BPMC v. California Department of Health (Fed. Cir. 2007).
There is a reason why states generally support strong patent rights: States are increasingly major patent holders – based on inventions developed through federal grants. At the same time, states are generally immune from being sued for infringement. In this case, the CAFC allows the State of California to assert immunity based essentially on a case-numbering technicality.
The facts are simple: Kaiser filed a declaratory judgment action against the patent holder BPMC back in 1997. The California DOH intervened in that case — an action generally considered a waiver of immunity. That case was dismissed for improper venue. In 2006, BPMC filed an identical (mirror image) infringement action against the DOH asserting the identical patent and issues and in the same venue as the 1997 action. The issue here is whether the waiver in the original case of California’s 11th Amendment immunity applies also to the new case.
Here, the CAFC narrowly construed the state’s waiver of immunity to be strictly limited to 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. (Florida Prepaid).
Expect that this case will receive a petition for certiorari.
