VirnetX Declares Essential Patents for 4G Security

VirnetX Holding Corporation (NYSE Amex: VHC), a secure real-time communications and collaboration technology company, today announced that it has declared to the 3GPP (3rd Generation Partnership Project) that its U.S. and international patents are or may be essential to Long Term Evolution (LTE) and 4G wireless specifications. The Company declared 23 patents and 28 applications that specifically pertain to 4G security standards.

VirnetX believes it will hold the majority of 4G essential patents related to Series 33 specifications that define security standards for LTE/4G and is prepared to license the use of its patents for incorporation into 4G related products such as chips, servers, smartphones, laptop computers, etc.

"Declaring our patents as essential to 4G is a significant complement to our already active licensing model," said Kendall Larsen, VirnetX CEO and President.

"This declaration opens the door today for hundreds of companies to license from us as they prepare for 4G. In addition, we believe that VirnetX not only holds the majority of security patents for 4G but also the most important."

"Aberdeen's benchmark research confirms the insatiable demand for mobile bandwidth, from both enterprise end-users and consumers, for the convenience of accessing data in every imaginable format," said Derek E. Brink, vice president and research fellow for IT security, Aberdeen Group. "As the massive transition from 3G to LTE/4G plays out over the next several years to meet this demand, essential 4G patent holders hope to realize a significant potential revenue stream from both upgrades and new equipment. VirnetX, by declaring its patents are or may be essential for security specifications as outlined by the 3GPP, sits in the trajectory of this transition and by doing so is positioning itself to do business with virtually every company transitioning to 4G."

The 3GPP is standardizing next generation wireless technology and brings together six standards organizations from North America, Europe and Asia to publish mobile standards including LTE/4G, GSM, GPRS and W-CDMA and is responsible for maintaining a registry of Intellectual Property Rights (IPR) declarations relevant to 3GPP standards that are submitted through organizational partners such as European Telecommunications Standards Institute (ETSI) and Alliance for Telecommunications Industry Standards (ATIS).
