On April 5, 2021, the Patent Trial and Appeals Board (PTAB) remanded a July 2020 U.S. Court of Appeals for the Federal Circuit decision in the matter of Fitbit, Inc. v. Valencell, Inc., in which the Federal Circuit ruled that Fitbit could appeal the initial PTAB ruling for all instituted claims, even those brought forth by a joint petitioner prior to joining inter partes review (IPR) proceedings.
