Apple iPad 2 Included in Communications Patent Case

Apple has joined the likes of Cisco, NEC and Aastra in a lawsuit initiated by VirnetX over a patent that it argues, the three companies have infringed by releasing products that includes its secure data communication IP.

The patent, called “Agile Network Protocol for Secure Communications Using Secure Domain Names”, has apparently been used in "every version of the iPhone" that Apple has produced plus the iPod Touch and both iPad tablets.

Macobserver reports that VirtnetX defines itself as “Internet security software and technology company… engaged in commercializing its patent portfolio by developing a licensing program as well as developing software products designed to create a secure environment for real-time communication applications such as instant messaging, VoIP, smart phones, eReaders and video conferencing.”

It is not known whether VirnetX may decide to go after other big telecommunications companies like Nokia, Motorola or even Microsoft.

While we wouldn't call VirnetX a patent troll, it is worth noting that the patent infringement suit was filed last year in the Tyler Division of U.S. District Court in Eastern Texas, one which historically has not favoured the defending party in patent infringement suits.
