Global-Tech v. SEB: Respondent and Additional Amicus Briefs

By Jason Rantanen

In Global-Tech v. SEB, the Supreme Court is addressing the state of mind requirement for inducement of infringement.  The petitioner, along with several amicus briefs filed in support, argues that inducement should require that the accused intend to infringe the patent, and that the accused infringer must know of the patent being infringed.  Earlier Patently-O discussions of those briefs are available here and here.

Last week, the respondent (SEB) filed its briefs.  SEB argues that there is no basis for requiring evidence that the accused party possess actual knowledge of the patent; rather, inducement must require a lower state of mind standard than both 35 U.S.C. § 271(c) (contributory infringement) and willful infringement, a standard that is met by Pentalpha's conduct.  In the alternative, SEB argues that Pentalpha's conduct constituted willful blindness, which SEB contends is a form of constructive knowledge and thus is sufficient for inducement.  In addition, SEB argues that the Court should affirm because all the damages were attributable to Pentalpha's direct infringement and because, through it's finding of willful infringement, the jury necessarily found that Pentalpha had actual knowledge of the patent.

Several amicus curiae have also filed briefs in support of the respondent, all arguing that inducement should require only intent to cause the acts as opposed to some form of scienter with respect to whether those acts infringe a patent.  Among these is the brief of a group of law professors led by Professor Ted Sichelman, argues that inducement should require only specific intent to cause the infringing acts – not some form of scienter with respect to whether the acts infringed a patent.  The brief supports this argument by looking to tort and criminal law, pointing out that in those contexts it is not necessary for the accused to know that that the acts violate a legal duty – only that the accused intend to cause the acts themselves. It also argues that prior to the 1952 Patent Act, no court (with one exception as dicta), held that indirect infringement required knowledge of the patent.  Thus, the brief argues, while inducement of infringement should require specific intent to further the acts of direct infringement, it did not traditionally – and should not – require any form of knowledge of whether those acts infringe a patent. 

Oral Argument is set for Wednesday, February 23, 2011.

Global-Tech v. SEB: Amicus Briefs

By Jason Rantanen

Several amicus briefs supporting Global-Tech/neither party were filed yesterday.  Among them is a brief by 41 Law, Economics, and Business Professors in support of the Petitioner that parallels a similar brief filed in support of the petition for certiorari.  The merits brief, coordinated by Mark Lemley, Timothy Holbrook, and Lynda Oswald, argues that the Court should reject the "deliberate indifference" standard articulated by the Federal Circuit in SEB, and instead hold that inducement require that the defendant "be aware of a patent and encourage an act that it knows or should know would infringe that patent."  In anticipation of an argument that may be made in support of the Respondent, the brief also asserts that a strict liability standard for inducement would be disastrous.  The brief can be directly downloaded here: Download 10-6, tsac, 41 Law, Economics, and Business Professors

Untouchable: Sham Reexamination Requests

Lockwood v. SHEPPARD MULLIN (Fed. Cir. 2010) (nonprecedential)

Last week, I wrote about the Lockwood case involving allegations that Sheppard Mullin should be held liable for filing a sham reexamination request.  The district court had dismissed Lockwood's complaint — holding that there could be no federal cause of action for filing a sham reexamination request because, inter alia, that area is preempted by Federal Patent Laws. 

The Federal Circuit (Judges Newman, Plager, and Prost) has now decided the appeal — affirming the district court decision without opinion. (Rule 36).  Federal Circuit Rule 36 indicate that a panel may “enter a judgment of affirmance without opinion . . . [if] an opinion would have no precedential value.”  Here, the Rule 36 opinion is surprising given the lack of precedent on this topic, the obvious third-party interest in the outcome of the case, and the dramatic rise in the use of reexaminations over the past decade.

