CAFC in Takeda: patent valid but no infringement

The result in Takeda v. Zydus


Zydus Pharmaceuticals USA, Inc. and Cadila Healthcare Limited (“appellants” or “Zydus”) appeal from a final judgment of the U.S. District Court for the District of New Jersey finding that appellants had infringed claim 1 of U.S. Patent No. 6,328,994 (“’994 patent”) and had failed to establish that it was invalid. For the reasons stated below, we reverse the district court’s finding of infringement, but affirm its ruling on invalidity.



Thus, patent valid but no infringement.
