Endo Pharmaceuticals Announces Federal Circuit Court Of Appeals Remands OxyContin Patent Case

CHADDS FORD, Pa., Feb. 1 /PRNewswire-FirstCall/ -- Endo Pharmaceuticals Holdings Inc. today announced that the Federal Circuit Court of Appeals has vacated its unanimous June 7, 2005 affirmance of the Opinion and Order issued in Endo’s favor by the U.S. District Court for the Southern District of New York, which found Purdue liable for its inequitable conduct in the U.S. Patent and Trademark Office. The Federal Circuit also affirmed the district court’s finding that, if Purdue’s patents are enforceable, Endo’s oxycodone extended-release tablets infringe these patents. Further, the Federal Circuit issued a new opinion today remanding the case to the same district court for its further consideration as to whether the Purdue patents are unenforceable.

On June 7, 2005, Endo launched its oxycodone extended-release tablets, 10mg, 20mg, 40mg, and 80mg, a bioequivalent version of Purdue Frederick’s OxyContin(R), following the Federal Circuit’s affirmance of the district court’s opinion.

“Endo intends to vigorously pursue its position that Purdue’s patents are unenforceable as the federal district court originally ruled,” said Caroline B. Manogue, Endo’s executive vice president and chief legal officer.
