The Federal Circuit heard a steady stream of cases from the Patent Trial and Appeal Board (PTAB) in 2019 as appeals of PTAB final written decisions seem to have become de rigueur.  PTAB appeals are now the largest single component of the Federal Circuit docket with over 600 appeals docketed in FY2019 – almost double the number of appeals that the Federal Circuit received from District Court patent decisions.

Perhaps the most noteworthy Federal Circuit decision of 2019 came in Arthrex v. Smith & Nephew No. 2018-2140 (Fed. Cir. Oct. 31, 2019) where a Federal Circuit panel ruled that the way administrative patent judges (APJs) are appointed to the PTAB was unconstitutional and vacated the decision with a remand that the case be heard again by another PTAB panel.  The decision purportedly cures this problem going forward by severing a portion of the enabling legislation that prevents the administrative judges from being fired except for cause. The Arthrex decision appears to give everyone similarly situated the right to request a remand and rehearing before a different panel.  About 100 or less pending appeals appear to fall in this category.

On December 16, all of the parties to the Arthrex case sought en banc reconsideration of the case.  Smith & Nephew and the USPTO’s solicitor general argued that the appointments clause issue and, hence, unconstitutionality was wrongly decided by the Arthrex panel because APJ’s were not “superior officers” (requiring Senate confirmation).  Arthrex and the government argued that the Director of the USPTO has sufficient control over the PTAB judges, pointing out that the Director can assign APJs to particular matters, remove them from cases, and over-rule institution decisions by issuing sua sponte dismissals.  Arthrex’s en banc rehearing petition, on the other hand, argued that the decision didn’t go far enough and the proper remedy should have been to throw out all decisions rendered in AIA trials so far.  A decision on the en banc rehearing request is unlikely to made until February 2020. If the rehearing petition is granted, an actual en banc decision may not come until 2021.

Another noteworthy Federal Circuit decision came in June, 2019 in Regents of University of Minnesota v. LSI Corporation, No. 18-1559 (Fed. Cir. 2019), where the Federal Circuit made it clear that sovereign immunity does not apply to patent challenges brought pursuant to the 2011 America Invents Act (AIA), regardless of whether the immunity claim is raised by a Native American tribe or a state university trying to avoid patent adjudication.
