MIAMI & NEW YORK, Sep 29, 2015 (BUSINESS WIRE) -- Noven Pharmaceuticals, Inc. announced today that the Patent Trial and Appeal Board (PTAB) of the U.S. Patent and Trademark Office issued its final decisions in the inter partes review proceedings (IPRs) Noven initiated against two Exelon®Patch (rivastigmine transdermal system) patents – U.S. Patent Nos. 6,316,023 (the " '023 patent") and 6,335,031 (the " '031 patent"). The PTAB found each of the claims of the '023 and '031 patents challenged by Noven in the IPRs to be unpatentable under 35 U.S.C. 103 as being obvious over the prior art. The PTAB decisions are subject to appeal to the U. S. Court of Appeals for the Federal Circuit.
Noven initiated the IPRs in connection with its Abbreviated New Drug Application for a generic version of Exelon®Patch which is currently pending with the U.S. Food and Drug Administration.
The favorable PTAB decisions follow a September 2015 U.S. District Court for the District of Delaware ruling that two of the same claims in the '031 patent addressed by the PTAB are not invalid. Noven is appealing that ruling.
Exelon®Patch is indicated for the treatment of mild to moderate dementia of the Alzheimer's type, and for the treatment of mild to moderate dementia associated with Parkinson's disease. Exelon®Patch is a registered trademark of Novartis AG.
