Supreme Court Hears Argument on Burden of Proof for DJ Plaintiff

The Supreme Court on November 5, 2013, heard oral argument on whether the burden of proof in an action for a declaratory judgment of non-infringement falls on the plaintiff licensee or on the defendant patentee. The debate centered around whether a patentee/defendant sued for a declaratory judgment of non-infringement is required to prove a case of infringement that was neither alleged nor arguably possible where the DJ plaintiff is a licensee. The Petitioner argued that the burden that would be on the patentee as infringement plaintiff does not change when it is a DJ defendant. The Respondent argued that, because the patentee cannot assert an infringement counterclaim against its licensee in good standing, the normal default rule places the burden on the party that initiates the action.

Clear & Convincing: Supreme Court Affirms CAFC in Microsoft v. i4i

icrosoft wanted to see that changed, with prior art not considered by the Patent Office requiring a lower evidentiary threshold to invalidate. To rule in Microsoft’s favor would have required the Supreme Court to throw away 30 years of well-settled Federal Circuit law, as well as overruling Supreme Court precedent in effect since at least 1934, but which traces back in some form from that date a further 100 years. That was a bridge too far for the Supreme Court, who ruled today 9-0 (with concurring opinions but no dissents) that in order to invalidate patent claims 35 U.S.C. 282 requires clear and convincing evidence regardless of whether the prior art was known by the Patent Office during prosecution of the patent application.