In the appeal, briefs amici were filed by the TPL Group (arguing that “nothing in the reexamination law … indicates that Congress intended to prevent patent holders from [pursuing a state law claim of unlawful business conduct] when a baseless request for reexamination is filed for the purpose of harming a competitor); Professor Hricik (arguing that liability should be available); NDP Managed Security (arguing that the suit is not barred by California law); and O'Melveny & Myers (arguing that the reexamination statute preempts a court action for sham filing of a reexamination).  Raymond Mercado (who previously worked for Lockwood) has written an academic article explaining his findings of extensive “reexamination abuse” by third-party requesters.  Mercado argues that patentee's subject to sham reexamination requests should certainly be able to bring an action under the common law tort of malicious prosecution. In addition, Mercado argues for a new federal cause of action.

This case opens the door to some amount of bad-behaviour in the filing of reexamination requests.  Patent attorneys who file sham-requests  can be sanctioned through the USPTO's Office of Enrollment & Discipline. However, an anonymous third party requester may be untouchable.

Guest Post: What Ultimately Matters In Deciding the “Gene Patenting” Issue?

By Jacqueline Wright Bonilla, PhD, JD. Ms. Bonilla is a partner at Foley & Lardner and filed an amicus brief supporting Myriad's position.

In entering the fray of this discussion, I note that I, along with two of my colleagues at Foley & Lardner LLP, submitted an amicus brief in the AMP v. PTO (a/k/a ACLU v. Myriad) "gene patenting" case on behalf of our clients Rosetta Genomics and George Mason University. In addition to our brief, other colleagues at our firm submitted a different amicus brief on behalf of a different client, Alnylam Pharmaceuticals. Both briefs, along with Myriad's brief and a number of other amicus briefs filed last week, support a reversal of the district court opinion as it pertains to "isolated DNA" composition claims. These briefs agree that such claims are patent eligible under current law, and should continue to meet the threshold of 35 U.S.C. § 101 as a matter of policy and social considerations. We are sensitive to dire consequence to biotech innovation in the face of a possible alternative outcome.

As it turns out, however, while such briefs agree on patent eligibility of "isolated DNA" claims, a number of briefs differ in viewpoints regarding applicable law, and even which cases are relevant versus not. As such, a reading of just the briefs filed with the Federal Circuit so far—even without considering the ACLU brief yet to be filed, much less amicus briefs filed in support of the ACLU's position—underscores a point worth mentioning.

The point is this: reasonable minds can differ on an interpretation of what constitutes relevant case law and how it should be interpreted in this case. This point is often missed in the hubbub we see in the press. For instance, many have commented on the amicus brief filed by the Department of Justice last week. Some have accused the DOJ of misreading the law entirely and attempting to eviscerate biotechnology innovation altogether. Such viewpoints misread the point of the DOJ brief, in my opinion.

Look what the DOJ brief actually says. It argues that the district court got it wrong in certain important respects. As stated in the DOJ brief:

… the district court erroneously cast doubt on the patent-eligibility of a broad range of manmade compositions of matter whose value derives from the information encoding capacity of DNA. Such compositions—e.g., cDNAs, vectors, recombinant plasmids, and chimeric proteins, as well as countless industrial products, such as vaccines and genetically modified crops, created with the aid of such molecules—are in every meaningful sense the fruits of human ingenuity and thus qualify as "'human-made inventions'" eligible for patent protection under section 101. [] The district court therefore erred in invalidating the challenged composition claims, such as claim 2 of the '282 patent, that are directed solely to cDNAs.

DOJ brief, pages 9-10 (citations omitted). As part of this discussion, the DOJ likewise agrees with our position that claims directed to recombinant vectors comprising any isolated DNA—even DNA having a sequence exactly as it exists in nature—constitutes patentable subject matter. See DOJ brief, page 16, discussing claim 8 of the '282 patent. Thus, unlike the district court opinion, the DOJ proposal does not throw the entire biotech baby out with the bath water.

