The Federal Circuit’s recent decision in Samsung Electronics America, Inc. v. Prisua Engineering Corp., Appeals 2019-1169, -1260 (Fed. Cir. Feb. 4, 2020), is remarkable, but not for its holding: “the Board may not cancel claims for indefiniteness in an IPR proceeding.” After 10,000 IPRs, hardly anyone thought otherwise.
