Apple, Samsung, HTC and Sony sued over graphics rendering patents

Sometimes, you have to go all-in. Why not sue all the leading smartphone makers at once? That's what Graphics Properties Holdings is doing, channeling the ghost (and intellectual back-catalogue) of Silicon Graphics. Filing six cases against Apple, Samsung, RIM, HTC, Sony and LG, the lawsuits reference floating point calculations for rendering graphics, something that the company received patent approval for only yesterday. GPH claims that several phones, including the iPhone, Galaxy S II and BlackBerry Torch, infringe on its intellectual property. Layman legal types can sniff around the patent in question at the source below.