That said, it appears that the DOJ may cut off a hand of the biotech baby. It argues that "isolated DNA" comprising a sequence from genomic DNA as it exists in a body does not constitute patentable subject matter. The DOJ brief (pages 10-11) argues that the "chemical structure of native human genes is a product of nature," even "when that structure is 'isolated' from its natural environment."

This position presents a slippery slope of considerable concern to those affiliated with biotech innovators responsible for actually getting medical products to patients. For example, the DOJ sidesteps an important scientific fact: all isolated nucleotide compositions—regardless of sequence—are, in fact, engineered DNA molecules. Such DNA molecules are necessarily, by definition of their existence in an isolated form, "human made" inventions. These products simply do not exist without human intervention. Thus, how does one successfully distinguish what is really "human made"? Moreover, human involvement is needed to identify valuable isolated nucleic acid molecules, such as DNA vaccines, PCR probes, interfering or micro RNA, etc., and then isolate them. When exactly is the human involvement sufficient to meet § 101? An additional slippery slope in the DOJ position is that many non-nucleotide compositions also exist as "products of nature" in a human body or other natural physical state. These compositions include many valuable small molecule pharmaceuticals, proteins, antibodies, just to name a few. Such compositions could likewise be subject to the same legal reasoning propagated in the DOJ brief. In other words, the fallout of the DOJ's position has wide-sweeping implications, even if not as flabbergastingly debilitating as the district court opinion.

This all said, I propose that it does no good to simply assert that the DOJ (or any party or judge for that matter) incorrectly reads relevant case law and/or misunderstands the science wholesale. As mentioned already, reasonable minds can differ on case law interpretation in this case, and how to apply scientific facts to the law. The sheer number of briefs and differences in positions—see DOJ versus USPTO as just one example—indicates this phenomenon in vivid color.

Thus, at the end of the day, the Federal Circuit and/or Supreme Court may ultimately decide the outcome of this case based on policy and social/economic considerations. The courts will consider case law, of course, but in reality may only apply it after the fact. I also believe that any precedential decision issued here, either way, will necessarily have at least some negative fallout. In fact, the patent system itself intends negative fallout to some people by virtue of granting a right to exclude others for a limited time. Thus, keeping the ideals of patent law in mind, it will be critical for courts to choose a course of action that provides the most amount of good, while causing the least amount of collateral damage. In other words, forget all the clever legal mumbo-jumbo—what do we want to happen here for the better collective good?

My understanding of the patent system is that it exists for the very purpose of stimulating innovation, as well as public disclosure of that innovation. As discussed at length in our amicus brief (and by others), abolishing patent eligibility of genetic inventions—not to mention inventions in other areas of health and medicine potentially impacted by a decision here—will have more of a dampening effect on research, development and innovation than any patent right could ever have.

My hope is that courts will remain ever conscious of slippery slopes created by any one interpretation of the law and application of science. No one wins if we inappropriately dampen incentives for innovators to discover, apply and provide innovation to the benefit of humans.

US Government Argues in Court that Isolated Genes are Unpatentable

AMP v. Myriad (Fed. Cir. 2010)

In March, 2010, District Court Judge Robert Sweet held Myriad's gene patent claims invalid for failing to satisfy the subject matter eligibility requirements of 35 U.S.C. 101.  The ruling was directed toward claims that cover particular isolated DNA molecules (genes) and processes of detecting and screening for those genes, but was written broadly enough to essentially invalidate all patents covering genes that were isolated from an organism. 

