Amgen v. Sanofi: Discussing the SCOTUS Decision


In its May 18 ruling, the U.S. Supreme Court sided with Sanofi in Amgen v. Sanofi, 598 U.S. ____ (2023), a dispute concerning broad functional genus claims for antibodies. The Supreme Court held that under 35 U.S.C. § 112(a), "Amgen has failed to enable all that it has claimed, even allowing for a reasonable degree of experimentation." 598 U.S. ____, at *15. The Court noted that the claims at issue covered "the entire genus" of antibodies that (1) "bind to specific amino acid residues on PCSK9," and (2) "block PCSK9 from binding to [LDL receptors]." Id. at *5. The unanimous opinion states, "If a patent claims an entire class of processes, machines, manufactures, or compositions of matter, the patent's specification must enable a person skilled in the art to make and use the entire class." Id. at *13.
