

Lacavera v. Dudas (on Petition for Certiorari).

Catherine Lacavera is an attorney admitted to practice in New York, Massachusetts, and before the Supreme Court of the United States.  She has litigated patent cases in Federal Courts, drafted patent applications, passed the PTO registration examination, and now is an attorney for Google in California. Unfortunately for Ms. Lacavera, she is Canadian and does not hold a green card.  (Lacavera holds a non-immigrant work visa). 

Under USPTO rules, Lacavera’s “nonimmigrant status is ‘inconsistent’ with [PTO] registration because [the nonimmigrant status] is limited in time and scope whereas registration is not so limited.”  The CAFC agreed with the PTO in denying Lacavera her full registration, and Lacavera has now petitioned the Supreme Court for a writ of certiorari.

The petition presents three questions:

 1. Does the USPTO . . . have the authority to refuse to register nonimmigrant aliens as patent practitioners solely on the basis of their immigration status, where the nonimmigrant aliens are otherwise qualified for registration and authorized by United States Citizenship and Immigration Services ("USCIS") to practice as patent practitioners in the United States?

 2. Did the Federal Circuit, in upholding a USPTO rule denying registration to nonimmigrant aliens, inappropriately apply only a "rational review" standard where it should have applied at least "heightened scrutiny," if not "strict scrutiny," to a federal agency rule that discriminates against nonimmigrant aliens without serving any special national interest?

3. Do bar admission rules, such as the state rule that is before this Court in Leclerc v. Webb and Wallace v. Calogero, and the federal rule that is the basis of this case, that deny aliens lawfully within the United States access to employment opportunities based on the duration and employment restrictions of their current visas, violate the aliens' rights to "equal protection" in the absence of any evidence that the visa restrictions relate to valid state or federal interests in ensuring competency of practitioners?

On the issue of equal protection, Lacavera argues that the CAFC “set a dangerous precedent” by denying equal protection because “the USPTO treats all nonimmigrant alien's the same by refusing to register any of them. Equal discrimination is not equal protection.”

Interestingly, because she is Canadian and a U.S. attorney, Lacavera is the perfect test case.  If she were residing in Canada, the PTO would permit her registration even without any U.S. immigration status.  Additionally, her visa specifically authorizes her to practice as a patent attorney in the U.S.

The Coalition of Service Industries has filed a brief in support of the petition — arguing that we should open our doors to legally admitted temporary residents as a bargaining chip for reciprocity.

The U.S. has for example asked many other nations not to discriminate against American lawyers who provide or wish to provide legal services in foreign countries. Because reciprocity plays a large role in trade negotiations, the USPTO rule adversely affects our legal community in the several important trade negotiations that are currently underway or planned.

The Supreme Court has expressed its interest in the case — requesting that the government file a responsive brief by November 1, 2006.

Notes:

• Interestingly, soon after Lacavera filed her petition for certiorari, her application for permanent residence was granted.  The PTO may end up mooting this issue by granting her full registration.

Supreme Court Likely to Hear Transnational Patent Law Dispute

Microsoft v. AT&T (on petition for certiorari).

The DOJ and PTO have given their solid support to Microsoft’s petition for certiorari in its battle over transnational patent infringement. This support makes grant of the petition highly likely.

This case, like Eolas and Pellegrini before, questions the scope of Section 271(f) of the Patent Act.  That statute allows a U.S. patentee to collect damages for foreign sales of a patented invention based on the export of one or more of its components from the U.S.  Recently, the CAFC has expanded the common interpretation of the statute to include the export of software code (AT&T, Eolas) as well as to the export of elements used in a patented method (Union Carbide).  In a case that is difficult to square with AT&T or Eolas, the court held that the “component” does not apply to plans or instructions.

In this case, Microsoft’s software code was generated in the U.S. and then shipped abroad where copies were then generated and distributed.  AT&T claims (and courts have thus far agreed) that sales of those foreign copies infringe the U.S. patent and create liability.  The chart below gives my loose graphical interpretation of the events.

If it stands, this case could have far-reaching effects in the fields of biotechnology (DNA/cell replication) as well as foreign piracy (shipping product from the U.S. to reverse engineer and copy in a foreign country).

From a business perspective, this interpretation of the statute gives business executives another reason to send software jobs overseas.  If the component was not exported from the U.S., there will be no damages under 271(f).