Last month, I heard a rumor that Obama administration science and legal advisors outside of the USPTO supported Judge Sweet's ruling.  At the time I disregarded that suggestion as unlikely. I was wrong. [Andy Pollack at the NYTimes has the scoop]

The US Department of Justice (DOJ) has now filed an amicus brief supporting the lower court decision — arguing that isolated genes are unpatentable because they improperly claim a product of naturer [Link to Brief]:

The district court correctly held . . . that genomic DNA that has merely been isolated from the human body, without further alteration or manipulation, is not patent-eligible. Unlike the genetically engineered microorganism in Chakrabarty, the unique chain of chemical base pairs that induces a human cell to express a BRCA protein is not a “human-made invention.” Nor is the fact that particular natural mutations in that unique chain increase a woman’s chance of contracting breast or ovarian cancer. Indeed, the relationship between a naturally occurring nucleotide sequence and the molecule it expresses in a human cell — that is, the relationship between genotype and phenotype — is simply a law of nature. The chemical structure of native human genes is a product of nature, and it is no less a product of nature when that structure is “isolated” from its natural environment than are cotton fibers that have been separated from cotton seeds or coal that has been extracted from the earth.

. . . .

Thus, the patent laws embrace gene replacement therapies, engineered biologic drugs, methods of modifying the properties of plants or generating biofuels, and similar advanced applications of biotechnology. Crossing the threshold of section 101, however, requires something more than identifying and isolating what has always existed in nature, no matter how difficult or useful that discovery may be.

. . . .

A product of nature is unpatentable because it is not the inventive work of humankind. That essential rule cannot be circumvented by drafting claims for the same natural product removed from its natural environment and proclaiming the result “pure.”

Gene Patents on Appeal: ACLU’s Recusal Motion

Association for Molecular Pathology (AMP) and the American Civil Liberties Union (ACLU) v. United States Patent and Trademark Office (USPTO) and Myriad Genetics (Myriad) (Fed. Cir. 2010)

In a May 2010 decision, Judge Sweet of the Southern District of New York issued an opinion that would render most gene patents invalid for failing to claim patentable subject matter under 35 U.S.C. 101.  That high-profile case is now on an appeal, and has the potential of shifting US patent law both by its in-court and out-of-court impact.

Even before filing a substantive brief on the merits, the declaratory judgment plaintiffs (AMP & ACLU) filed a motion asking that Chief Judge Rader recuse himself from potentially hearing the decision. AMP argues that the Chief’s public statements regarding this case “have created an appearance of partiality that calls into question his ability to engage in impartial legal analysis.”

Notably, while attending a BIO meeting, Judge Rader reportedly responded to a comment by Professor Whealan (and former Rader clerk) that there are no real “legal standards for making [a Section 101] decision. . . [U]sing Section 101 to say that the subject matter is unpatentable is so blunt a tool that there is no neutral step to [draw] a line here [between what is and is not patentable].”  In Judge Rader’s construct, the lack of a clear legal standard means that the decision will then be based on “politics. It’s what you believe in your soul, but it isn’t the law.”  In another conference (this time at Fordham Law School), AMP’s attorney Dan Ravicher was speaking and Chief Judge Rader asked Ravicher a question “hinting at disagreement” with Ravicher’s position.  In particular, the Ravicher-Rader colloquy was quoted as follows:

Ravicher (pointing to a bottle of water): "Was that [purification] sufficient intervention between what God gave us … and what man created to merit a patent?"

Chief Judge Rader: "How many people have died of water pollution over the course of human events? Probably billions."

Two responses to the ACLU motion have been filed. 

First, Myriad responded that the cited statements by Chief Judge Rader “do not even suggest how Chief Judge Rader might vote, were he a member of the panel assigned to decide this case.”

The second filing is by the Federal Circuit Bar Association (FCBA) as amicus. The FCBA argues strongly that Judges should be encouraged to participate in educational conferences such as the BIO meeting and Fordham Law School.  The FCBA makes the important point that “Just as it is important that judges recuse themselves when the rules require it, it is equally important that judges refuse to recuse themselves where the rules do not require it.”  Granting recusal on the thin-evidence presented here would have the two primary effects of (1) discouraging sitting Federal Circuit judges from participating in public conversations and (2) encourage more strategic recusal motions.  The FCBA motion was a joint effort by former Deputy Solicitor General Thomas Hungar (Gibson Dunn) and the oft-paired team of Ed Reines & Amber Rovner (Weil Gotshal).

