Frequently labeled as a patent troll, VirnetX on Tuesday launched one of its more aggressive attacks by suing Apple (below) over a patent it had only just been granted. The company, which has sued Apple before, alleged that "at least" current iOS devices and Lion-equipped Macs were violating some claims of a patent for a "Method for Establishing Secure Communication Link Between Computers of Virtual Private Network," or a standard VPN connection. The patent had been granted just the same day, suggesting that the aim of the patent was only to sue others for profit.