In their brief supporting the petition, Daryl Joseffer and the DOJ crew agree that software can be a component of a patented invention.  They argue, however, that the foreign replicas do not create liability under the act because the replicas themselves were not supplied from the United States (as is required by the statute). According to the brief, the lower court’s interpretation “improperly extends United States patent law to foreign markets and puts United States software companies at a competitive disadvantage vis-a-vis their foreign competitors in foreign markets.”

The Government argues that the extraterritorial nature of U.S. patents should be narrowly construed and that if someone wants rights to stop foreign infringement, then they should get foreign patents.

Respondent’s remedy lies in obtaining and enforcing foreign patents, not in attempting to extend United States patent law to overseas activities.

Important recent 271(f) cases:

• NTP v. Research in Motion, (271(f) “component” would rarely if ever apply to method claims).
• AT&T v. Microsoft, 414 F.3d 1366 (Fed. Cir. 2005) (271(f) “component” applies to method claims and software being sold abroad);
• Eolas v. Microsoft, 399 F.3d 1325 (Fed. Cir. 2005) (271(f) “component” applies to method claims and software);
• Pellegrini v. Analog Devices, 375 F.3d 1113 (Fed. Cir. 2004) (271(f) “component” does not cover export of plans/instructions of patented item to be manufactured abroad);
• Bayer v. Housey Pharms, 340 F.3d 1367 (Fed. Cir. 2003) (271(g) “component” does not apply to importation of ‘intangible information’).

Zoltek Patent Takings Rehearing Denied: No Fifth Amendment Protection

Zoltek v. U.S. (Fed. Cir. 2006, en banc denied).

Just last week, Patently-O highlighted Professor Mossoff’s historical analysis of patent-takings jurisprudence.  That article took the CAFC to task for its continuation of the untrue myth that “patents were never secured as constitutional private property in the nineteenth century.”  In fact, argues Mossoff, “nineteenth-century courts applied the Takings Clause to patents, securing these intangible property rights as constitutional private property.” “It is time to set the historical record straight.”

Mossoff’s article was prompted by the April 2006 decision in Zoltek v. U.S. In that case, the CAFC found itself bound by the 1894 case of Schillinger v. United States where the Supreme Court ruled that a patent holder could not sue the government for patent infringement as a Fifth Amendment taking.

In Schillinger v. United States, 155 U.S. 163 (1894), the Supreme Court rejected an argument that a patentee could sue the government for patent infringement as a Fifth Amendment taking under the Tucker Act. Schillinger remains the law.

 With a petition for rehearing, Zoltek gave the CAFC another shot.

Without opinion (as is usual in denials), the petition for rehearing was denied.  However, two opinions were released.  Judges Dyk and Gajarsa filed a concurring opinion arguing first that there is no need for a taking claim because private parties already have a right to sue the government for unauthorized patent infringement under 28 U.S.C. § 1498. Second, the two judges argue that because patent rights are created by relatively recent federal statute, it is difficult to characterize limitations of those rights as a “taking of established property rights.”  

In dissent, Judge Newman laid out the holding in simple terms:

The panel majority holds that there is no jurisdiction [in any court] of a Takings claim for compensation for unauthorized use by the government of a patented invention. This ruling is contrary to decision, statute, policy, and constitutional right. I must, respectfully, dissent from the court's endorsement of this ruling.

 Judge Newman finds that the majority decision only makes sense if we reject the premise that patents are property.

Supreme Court Next: Judge Newman’s set this case up nicely for Supreme Court review on the issue of takings and more broadly what is meant by intellectual property.

Inequitable Conduct: Ferring Asks for Supreme Court Review

Ferring v. Barr (on petition for certiorari).

In February 2006, the CAFC affirmed a lower court ruling that Ferring’s patent was unenforceable due to inequitable conduct.  During prosecution some 15 years earlier, Ferring had submitted several non-inventor declarations to support patentability, but did not disclose to the PTO that the some of the declarants had been paid consultants for the patentee in the past. Of course, this information was not requested by the PTO. Nonetheless, the CAFC found that the patentee’s non-disclosure created a material potential for bias because the “witness’s interest is always pertinent to his credibility” and that the intent could be inferred from the negligence in failing to disclose.

Judge Newman penned a strong dissent in the case, arguing that the decision revives “reviving the culture of attack on inventor rights and attorney reputations based on inference and innuendo.”

