Paul Hastings Obtains Preliminary Injunction in a Patent Infringement Case on Behalf of Eisai Pharmaceuticals
Friday, March 28, 2008
New York, NY (March 28, 2008) – LawFuel – Patent Law News – Paul, Hastings, Janofsky & Walker LLP (Paul Hastings), a leading international law firm, announced today that the firm obtained a preliminary injunction on behalf of Eisai Co., Ltd. regarding the pharmaceutical company’s billion dollar a year Alzheimer’s disease drug, Aricept®.
The patent suit was filed following a submission to the US Food & Drug Administration by Teva Pharmaceuticals of an Abbreviated New Drug Application (ANDA) for a generic version of Aricept®, the active ingredient of which is donepezil hydrochloride. The generic drug maker charged that Eisai’s patent should be held unenforceable because Eisai had allegedly failed to disclose a copending patent application covering a different drug molecule invented by Eisai and a prior published article with intent to deceive the Patent Office.
The United States District Court for the District of New Jersey granted Eisai’s motion for a preliminary injunction, finding that Eisai’s patent was valid and infringed and that Teva’s remaining defense of patent unenforceability lacked substantial merit.
New York partners Bruce Wexler, Joseph O’Malley and Victoria Cundiff led the Paul Hastings team.
