The U.S. Supreme Court on May 18, 2023 delivered its decision on the scope of the patent enablement requirement, set forth in 35 U.S.C. § 112, in the antibody dispute Amgen, Inc. v. Sanofi. While the parties obtained finality, many in the pharmaceutical and biotechnology industries received the opinion under a cloud of uncertainty and concern for exclusivity rights broad enough to both protect clinical candidates and deter competitors. While the patent bar may remain apprehensive, the Supreme Court kept the door open to genus claims.  The impact of the decision may not be as far-reaching as feared.
