Item 8.01 Other Events.

On March 28, 2012, we filed suit in the United States District Court for the District of Delaware against Par Pharmaceutical, Inc. and Par Pharmaceutical Companies, Inc. (collectively, “Par”). The lawsuit alleges that Par has infringed U.S. Patent No. 8,067,033 (the “’033 patent”) by filing an Abbreviated New Drug Application (“ANDA”) seeking approval from the U.S. Food and Drug Administration (“FDA”) to market a generic version of DUEXIS® tablets prior to the expiration of the patent. The ‘033 patent is listed in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known as the Orange Book. Our commencement of the patent infringement lawsuit stays, or bars, FDA approval of Par’s ANDA for 30 months or until an earlier district court decision that the ‘033 patent is not infringed or invalid.
