“A new lawsuit has targeted Apple, Sony and Nintendo, for allegedly infringing on patents involving technology used in the iPhone, Wii and PS2, among others. The plaintiff, Shared Memory Graphics LLC, holds U.S. Patent No. 5,712,664 that describes a ‘shared memory graphics accelerator system,’” MacNN reports.

“The ’664 patent involves technology for enhancing graphics by integrating part of the frame-buffer storage space and the graphics accelerator on the same chip.,” MacNN reports. “The system also allows the frame buffer size to be expanded by separate memory components. The filing also cites a second patent that builds upon the ’664 claims.”

MacNN reports, “The attorneys accuse Apple of infringing on the patent by using the related technology in the iPhone and iPod touch. Both products utilize PowerVR MBX Lite systems, which allegedly combine on-chip and off-chip frame-buffer memory technology protected by the patent claims… The case is still in the very beginning stages, leaving the defendants time to fight for dismissal or negotiate licensing agreements.”
