Allergan Granted Temporary Restraining Order in ACULAR(R) Patent Infringement Case

IRVINE, Calif.--(HSMN NewsFeed)--Jan. 3, 2006--Allergan, Inc. (NYSE:AGN ) announced today that on December 29, 2005, in its patent infringement lawsuit against Apotex, Inc., Apotex Corp., and Novex Pharma (collectively the "Defendants"), the United District Court for the Northern District of California granted Allergan's and Syntex (USA) LLC's application for a temporary restraining order against the Defendants. In its ruling, the District Court ordered that the Defendants "are restrained and enjoined, pending the Court's decision as to whether a preliminary injunction should issue, from commercially manufacturing, using, offering to sell, or selling within the United States or importing into the United States" the generic version of ACULAR® (ketorolac tromethamine ophthalmic solution) 0.5% for which the Defendants have sought FDA approval via an abbreviated new drug application.

The patent infringement lawsuit was tried in June 2003, and on January 27, 2004, the District Court entered a judgment in Allergan's and Syntex's favor and against the Defendants, finding that Defendants' proposed generic ketorolac tromethamine ophthalmic solution infringed U.S. Patent No. 5,110,493 ("the '493 patent"). The matter was appealed by the Defendants to the Federal Circuit Court of Appeals, which upheld the District Court's finding of infringement but remanded the matter to the District Court for the District Court's reconsideration of the Defendants' claim that the '493 patent is "obvious" and thus invalid. In granting Allergan's and Syntex's application for a temporary restraining order, the District Court ruled that Allergan and Syntex "have a strong likelihood of success on the merits in defending against Defendants' claim that the U.S. Patent No. 5,110,493 is obvious" and noted that "the public interest strongly favors the enforcement of patent rights and encouraging innovation."

ACULAR® is indicated for the temporary relief of ocular itching due to seasonal allergic conjunctivitis and the treatment of post-operative inflammation in patients who have undergone cataract surgery.
