Rambus sues IBM despite U.S. PTO intervention
Bangalore: Chip firm, Rambus has sued IBM as part of efforts to overturn a court ruling that IBM had not infringed one of its memory patents. In a lawsuit filed recently in the federal court in San Jose, California, Rambus said the U.S. Patent and Trademark Office (PTO) erred through a series of decisions in finding that a patent application assigned to IBM did not interfere with its own patent obtained at the end of 2002. "The board committed errors of fact and law in its orders, decisions, and judgment," Rambus said in its complaint. This is not the first time Rambus has sued a rival over patent infringement. Most recently it has been in a bitter battle with Nvidia, which Nvidia eventually lost at the end of July. Nvidia threatened to appeal the ITC ruling, but eventually signed a deal with Rambus earlier this month.
