Appealed from: United States District Court for the District of New Jersey Judge William H. Walls

Bristol-Myers Squibb Company appeals from the decision of the United States District Court for the District of New Jersey granting the motion by Ben Venue Laboratories, Inc., Bedford Laboratories, Boehringer Ingelheim Corporation, Immunex Corporation, IVAX Corporation, Zenith Goldline Pharmaceuticals, Inc., Marsam Pharmaceuticals, Inc., Schein Pharmaceutical, Inc., and Mylan Pharmaceuticals, Inc. (collectively, “the defendants”) for summary judgment that claims 1-3 and 6 of U.S. Patent 5,641,803 and claims 1, 2, 5, 6, 8 and 9 of U.S. Patent 5,670,537 are invalid for anticipation. Bristol-Myers Squibb Co. v. Boehringer Ingelheim Corp., 86 F. Supp. 2d 433 (D.N.J. 2000) (“Bristol II”).

Because the district court did not err in holding claims 1-3 and 6 of the ’803 patent and claims 1, 2, 5 and 8 of the ’537 patent invalid, we affirm the court’s judgment as to those claims. The district court erred in holding claims 6 and 9 of the ’537 patent invalid, however. We therefore vacate the court’s grant of summary judgment with respect to those two claims.
