Back to the future – Federal Circuit rejects narrow approach to relation back doctrine

Description

Abstract: The U.S. Court of Appeals for the Federal Circuit, the appellate court that hears all patent-related appeals, recently revived an infringement lawsuit based on the relation back doctrine. This article examines why the court found the trial court’s application of the doctrine, which resulted in the case being dismissed because of the statute of limitations, “overly restrictive.” Anza Technology, Inc. v. Mushkin, Inc., No. 19-1045, Aug. 16, 2019, Fed. Cir.