My colleagues, endorsing several novel and unsupportable presumptions of wrongdoing, do injury to the reasonable practice of patent solicitation, even as they defy the rules of summary judgment.

Now, Ferring (along with its co-plaintiff Aventis) has filed a petition for certiorari, requesting that the Supreme Court hear the case — asking whether the CAFC improperly lowered the standards for materiality and intent in its finding of inequitable conduct.

Supreme Court: MedImmune v. Genentech

The CAFC has held on a number of occasions that a current licensee has no standing to sue for declaratory judgment because there is no immediate threat of being sued for patent infringement.  However, this conclusion pushes against the Supreme Court’s 1969 decision in Lear v. Adkins which held that a public policy interest in invalidating bad patents was strong enough to warrant a limitations on a licensee’s ability to give up its right to challenge a patent’s validity.  After MedImmune, a licensee, is appealing the dismissal of its DJ action and has presented the following question to the Supreme Court for review:

Does Article III’s grant of jurisdiction of "all Cases . . . arising under . . . the Laws of the United States," implemented in the "actual controversy" requirement of the Declaratory Judgment Act, 28 U.S.C. § 2201(a), require a patent licensee to refuse to pay royalties and commit material breach of the license agreement before suing to declare the patent invalid, unenforceable or not infringed?

Briefs are all in and oral arguments are scheduled for October 4, 2006.

The potential impact of this case should not be underestimated. A license agreement is generally thought of as a settlement of a dispute.  If MedImmune is right, however, an ongoing license agreement could actually be a litigation ticket.

DDC's Two comments:

• Although I didn't file a brief, I agree with much of the analysis of the two law professor briefs in support of the Respondent (Hricik & Cotter).  In general, however, what's wrong with Professor Epstein's free-market approach -- allowing validity challenges be a negotiated contract term.  Although the public has a strong interest in mooting invalid patents, it is rare a licensed patent has only one potential licensee and we now have a number of public interest organizations that are becoming experts of challenging bad patents through reexamination and litigation.
• Post Lear decisions are a mess. Hopefully the Court will at least use this case as a vehicle for clarifying the law.

KSR v. Teleflex: Rethinking Obviousness

KSR v. Teleflex (Supreme Court 2006).

By Dennis Crouch

The first round of briefs have now been filed in the much anticipated KSR case that will address fundamental questions of patentability. [Copies of briefs are found below] The doctrine of nonobviousness ensures that patent rights are not granted on inventions that are simply throw-away modifications of prior technology.  Questions of obviousness are at play in virtually every patent case, in both proceedings before the USPTO and during infringement litigation.

Obviousness has always been a “squishy” term, but over the past twenty-five years, the Court of Appeals for the Federal Circuit has developed a somewhat objective nonobviousness doctrine using a teaching/suggestion/motivation (TSM) test. According to the test, when various pieces of prior art each contain elements of an invention, the prior art can be combined together to invalidate a patent on the invention only when there is some motivation, suggestion, or teaching to combine the prior art.

KSR has asked the Supreme Court to rethink that approach and take a fresh look at the obviousness standard for patentability. The petition questions whether obviousness should require any proof of some suggestion or motivation to combine prior art references.

Question Presented: Whether the Federal Circuit erred in holding that a claimed invention cannot be held "obvious," and thus unpatentable under 35 U.S.C. sec. 103(a), in the absence of some proven "'teaching, suggestion or motivation' that would have led a person of ordinary skill in the art to combine the relevant prior art teachings in the manner claimed"?

Interestingly, the Supreme Court has not heard an obviousness since well before the founding of the Federal Circuit. In that case (Sakraida 1976), the Court held that a combination which only unites old elements with no change in their respective functions is precluded from patentability under 103(a).  Under the Sakraida standard, the Teleflex patent is arguably obvious.  In an article several years ago, Professor John Duffy identified this obviousness issue as one that should attract the Supreme Court’s attention.

[The Federal Circuit’s suggestion] test, which tends to make even seemingly trivial developments patentable, is entirely the Federal Circuit’s product.  It has no basis in the Supreme Court’s case law and may, in fact, be inconsistent with the Court’s most recent pronouncement on the subject (though that precedent is now more than a quarter century old).

