VirnetX Wins VPN Patent Dispute With Microsoft

VirnetX has won its patent dispute with software giant Microsoft.

The company announced on Tuesday that the two patents involved in its dispute with Microsoft have been confirmed as valid by the US Patent and Trademark Office.

The patents relate to communications security and virtual private network (VPN) technology in 4G mobile phone networks.

VirnetX alleged that Microsoft had infringed the patents with technology the company had included in its Windows and Office communications server products.

The two companies have settled the dispute out of court, with Microsoft paying $200 million to VirnetX.

VirnetX now plans to approach technology companies using the technology to sign licensing deals.

The confirmation by the Patent and Trademark Office came after Microsoft appealed the regulator to review the filings.

Speaking to the Wall Street Journal, VirnetX CEO Kendall Larsen said (opens in new tab): “This was the last question left to be answered before major players contemplated working with us.”

In a statement, Larsen said (opens in new tab): "The validation of these two key patents and all the claims associated with each by the USPTO further validates the importance and strength of our patent portfolio. Furthermore, this confirms that VirnetX has key patents related to one of the most ubiquitous and important security technologies, Virtual Private Networks."
