Aortic Innovations v. Edwards Lifesciences (Fed. Cir., October 27, 2025) 2024-1145

This episode relates to a United States Court of Appeals for the Federal Circuit opinion regarding a patent infringement case, Aortic Innovations LLC v. Edwards Lifesciences Corporation decided October 27, 2025. The core dispute involves the correct claim construction of the term "outer frame" in patents concerning transcatheter aortic valve replacement devices. The Plaintiff-Appellant, Aortic Innovations, appealed a stipulated judgment of non-infringement, which was based on the District Court of Delaware's construction of the claim term as a "self-expanding frame." The appellate court affirmed the district court's construction, agreeing that the patentee had acted as its own lexicographer by consistently using "outer frame" and "self-expanding frame" interchangeably throughout the specification, thereby limiting the claim scope. Consequently, the court affirmed the non-infringement judgment for three patents and dismissed the appeal for the fourth patent due to lack of jurisdiction because its asserted claims had been canceled.
