Argentum Pharmaceuticals and KVK Tech Succeed in Starting Patent Cancellation Trial Against Alcon’s PAZEO®

NEW YORK, Aug. 1, 2016 /PRNewswire/ — The U.S. Patent & Trademark Office (PTO) granted a petition for inter partes review (IPR) filed by Argentum Pharmaceuticals LLC and its manufacturing partner KVK Tech, against all challenged claims of the sole patent listed as covering Alcon’s PAZEO® (0.7% olopatadine hydrochloride ophthalmic solution) drug in the Food & Drug Administration’s Orange Book.  Argentum and KVK challenged claims 1-4, 8, 12, 13, 21 and 22 of Alcon’s U.S. Patent No. 8,791,154, and on July 18, 2016 the PTO concluded there is a “reasonable likelihood that [petitioner] would prevail in showing that the claims it challenges are unpatentable”.  The decision marks the beginning of an IPR trial that will be conducted by three specialist patent judges within the PTO’s Patent Trial & Appeal Board (PTAB).  A final decision on patentability in the IPR is due within 1 year.  The successful institution of this petition marks the first time the PTAB has instituted an IPR against this patent.