This particular motion may never be decided. Since the panel has not yet been assigned for this appeal, the CAFC has refrained from deciding the motion. In a letter to AMP, the court indicated that “[i]n the event that Judge Rader is assigned, the motion will be transmitted to him.”

Changing the Law of Inequitable Conduct: Abbot Briefs its Case

TheraSense, Inc. (Abbott Labs.) v. Becton, Dickinson and Co. (Fed. Cir. 2010)(En Banc Rehearing)

In TheraSense v. BD, an en banc Federal Circuit is reconsidering the doctrinal structure that it has created to handle allegations of inequitable conduct. Abbott (the patent holder) has filed its opening merits brief arguing that the current law of inequitable conduct over-extends its proper bounds.  In an eloquent opening statement, Abbott writes:

The question in this case is not whether to reform the doctrine of inequitable conduct, but whether to restore it—to its origins in Supreme Court precedent; to the confines Congress intended in the 1952 Patent Act; to the standards this Court articulated en banc in Kingsdown Medical Consultants v. Hollister, Inc., 863 F.2d 867 (Fed. Cir. 1988); and to the standards that govern in other areas of law. This Court has expanded the inequitable conduct doctrine well beyond those boundaries, and the result has been an “ongoing pandemic” of inequitable conduct charges. Taltech Ltd. v. Esquel Enters. Ltd., 604 F.3d 1324, 1335 (Fed. Cir. 2010) (Gajarsa, J., dissenting). The expansion has rendered valuable patents unenforceable based on minor omissions far afield from the doctrine’s purposes. And it has converted the federal courts into roving commissions to enforce standards of conduct before the PTO without regard to whether the alleged infractions had any impact. . . .

Supreme Court precedent and the legal principles embodied in the Patent Act reserve those extreme consequences for the most egregious circumstances—cases where a party “obtained its patent by fraud.” Walker Process Equip., Inc. v. Food Mach. & Chem. Corp., 382 U.S. 172, 175, 176 (1965). As this Court has recognized, the Supreme Court has held patents unenforceable “only in cases of ‘fraud on the Patent Office.’” Star Scientific, 537 F.3d at 1365-66 (quoting Hazel–Atlas Glass Co. v. Hartford-Empire Co., 322 U.S. 238, 250-51 (1944)); see Larson Mfg. Co. of S.D., Inc. v. Aluminart Prods. Ltd., 559 F.3d 1317, 1343 (Fed. Cir. 2009) (Linn, J., concurring). A party seeking to invalidate a trademark or copyright based on misconduct before the agency must prove it was the product of fraud. The standard should be no less stringent here.

Briefs Filed Thus Far:

PSA For TheraSense Amici: Filing Permission Must Be Requested

The TheraSense en banc order states that “amicus briefs may be filed without leave of court but otherwise must comply with Federal Rule of Appellate Procedure 29 and Federal Circuit Rule 29.”  Although I would have guessed that this statement relieved amicus filers from the requirement of seeking permission of the parties or filing a motion, the Federal Circuit clerk is apparently requiring that amici either (1) obtain consent from all parties, or (2) if fewer than all parties consent, submit a motion to the court for permission to file the brief.  Several amicus briefs filed in the case have apparently been rejected for failure to comply with these requirements.

This information comes from Professor Christian Mammen (visiting at Hastings). Mammen is drafting a brief in TheraSense that argues three primary points: (1) that materiality should focus on patentability issues, and should defer to the PTO's Rule 56; (2) that there should be an increased focus on the clear and convincing standard of proof for intent (with corollaries that "should have known" and "gross negligence" should be abolished, and the Star Scientific "single most reasonable inference" test is a good starting point); and (3) if there is a sufficient increase in the required thresholds for both materiality and intent, the balancing step (which is often ignored in any event) may be abandoned.  Legal academics or others potentially interested joining his brief should contact him at mammenc@uchastings.edu.

