St. Jude Medical, LLC v. Snyders Heart Valve LLC, No. 19-2108 (Fed. Cir. 2020)Annotate this Case
The Snyders patent describes and claims an artificial heart valve and a system for inserting the valve. In 2017, St. Jude filed two petitions under 35 U.S.C. 311–19, seeking inter partes reviews (IPR) of claims 1, 2, 4–8, 10–13, 17–19, 21, 22, and 25–30. The Patent Trial and Appeal Board instituted two reviews, each addressing all the challenged claims. In IPR-105, the Board ruled that St. Jude failed to establish unpatentability of any of the challenged claims, rejecting the contention that all the challenged claims were anticipated by the Leonhardt patent and would have been obvious over Leonhardt plus either the Anderson patent or the Johnson and Imachi patents. In IPR-106, the Board found claims 1, 2, 6, and 8 anticipated by the Bessler patent, but it rejected St. Jude’s contentions as to all other claims, finding that St. Jude had not proved, as to all but claims 1, 2, 6, and 8, anticipation by Bessler or obviousness over Bessler combined with either Anderson or Johnson and Imachi.
The Federal Circuit affirmed the decision in IPR-105; reversed the finding in IPR-106 that Bessler anticipated claims 1, 2, 6, and 8; did not reach the anticipation argument as to claim 28; and affirmed the obviousness rejection in IPR-106.
