On May 18, 2023, the Supreme Court of the United States issued a unanimous decision in the case of Amgen Inc. et al. v. Sanofi, et al., No. 21-757.After a nine-year saga, beginning when Amgen sued Sanofi for allegedly infringing two of its patents in 2014, the Supreme Court held that Amgen's asserted patents failed to satisfy the enablement requirement under 35 U.S.C. § 112(a), and are thus invalid.
