In this case, the same patent, U.S. Patent No. 4,935,507 (the ’507 patent), occasions litigation in both the United States District Court for the Eastern District of Virginia and the United States District Court for the Northern District of Illinois. The Virginia District Court granted the motion of Lupin Ltd. and Lupin Pharmaceuticals Inc. (collectively Lupin) for summary judgment of noninfringement. In the other case, the Illinois District Court denied a preliminary injunction to Abbott Laboratories, the exclusive licensee of the ’507 patent, based on the claim construction from the Eastern District of Virginia.
Because the Eastern District of Virginia correctly construed the claims of the ’507 patent and correctly discerned no genuine issues of material fact on literal infringement of claims 2-5 or infringement by equivalents of claims 1-5, this court affirms its partial summary judgment of noninfringement. Likewise, this court affirms the Northern District of Illinois’ denial of Abbott’s motion for a preliminary injunction, based in large part on the same correct claim construction.
