By December 22, 2011Press Releases

ZEPHYR COVE, Nevada. – December 20, 2011 – VirnetX® Holding Corporation (NYSE Amex: VHC), an Internet security software and technology company, today announced that, on December 17, 2011, the United States Patent and Trademark Office (“USPTO”) issued an order denying the request for inter partes reexamination of its U.S. Patent No. 7,188,180 (“’180 patent”) filed by Cisco Systems, Inc. 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.

“We are very pleased with the USPTO’s decision to reject Cisco’s arguments with respect to the ’180 patent,” said Kendall Larsen, VirnetX CEO and President. “This decision reinforces our belief in the strength of our intellectual property.”

The ’180 patent is one of many patents in VirnetX’s patent portfolio relating to establishing secure network communications.