Duffy, The Festo Decision and the Return of the Supreme Court to the Bar of Patents, 2002 S.Ct. Rev. 273, 340-41 (2003).  Now, Duffy, a former clerk of Justice Scalia, is part of the KSR team that is trying to change the rule of law.

The case itself concerns a patent covering a gas pedal for an automobile. KSR makes pedals for GM & Chevy trucks and was sued for infringement of the Teleflex patent.

Crouch’s notes: In my view, the question is not correctly presented because it focuses on the aspect of “proof.” Of course any decision on obviousness should be based on some sort of proof. I expect that the Court will, as they often do, ignore this particular question and instead answer the broader question of how “a court should go about deciding whether matter claimed in a patent should be deemed ‘non-obvious' subject matter.”  In fact, in its merits brief, KSR implicitly recognizes this more fundamental question in its summary of the case.

It is very likely that the Federal Circuit’s home-grown TSM test will be eliminated.  This leaves us with a gaping hole — the most likely successor is a return to Sakraida that would require a showing of some functional-shift caused by a combination of old elements. 

Petitioner KSR and a group of amici have recently filed their briefs on the merits.  Looking at the Amici thus far, you can see that KSR’s supporters are primarily law professors and large companies likely to get sued for patent infringement.  They are hoping to lower the obviousness standard — making it easier to invalidate a patent during litigation.  It is not clear, however, that the Sakraida standard is actually a higher patentability bar — that all depends on the meaning of a “functional-shift.”  That said, many of the potential defendants will be happy if the law becomes more unsettled — the result at least gives them more reason to appeal and would thus increase the plaintiff’s litigation costs (marginally lowering the number of infringement suits filed).  Notably, none of the major bar associations support the petitioner.

What follows is a brief review of those documents. The original documents themselves are accessible through links at the bottom of the article.

Petitioner KSR’s Brief

KSR’s strongest case is that the way the courts determine obviousness today (the TSM test) is not based on any statutory language nor is it based on any Supreme Court jurisprudence. Rather, the CAFC has created the TSM test out of whole cloth and crafted it in a way that inappropriately rejects Supreme Court precedent.  The extremely well researched and written brief traces the history of obviousness jurisdiction and uses that history as the primary basis for its conclusions.

One interesting argument is KSR’s position that provides 103(a) a condition for patentability rather than a condition for challenging patentability.  This appears to be an argument directed primarily to patent prosecution — that the applicant should be the one making an up-front showing of non-obviousness to satisfy section 103(a) rather than the PTO being forced to open with its rejection.   

Finally, KSR makes clear that the TSM test sets the patentability bar too low and allows too many technically trivial inventions to receive patent protection.

The only thing lacking here is any strong guidance for what obviousness test should arise to replace the soon to be displaced TSM test. KSR argues for little more than “adherence to [the Court’s] precedents.”  The result will certainly be a number of years of turmoil — especially on the side of patent prosecution.

Bush Administration in Support of Petitioner

The Government argues that the CAFC has “inappropriately broadens the category of nonobvious and therefore patentable inventions” by limiting the obviousness determination to a single rigid test. Rather, the Government would return to the rules of Graham v. John Deere, that try to determine “whether the claimed invention manifests the extraordinary level of innovation, beyond the capabilities of a person having ordinary skill in the art, that warrants the award of a patent.”

In particular, the brief points out that the TSM test is not wrong.  Rather, the problem is that the TSM test should not be the only test available to determine whether an invention is obvious. For instance, the Government argues that PTO Examiners should be able to reject claims based on their “basic knowledge” or “common sense.”

Law and History Professors (Sarnoff) in Support of Petitioner

Professor Sarnoff along with six other professors add to the debate by recognizing that the Supreme Court’s precedent, although “sound,” needs to be clarified: The professors

suggest [as a clarification to Graham] that the Court hold that the obviousness inquiry is designed to prohibit patents on inventions that could have been made by those skilled in the art within a reasonable period of time (following the time that the invention at issue was actually made) and within reasonable budgetary constraints.

The professors also suggest several modifications (clarifications) of the burdens of proof of patentability.  Their first suggestion would be to remove the evidentiary burden on the PTO (or challenger in litigation) to satisfy the TSM test. Thus, even if the TSM test remains in effect, the initial burden would presumably be shifted to the patentee to prove that the test is not satisfied.

