Patent case: St. Jude Medical LLC v. Snyders Heart Valve LLC, USA

St. Jude Medical failed to show that challenged claims of patent owned by Snyders had been anticipated by other patents, nor did it prove that a particular combination demonstrated obviousness.

Claims of a patent directed to an artificial heart valve manufactured by Snyders Heart Valve LLC and a system for inserting the valve were not proven unpatentable by St. Jude Medical in either of two inter partes review proceedings, the U.S. Court of Appeals for the Federal Circuit found. The Patent Trial and Appeal Board correctly found that St. Jude did not prove that the design and the materials used in the artificial heart valve were anticipated by other patents or that the device was unpatentable due to obviousness. However, the Board erred in finding that four of the challenged claims were unpatentable as anticipated by a prior art patent (St. Jude Medical, LLC v. Snyders Heart Valve LLC, October 15, 2020, Taranto, G.).
