Cornerstone BioPharma, J-Med Pharmaceuticals and Sovereign Pharmaceuticals Settle Pending Litigation Concerning U.S. Patent No. 6,270,796 and AlleRx™ Dose Pack

Cary, NC -- (ReleaseWire) -- 01/25/2007 --Cornerstone BioPharma (“Cornerstone”) of Cary, North Carolina, and J-Med Pharmaceuticals (“J-Med”) of Boston, Massachusetts, today announced that they have settled pending patent litigation with Sovereign Pharmaceuticals, Ltd., (“Sovereign”) of Fort Worth, Texas, in connection with U.S. Patent No. 6,270,796 (“the ‘796 patent”). The litigation was brought by the patent owner J-Med and licensee Cornerstone, who markets and sells the AlleRx™ Dose Pack.

AlleRx™ Dose Pack is one of three respiratory focused brands in the Cornerstone product line. The AlleRx™ Dose Pack is a prescribed AM/PM dosing regimen, available in a 10-day and 30-day supply, indicated for relief of the symptoms of vasomotor rhinitis and allergic rhinitis (runny nose associated with high pollen counts and specific year-round allergens). Over 30 million people in the U.S. have been diagnosed with allergic rhinitis alone.

”Cornerstone is dedicated to the development and commercialization of niche respiratory products that serve both the healthcare professionals and their patients,” said Craig Collard, President and CEO of Cornerstone BioPharma. “We will continue to defend the licensed invention of the AlleRx™ Dose Pack against all infringers,” he added.

As part of the settlement, Sovereign entered into a consent judgment confirming the validity and enforceability of the ‘796 patent. Sovereign will cease manufacturing a product intended to be packaged in violation of the ‘796 patent. Sovereign has further agreed to a permanent injunction and admitted that the products they manufactured infringed the ‘796 patent. Cornerstone and J-Med have agreed to not pursue damages for Sovereign’s past infringement.

“The settlement and consent judgment entered by the Court confirm the validity and enforceability of J-Med’s ‘796 patent. With a substantial patent portfolio, J-Med remains dedicated to providing novel therapies to physicians and patients that significantly improve patient care,” said Allan Weinstein, M.D., President of J-Med Pharmaceuticals.

By agreement, Cornerstone, J-Med and Sovereign will make no further public announcements about the resolution of the litigation beyond these written statements.
