Yeda Research & Dev. Co., Ltd. v. Abbott GMBH & Co. KG, No. 15-1662 (Fed. Cir. 2016)Annotate this Case
Abbott’s 915 patent discloses a protein, TBP-II, which binds to and neutralizes a protein called Tumor Necrosis Factor α (TNFα), which is associated with various immunological diseases. Following a 2008 remand by the district court, the Board of Patent Appeals rejected claims by Yeda that the patent was invalid as anticipated. In 2015, the district court affirmed. The issue of invalidity turned on whether the patent benefits from the filing dates from either of two German patent applications. If it did, then the field of prior art narrows to exclude the claimed anticipating reference. Whether the 915 patent was entitled to benefit from the German application’s filing date depends on whether the German application provided adequate written description support for the invention claimed in the 915 patent. The Federal Circuit affirmed the district court’s 2015 decision that Abbott’s 915 patent is supported by the written description of one of the German applications, rendering moot Yeda’s appeal concerning the 2008 decision.
