In Senju Pharmaceutical Co. Ltd., et al. v. Apotex Inc., et al., Civil Action No. 07-779-SLR, the U.S. District Court for the District of Delaware, by and through a memorandum opinion entered by The Honorable Sue L. Robinson on June 14, 2010, entered judgment in favor of defendants, Apotex Inc. and Apotex Corp. (“Apotex”), and against plaintiffs, Senju Pharmaceutical Co. Ltd (“Senju”), Kyorin Pharmaceutical Co. Ltd. (“Kyorin”) and Allergan, Inc. (“Allergan”). The case is an infringement action that was tried by bench trial on January 12-14, 2010. In rendering judgment in favor of defendants, the Court concluded among other things that, although plaintiffs had demonstrated by a preponderance of the evidence that defendants’ ANDA product infringed claims 1-3, 6,7, and 9 of the patent in dispute, U.S. Patent No. 6,333,045 (“the ‘045 patent”), defendants demonstrated by clear and convincing evidence that those claims are invalid based on obviousness given the asserted prior art. Id. at 15-21 and 37.

A complete copy of the Court’s Memorandum Opinion is attached.