Statutory Guidelines for Inequitable Conduct

In TheraSense, the en banc Federal Circuit is looking to rewrite the rules of inequitable conduct. By both its name and historic precedent, inequitable conduct appears to stem from non-statutory doctrines of equity. However, as with other equitable doctrines (such as injunctive relief), inequitable conduct could be somewhat tamed by the language of the Patent Act. In his TheraSense amicus brief, Professor Hricik is taking a useful approach by focusing on the statutory basis for holding claims unenforceable.

Two provisions of the Patent Act come to mind. One is general and the other specific. The general statute is 35 USC 282(1). That portion of Section 282 identifies "unenforceability" as a defense to patent infringement. In TheraSense, the court's first goal should be to interpret the meaning of unenforceability as found in that statute.

The more specific provision is Section 288. It is Section 288 that allows a patentee to assert infringement of remaining claims even after some of the claims are found invalid. Section 288 sets a specific limit on this separability principle. Namely, separability of claims does not apply when an invalidated claim was obtained through deceptive intent.

Whenever, without deceptive intention, a claim of a patent is invalid, an action may be maintained for the infringement of a claim of the patent which may be valid. 35 U.S.C. §288.

Section 288 is not exhaustive in its approach. Rather, the statute is only explicit that the remaining claims of a patent can be asserted even after one of the claims was found invalid, so long as that invalid claim was not obtained with deceptive intent. The statute does not explicitly indicate the result when an invalid claim was obtained with deceptive intent or, for that matter, when a valid claim was obtained with deceptive intent. In his brief, however, Professor Hricik concludes that these statutes should be read to – at times – limit the Court’s ability to automatically render all claims of a patent unenforceable after a finding of inequitable conduct.

Guest Post: Why Bilski Benefits Startup Companies


pic-98.jpg

I asked Professor Ted Sichelman to provide his thoughts on how the Bilski decision impacts start-up companies and their incentive to innovate. DC

By Ted Sichelman, University of San Diego School of Law

Before practicing law and becoming a professor, I founded and ran a small software company that sells speech recognition software to taxicab companies. After my company designed its technology, we filed for patents. Later on, when raising financing from angel and venture capital investors, they reviewed our pending applications carefully and considered them a way to stop potential competition. Indeed, in a recent survey of startup firms, the Berkeley Patent Survey—which I conducted with Robert Merges and Pamela Samuelson of UC Berkeley School of Law and Stuart Graham (now Chief Economist at the PTO)—startup executives reported that nearly 70% of venture capital firms and 50% of angel investors said that patents were important to their investment decisions. Relatively broad patentable subject matter assists startups in raising needed funds. As I have argued elsewhere, another reason for broad subject matter is that startups engage in substantial amounts of post-invention—but pre-commercialization—innovation that is not always technological in nature. For instance, many startups generate marketing, financial, legal, and other types of non-technological innovations during the costly commercialization process. Providing IP protection for these innovations not only can produce more of them, but also can help drive technology commercialization.

Assuming the Federal Circuit and the PTO do not go astray in implementing Bilski—which admittedly leaves many doors open to do so—the opinion will allow startups to continue to use patents to garner financing and will, hopefully, set an appropriate balance on the patentability of non-technological inventions. In particular, as I urged in an amicus brief with Professors Mark Lemley, Michael Risch, and Polk Wagner—Bilski rightly adheres to the 150-year old tradition that as long as the claimed invention is a machine, manufacture, composition of matter, or a process, only natural phenomena, laws of nature, and abstract ideas should be excluded from eligible subject matter.

