Patent Suit Adds Intel, AMD

A patent holding company is expanding its patent infringement lawsuit to Intel and AMD .

Lawyers for Acacia Research filed additional paperwork with the U.S. District Court for the Central District of California asking that the two chipmakers be added to a patent infringement case currently pending in the Calif. court.

The suit centers on Acatia's Computer Memory Cache Coherency technology, which connects peripheral devices with cache memory to communicate with the main computer memory.

Acacia said its technology lets different memories communicate and synchronize with each other, allowing peripheral devices to operate at faster speeds.

The technology is currently used in desktop, notebook, and server computer systems.

Intel spokesman Chuck Mulloy told internetnews.com that the company had evaluated Acacia's claims and found the allegations are "without merit." Mulloy said Intel would defend itself "vigorously" against the lawsuit.

A spokesperson with AMD was not immediately available to comment on the suit.

Acacia filed the original suit against Via Technologies back in December 2004 and said it would more than likely consolidate the lawsuits for pretrial purposes. In its statement to the press, Acacia remained vague on exactly what it wants from Intel and AMD.

Newport Beach, Calif.-based Acacia is made up of Acacia Technologies group and CombiMatrix group. The conglomerate makes its living acquiring and licensing patent rights to various technologies related to digital audio-on-demand and video-on-demand transmission.

As internetnews.com previously reported, the company began making waves in 2003 when it claimed it pretty much owned streaming media and managed to shut down five X-rated sites with an injunction.

Last year, the company set its sights on the telecommunications and wireless industries claiming companies like Verizon infringed on its digital media transmission (DMT) patents.

If it holds up in court, Acacia's patent would be more detrimental to Intel than to AMD. Industry reports tracking 2003 sales of core logic chipsets by all manufacturers indicate total annual sales of approximately $4 billion, with Intel holding the largest market share.