Another clarification would relate to the presumption of validity.

[T]he Court should clarify that a clear and convincing burden of proof should not apply to issues for which the relevant evidence was not previously considered by the Patent Office.

Progress and Freedom Foundation in Support of Petitioner

PFF is a think tank that supports free markets and usually strong property rights. (Richard Epstein and John Duffy are both members of PFF advisory counsel).  A strong property regime in the patent system means that issued patents should be valid and should clearly show their scope of coverage.  PFF’s contribution is to explore how improper hindsight can be avoided even without strict evidentiary requirements:

But adopting the correct standard does not require that USPTO or the courts give in to subjective whim, because there are administrative mechanisms that can be used to make the exercise of subjective judgment fair and reasonably consistent over time.

For example, USPTO could adopt the current Federal Circuit test as a first cut, because it does indeed represent a crucial benchmark. Any invention which fails the “teaching-suggestion-motivation” test is clearly not patentable. But this need not end the inquiry. If the examiner thinks he/she has a special case in which this test does not capture the reality of the situation, perhaps the matter could be referred to a multiperson review committee, thus eliminating the influence of a single examiner’s whim. Or perhaps boards of outside experts could be established, or community peer review processes conducted over the Internet.

KSR v. Teleflex (Supreme Court 2006).

By Dennis Crouch

The first round of briefs have now been filed in the much anticipated KSR case that will address fundamental questions of patentability. [Copies of briefs are found below] The doctrine of nonobviousness ensures that patent rights are not granted on inventions that are simply throw-away modifications of prior technology.  Questions of obviousness are at play in virtually every patent case, in both proceedings before the USPTO and during infringement litigation.

Obviousness has always been a “squishy” term, but over the past twenty-five years, the Court of Appeals for the Federal Circuit has developed a somewhat objective nonobviousness doctrine using a teaching/suggestion/motivation (TSM) test. According to the test, when various pieces of prior art each contain elements of an invention, the prior art can be combined together to invalidate a patent on the invention only when there is some motivation, suggestion, or teaching to combine the prior art.

KSR has asked the Supreme Court to rethink that approach and take a fresh look at the obviousness standard for patentability. The petition questions whether obviousness should require any proof of some suggestion or motivation to combine prior art references.

Question Presented: Whether the Federal Circuit erred in holding that a claimed invention cannot be held "obvious," and thus unpatentable under 35 U.S.C. sec. 103(a), in the absence of some proven "'teaching, suggestion or motivation' that would have led a person of ordinary skill in the art to combine the relevant prior art teachings in the manner claimed"?

Interestingly, the Supreme Court has not heard an obviousness since well before the founding of the Federal Circuit. In that case (Sakraida 1976), the Court held that a combination which only unites old elements with no change in their respective functions is precluded from patentability under 103(a).  Under the Sakraida standard, the Teleflex patent is arguably obvious.  In an article several years ago, Professor John Duffy identified this obviousness issue as one that should attract the Supreme Court’s attention.

[The Federal Circuit’s suggestion] test, which tends to make even seemingly trivial developments patentable, is entirely the Federal Circuit’s product.  It has no basis in the Supreme Court’s case law and may, in fact, be inconsistent with the Court’s most recent pronouncement on the subject (though that precedent is now more than a quarter century old).

Duffy, The Festo Decision and the Return of the Supreme Court to the Bar of Patents, 2002 S.Ct. Rev. 273, 340-41 (2003).  Now, Duffy, a former clerk of Justice Scalia, is part of the KSR team that is trying to change the rule of law.

The case itself concerns a patent covering a gas pedal for an automobile. KSR makes pedals for GM & Chevy trucks and was sued for infringement of the Teleflex patent.

Crouch’s notes: In my view, the question is not correctly presented because it focuses on the aspect of “proof.” Of course any decision on obviousness should be based on some sort of proof. I expect that the Court will, as they often do, ignore this particular question and instead answer the broader question of how “a court should go about deciding whether matter claimed in a patent should be deemed ‘non-obvious' subject matter.”  In fact, in its merits brief, KSR implicitly recognizes this more fundamental question in its summary of the case.

It is very likely that the Federal Circuit’s home-grown TSM test will be eliminated.  This leaves us with a gaping hole — the most likely successor is a return to Sakraida that would require a showing of some functional-shift caused by a combination of old elements.
