The US Court of Appeals for the Federal Circuit denied a petition for panel rehearing regarding the constitutionality of decisions issued by the United States Patent and Trademark Office (USPTO) Patent Trial and Appeal Board (PTAB), holding that its decision in Arthrex, Inc. v. Smith & Nephew, Inc. (IP Update, Vol. 22, No. 11) also applies to final decisions issued by administrative patent judges (APJs) in inter partes re-examinations. Virnetx v. Cisco Systems, Inc., Case No. 19-1671 (Fed. Cir. May 13, 2020) (O’Malley, J.). The Court also denied (per curiam) a concurrently filed petition for rehearing en banc.
