Merck & Cie v. Gnosis, S.P.A., No. 14-1779 (Fed. Cir. 2015)
Annotate this CaseAt the request of Gnosis, the Patent Trial and Appeal Board instituted inter partes review of claims of Merck’s patent, which relates to methods of using folates to lower levels of homocysteine in the human body. Homocysteine is an amino acid that, when present in excessive quantities, can cause severe cardiovascular, ocular, neurological, and skeletal disorders. Merck filed a response and a motion to cancel claims 1–3, 5, 6, and 13, which the Board granted. The Board only reviewed the patentability of dependent claims 8, 9, 11, 12, 14, 15, and 19–22 and found them invalid for obviousness, 35 U.S.C. 103, in light of prior art. The Federal Circuit affirmed, finding that the Board’s factual findings to the contrary were supported by substantial evidence and rejecting Merck’s arguments that the prior art taught away from the claimed method and that objective indicia of non-obviousness further support the patentability of the claims.
