Another day, another lawsuit. VirnetX is suing Apple for — what else? — patent infringement.

The lawsuit — filed in the US District Court in the Eastern District of Texas — alleges that Apple violated its US patent (number 7188180) for “method for establishing secure communication link between computers for virtual private network,” reports “AppleInsider” (

The invention describes a technique “for establishing a secure communication link between a first computer and a second computer over a computer network.” This is accomplished by establishing a “secure communication mode of communication” at a first computer without the need for the user to enter any cryptographic information.”

VirnetX’s claims the iPhone 4S, iPhone 4, iPad 2, iPod touch, and Macs that run Mac OS X 10.7 (“Lion”) infringe up the patent, which was published in 2007.
