VirnetX (VHC) Says USPTO Rejects Reexamination Request by Cisco (CSCO)

December 20, 2011 9:03 AM EST
VirnetX Holding Corporation (AMEX: VHC), 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.
