Apple, Sony, HTC, LG, Research In Motion (RIM) and Samsung are all being sued by Graphics Properties Holdings (GPH), formerly known as Silicon Graphics Inc. (SGI), for allegedly infringing a graphic processing patent on certain of the companies’ mobile devices.

According to Reuters, individual lawsuits were filed against each of these six companies, with all six complaints having been filed with the US District Court of Wilmington, Delaware.

The graphics processing patent at issue relates to a computer graphics process, which turns text and images into pixels that can be displayed on a device’s screen. GPH is seeking a sales ban on these devices as well as “reasonable” royalties and other damages.

GPH asserts that Apple’s infringing devices include the iPhone, whilst the Sony Ericsson Xperia Play, HTC’s EVO 4G, LG’s Thrill, Research in Motion’s Torch smartphones, as well as Samsung’s Galaxy S and Galaxy S II smartphones are all in allegedly in violation of this patent.

In other patent related news, Facebook recently acquired a grand total of 750 patents from International Business Corp (IBM), in order to beef up its patent portfolio for its patent battle with Yahoo!.
