Despite Discovery Violations, Amneal Prevails on against Merck in Nasonex Patent Dispute

Merck appealed the lower court’s finding of non-infringement of U.S. Patent No. 6,127,353 (“the ‘353 patent”), which is directed toward mometasone furoate monohydrate (“MFM”), commercially used in Merck’s Nasonex… Merck further contended that the district court erred by basing its non-infringement ruling on the “Day 1 Batches” rather than the “A Batches” because the focus must be on what will be the final commercial product. However, the Federal Circuit rejected this argument by pointing out Merck’s failure to prove a material difference between the “Day 1 Batches” and the “Day 4 Batches” and “A Batches.”
