USPTO Says Wands Still Controls Post-Amgen in New Enablement Guidelines

The U.S. Patent and Trademark Office (USPTO) published guidelines for examiners today on the topic of enablement in light of the Supreme Court’s May 2023 decision in Amgen v. Sanofi. The Office’s view seems to largely mesh with what our guest authors concluded earlier today—Amgen isn’t getting rid of In re Wands and—at the USPTO at least—the decision has seemingly maintained the status quo.

Amgen is the Answer to Alice

The Supreme Court decided Amgen Inc. v. Sanofi on May 18, 2023, nearly nine years after its decision in Alice Corp. v. CLS Bank Int’l, 573 U.S. 208 (2014). Amgen was concerned with the enablement statute of the patent law, 35 U.S.C. § 112. In comparison, Alice was concerned with the eligibility statute of the patent law, 35 U.S.C. § 101, and has been highly criticized for creating a mess of patent eligibility. At first glance, these cases are distinguishable from one another, since they deal with different aspects of the patent laws. However, statutory interpretation and analysis should be the same in both instances.

Federal Circuit Axes Antibody Claims for Hemophilia Treatment Under Amgen

The U.S. Court of Appeals for the Federal Circuit (CAFC) today affirmed a district court’s grant of summary judgment that Baxalta, Inc. and Baxalta GmbH’s Hemophilia patent claims are invalid for a lack of enablement. The court said the facts of the case are “materially indistinguishable from those in Amgen.”… While Baxalta tried to argue its screening process does not require the type of trial and error described in Amgen and instead “predictably and reliably generates new claimed antibodies every time it is performed,” the court said “this does not take the process out of the realm of the trial-and-error approaches rejected in Amgen.”

Best Practices for Conquering the Enablement Requirement After Amgen

The Supreme Court’s decision in Amgen Inc. v. Sanofi, 143 S. Ct. 1243, 1248 (2023), found that antibody claims defined by their binding and blocking function lacked enablement…. The Supreme Court’s decision relied highly on the unpredictability of the art—scientists cannot always predict how substitutions of even single amino acids will affect the binding and/or blocking function of an antibody. The disclosed methods of identifying species within the scope of the claim were little more than “trial and error.”… The consensus seems to be that Amgen generally forecloses broad genus claims in the biotechnology field. The remaining questions are: Are patent applicants limited to claiming species (e., sequence listings)? What steps may a patent applicant take to obtain broader coverage?

District Court Decision Teaches Caution When Construing Claims to Encompass After-Arising Technology

Novartis is currently involved in a multi-district patent litigation campaign to block generic entrants for Entresto®, which is Novartis’ blockbuster heart medication. In the fall of 2022, Novartis went to trial on the validity of one of the asserted patents, U.S. Patent No. 8,101,659 (“the ‘659 patent”). On July 7, 2023, the district court invalidated the patent for lack of written description despite rejecting an enablement defense based upon the same evidence. The district court’s decision highlights a clear tension between claim construction and enablement that, if left to stand, could permit pharmaceutical companies to block lower-cost generic medications with patents they did not actually invent.
