Astra Aktiebolag, Aktiebolaget Hässle, Astra Merck Enterprises Inc., Astra Merck Inc., KBI-E Inc., KBI Inc., Astra Pharmaceuticals L.P., and AstraZeneca L.P. (collectively Astra) filed patent infringement suits against several pharmaceutical companies that were seeking permission from the Food and Drug Administration (FDA) to market generic versions of Prilosec®, Astra’s gastric acid inhibiting drug. The United States District Court for the Southern District of New York tried the case in four phases. Following a fifty-two day bench trial, the district court decided in Phases I and III that Andrx’s product infringes two of Astra’s patents, U.S. Patent Nos. 4,786,505 (the ’505 patent) and 4,853,230 (the ’230 patent). Astra Aktiebolag v. Andrx Pharm., Inc., 222 F. Supp. 2d 423 (S.D.N.Y. 2002). This court affirmed that judgment. In re Omeprazole Patent Litig., 84 Fed. App'x. 76, 2003 WL 22928641 (Fed. Cir. 2003) (Omeprazole II).
This appeal involves Phases II and IV of the same litigation. The district court entered a final judgment finding that Andrx Pharmaceuticals, Inc. (Andrx) literally infringed claims 1, 2, 3, 7, 9, 16, and 20-21 of Astra Aktiebolag’s United States Patent No. 6,013,281 (the ’281 patent). The trial court also entered several other judgments about the enforceability of that patent and other Astra patents. In re Omeprazole Patent Litig., M-21-81 (BSJ), MDL Docket No. 1291 (S.D.N.Y. July 15, 2004) (Final Judgment). At the same time, however, the district court also found the asserted claims of Astra’s ’281 patent anticipated or obvious. Final Judgment, slip op. at 2.
