Earlier this month, the Federal Circuit dismissed an appeal from the Patent Trial and Appeal Board (Board) where the Board upheld the patentability of a biologics patent. After Momenta Pharmaceuticals petitioned the Board for an inter partes review (IPR) of the patentability of Orencia® (abatacept), the Board sustained patentability and Momenta appealed. During the course of the appeal, Momenta ceased development of an abatacept biosimilar. The Federal Circuit held that the cessation of potential infringement mooted the injury and removed Momenta’s standing to maintain the appeal. Momenta Pharm., Inc. v. Bristol-Myers Squibb Co., No. 2017-1694, 2019 U.S. App. LEXIS 3786 (Fed. Cir. Feb. 7, 2019) (Before Newman, Dyk, and Chen, Circuit Judges) (Opinion for the Court, Newman, Circuit Judge).
