Purdue Pharma L.P. Announces Signing of Consent Judgment Ending OxyContin® Tablets Patent Lawsuit with Teva Pharmaceuticals

Teva admits Purdue Pharma’s OxyContin patents are valid, enforceable and infringed

Stamford, CT – (October 16, 2006) – The patent litigation between Purdue Pharma L.P. of Stamford, Connecticut and Teva Pharmaceuticals USA, Inc. of North Wales, Pennsylvania concerning certain Purdue Pharma patents on OxyContin® (oxycodone HCl controlled-release) Tablets ended on Thursday, October 12 with the signing of a Consent Judgment in the United States District Court for the Southern District of New York. In the Consent Judgment, Teva admits that Purdue Pharma’s OxyContin patents are valid, enforceable and infringed by Teva’s extended-release oxycodone products.

On August 29, 2006 Purdue Pharma and Teva announced their agreement to terminate the litigation subject to certain contingencies, including review by the United States antitrust agencies and the United States District Court for the Southern District of New York. The agreement permits Teva to continue sales of its generic version of OxyContin at least through March 31, 2007.

"We worked for years to invent an important medicine and lawfully obtained the patents necessary to protect it from infringers. We are pleased that Teva has acknowledged our innovation as well as our rights to enforce our patents," said Michael Friedman, President and CEO of Purdue Pharma. "We will continue to enforce our patents vigorously against all infringers."

"We will continue to be innovators, constantly looking for new products to serve physicians and the patients in their care," Friedman concluded.

Purdue Pharma has filed infringement actions to protect its OxyContin patents against other companies. On February 1, 2006, the United State Circuit Court of Appeals for the Federal Circuit ruled the Purdue patents to have been infringed by extended-release oxycodone products sold by Endo Pharmaceuticals Inc. of Chadds Ford, Pennsylvania.

Purdue Pharma L.P. and its associated U.S. companies are privately-held pharmaceutical companies known for pioneering research on persistent pain. Headquartered in Stamford, CT, Purdue is engaged in the research, development, production, and distribution of both prescription and over-the-counter medicines and hospital products.
