Rethinking Fairness: The Scope of Assignor Estoppel Doctrine After Minerva
Assignor estoppel, a common-law doc- trine, may prevent the former employee, as the patent assignor, from asserting the patent invalidity defense. The doctrine prevents unfair practices where, after assigning all the patent rights, the assignor claims the invalidity of the assigned patent such that she may exploit the invention without infringement. This article discerns the breadth of assignor estoppel doctrine and its implications after a recent Supreme Court case Minerva Surgical, Inc. v. Hologic, Inc., 141 S. Ct. 2298 (2021).
