USPTO Declines to Reexamine Claims of VirnetX's U.S. Patent No. 7,188,180

VirnetX® Holding Corporation (NYSE: VHC), an Internet security software and technology company, today announced that, on December 17, 2011, the United States Patent and Trademark Office issued an order denying the request for inter partes reexamination of its U.S. Patent No. 7,188,180 filed by Cisco Systems, Inc. (NASDAQ: CSCO) on October 25, 2011.

In particular, the USPTO rejected each of Cisco's ten proposed validity challenges to the '180 patent, finding that Cisco had not shown that there is a reasonable likelihood that it will prevail with respect to any of the claims of the '180 patent. Thus, the USPTO declined to initiate reexamination and rejected Cisco's request at the outset.
