U.S. Supreme Court Limits Patent Law Doctrine of Assignor Estoppel

On June 29, 2021, the Supreme Court of the United States issued its ruling in Minerva Surgical, Inc. v. Hologic, Inc. limiting the patent law doctrine of assignor estoppel. The doctrine of assignor estoppel limits a party who has assigned a patent from later challenging the validity of that patent. The doctrine of assignor estoppel is grounded in the principle of fair dealing. When a party assigns its patent rights, the assignor makes an implicit representation to the assignee that the patent at issue is valid. However, in later raising an invalidity defense, the assignor disavows that warranty. In doing so, the assignor seeks to profit doubly—by gaining both the price of assigning the patent and the continued right to use the invention it covers.
