Federal Circuit finds genus didn’t anticipate species

Description

Abstract: Does the disclosure of a chemical genus render all of the species within it “inherently obvious” and therefore unpatentable? Not always, as the challenger in Mylan Pharmaceuticals Inc. v. Merck Sharp & Dohme Corp. learned. This article discusses the court’s finding that the class at issue didn’t meet the “at once envisage” standard for an invention to be inherently anticipated. Mylan Pharmaceuticals Inc. v. Merck Sharp & Dohme Corp., No. 21-2121 (Fed. Cir. Sept. 29, 2022).
