Colibri Heart Valve v. Medtronic Corevalve (Fed. Cir., July 18, 2025) 2023-2153

This Federal Circuit opinion addresses an appeal regarding a patent infringement lawsuit between Colibri Heart Valve LLC and Medtronic CoreValve, LLC. The core of the dispute revolves around U.S. Patent No. 8,900,294, owned by Colibri, which describes a method for implanting artificial heart valves with a "do-over" or recapture mechanism. Colibri accused Medtronic of inducing infringement of this patent through the use of Medtronic's "Evolut" heart valve products. The court ultimately reversed a lower court's decision, ruling that prosecution history estoppel prevented Colibri from asserting infringement under the doctrine of equivalents due to the cancellation of a related claim during the patent's prosecution.