One might contend that by allowing business methods—as well as software and other “intangible” innovations—to be patented, startup firms will encounter a greater “thicket” of patents, making it more difficult for them to enter particular markets. For example, an amicus brief in Bilski filed on behalf of “entrepreneurial and consumer advocates” argued that “if the PTO is permitted to grant broad business and service process patents, small start-up businesses would face an entirely new regime of business regulation – essentially requiring businesses to request private permits to operate from their competitors who have patents, independent of whatever technology the new business uses to compete.” Justice Stevens’ echoed this view by writing in his concurrence that business methods patents “can take a particular toll on small and upstart businesses.”

In actuality, under the Federal Circuit’s previous State Street Bank opinion, in operation for a decade prior to Bilski, the PTO regularly granted “broad business and service process patents” and there is little evidence that these patent-holders required startups to license them in any significant numbers. The Berkeley Patent Survey found that only 8% of the population of respondent software companies and 12% of venture-backed software companies had licensed-in even one patent. In sum total, a relatively low percentage, 0.6% and 3%, respectively, reported licensing a patent solely to avoid a lawsuit. And while Bilski ultimately holds that business methods are not per se unpatentable, the practical effect of the outcome will be to place unapplied business methods into the precluded “abstract idea” category. If implemented properly, such an approach will ensure that startups—and, indeed, larger and more established companies—are not unnecessarily subject to overly broad patents while maintaining robust incentives to innovate.

Obvious to Try? BIO Challenges Ex Parte Kubin

In re Kubin (Fed. Cir. 2008)

Immunex (a subsidiary of Amgen) is hoping to patent its a DNA sequence coding for a NK (Natural Killer) cell regulator protein. The BPAI rejected the “nucleic acid molecule” claim — finding it obvious over the prior art. [BPAI Decision]. This decision is one of only three precedential BPAI decisions in 2007.

Just looking at the claimed sequence, it would not seem obvious — its structure is not overly similar to other regulator proteins, and the unpredictable nature of protein folding makes it virtually impossible to predict whether a particular sequence would code for an appropriate protein.

Despite the structural uniqueness, the BPAI found the claim obvious because it could have been isolated and verified simply by following conventional laboratory techniques — thus, making it obvious to try.

Although the CAFC has previously warned the BPAI away from using “obvious to try” analysis in its 1995 In re Deuel case. There, the appellate court held that obviousness analysis of a structure should focus on the structure itself as compared to prior art structures.

In Kubin, the BPAI rejected Deuel as limited by the Supreme Court’s KSR decision. That case focused on combination claims, but included the stray quote that “the fact that a combination was obvious to try might show that it was obvious under Section 103.”

Here, the BPAI argued, the inventor wanted to isolate the NK Regulator and simply used known methods to do so. “Thus, isolating NAIL cDNA was ‘the product not of innovation but of ordinary skill and common sense.’” (again quoting KSR).

The case is now on appeal at the the CAFC. On June 10, the Biotechnology Industry Organization filed an amicus brief asking the court to cabin in the scope of KSR and hold that its obvious to try dicta does not abrogate the Deuel standard. Briefing is ongoing and a decision is not expected until the end of the year.

  • The PTO’s Obviousness Guidelines have the following rules for making an obviousness rejection based on the obvious to try reasoning:
    • (1) a finding that at the time of the invention, there had been a recognized problem or need in the art, which may include a design need or market pressure to solve a problem;
    • (2) a finding that there had been a finite number of identified, predictable potential solutions to the recognized need or problem;
    • (3) a finding that one of ordinary skill in the art could have pursued the known potential solutions with a reasonable expectation of success; and
    • (4) whatever additional findings based on the Graham factual inquiries may be necessary, in view of the facts of the case under consideration, to explain a conclusion of obviousness.The BPAI decision is notable for a few reasons, including the following two: (1) It was written by Nancy Linck, former PTO Solicitor, Newman law clerk, & PhD Chemist. Soon after authoring the decision, Linck left the firm to join the Rothwell Figg firm. (2) It is a unanimous opinion.
