Fenwick Secures Patent Win for VoxerNet

Mountain View, Calif. (July 3, 2014) – Fenwick & West announced today that it has secured a summary judgment of non-infringement for its client, Voxer, Inc., in a patent dispute with plaintiff IPVX Patent Holdings, Inc. 

Voxer is a start-up company located in San Francisco that provides an innovative push-to-talk voice messaging solution for Apple and Android devices. IPVX is a non-practicing patent assertion entity whose ’576 patent is directed to an improvement on a telephone answering machine that displays a list of missed calls and voicemails so that a user can selectively retrieve a desired voicemail message without having to listen to each recording sequentially. IPVX and its predecessor, Klausner Technologies, have asserted the ’576 patent against dozens of companies in the Eastern District of Texas. 

The case was originally filed in March 2012 in the Eastern District of Texas by IPVX’s predecessor, Klausner. Fenwick’s attorneys succeeded in transferring the case to the Northern District of California, where it was assigned to United States Magistrate Judge Howard R. Lloyd. On July 2, 2014, the parties appeared before Judge Lloyd and presented their arguments on claim construction and non-infringement. The Court granted Voxer’s motion for summary judgment the very next day, finding that Voxer’s push-to-talk voice messaging system cannot possibly infringe IPVX’s ’576 answering machine patent.

The Fenwick team included lead attorney David Hadden, Hector Ribera, Michael Saunders and Kunyu Ching.
