Argentum Succeeds In Starting Patent Cancellation Trial Against Mylan's DYMISTA

Published: Oct 02, 2017

NEW YORK, Sept. 29, 2017 /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 last-expiring patent listed as covering Mylan Specialty LP's DYMISTA® (azelastine hydrochloride/fluticasone propionate nasal spray) drug in the Food & Drug Administration's Orange Book.  Argentum and KVK challenged claims 1, 4-6, 24-26, 29, and 42-44 of U.S. Patent No. 8,168,620, and on August 21, 2017 the PTO concluded there is a "reasonable likelihood that [Argentum] would prevail in showing that claims 1, 4-6, 24-26, 29, and 42-44 of the '620 patent 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.  This institution decision marks the first time the PTAB has instituted an IPR against any Orange Book listed patent covering DYMISTA®.
