CollaGenex acne-drug patent declined

CollaGenex Pharmaceuticals Inc. yesterday said the U.S. Patent and Trademark Office has issued a rejection of its patent application covering a method of treating acne, but the company will continue to press for approval. The Newtown-based company, which specializes in dermatological treatments, said the patent involved using chemically modified tetracylines, including incyclinide, in a new approach that would treat acne without fear of germ resistance. Colin W. Stewart, the company's president and chief executive officer, said CollaGenex will continue to pursue a patent and is "confident" that a "patent will ultimately issue to cover incyclinide."
