Guest guest Posted January 6, 2004 Report Share Posted January 6, 2004 This is not good news for Purdue Pharma, but good news for us since a generic form of Oxycontin ahould be available pretty soon. Jerry/NC ********************************** Purdue spanked by judge for Oxycontin patent claim NEW YORK (AP) - A federal judge ruled that Purdue Pharma patents protecting its painkiller Oxycontin are invalid, clearing the way for drug maker Endo Pharmaceuticals Holdings to sell a generic version of the drug. The news sent Endo shares surging $2.86, or 15%, to $21.98 in afternoon trading Monday on the Nasdaq Stock Market. Purdue, based in Stamford, Conn., sued Endo for patent infringement in 2000 after Endo filed an abbreviated new drug application with the Food and Drug Administration to sell generic Oxycontin, which is designed to treat moderate to severe pain. In a 50-page opinion issued Monday, U.S. District Judge Sidney H. Stein in Manhattan found that while Endo violated three of closely held Purdue's patents on the drug, Endo " has proven by clear and convincing evidence that the patents are invalid due to Purdue's inequitable conduct before the Patent and Trademark Office during the prosecution of the patents in suit. " Representatives from Purdue and Endo weren't immediately available to comment on the suit. Endo attorney Filardi said the ruling would allow Endo to put its own version of Oxycontin on the shelves. " Endo has proven by required evidence that the patents are unenforceable, " he said. " In other words, the court has found that Purdue deceived the patent office. " Endo, based in Chadds Ford, Pa., also makes other pain killers including Percocet and Percodan tablets. Quote Link to comment Share on other sites More sharing options...
