On April 11, 2022, Niazi Licensing Corporation (“Niazi”) succeeded in part in its appeal at the Federal Circuit in Niazi Licensing Corporation v. St. Jude Medical S.C. Inc. Niazi’s lawsuit alleged that St. Jude Medical S.C. Inc.’s (“St. Jude”) CPS telescoping catheter system infringed U.S. Patent No. 6,638,268, entitled “Catheter to Cannulate the Coronary Sinus” (the “‘268 patent”).
The district court determined that the terms “resilient” and “pliable” in the claims rendered all but one claim of the ‘268 patent indefinite and, therefore, invalid. However, the Federal Circuit reversed the district court’s holding and instead found that, although the terms may be broad, they are not uncertain. The Federal Circuit held that intrinsic record and extrinsic evidence are sufficient to inform a skilled artisan of the meanings of the terms with reasonable certainty. The court sent the case back to the district court to resolve any outstanding questions of whether St. Jude infringed the claims and whether St. Jude’s remaining invalidity defenses are applicable.
