The en banc US Court of Appeals for the Federal Circuit declined to review its October 2019 panel decision holding the appointment of administrative patent judges (APJs) at the US Patent and Trademark Office (PTO) unconstitutional because APJs are appointed as if they are “inferior officers” but vested with authority that is reserved for Senate-confirmed “principal officers” under the Constitution’s Appointments Clause. Arthrex, Inc. v. Smith & Nephew, Inc., Case No. 18-2140 (Fed. Cir. Mar. 23, 2020) (per curiam) (Moore, J., joined by O’Malley, Reyna and Chen, JJ., concurring) (Dyk, J., joined by Newman, Wallach and Hughes, JJ., dissenting).
