Rambus "Accused" of Not-Developing DDR, Other Industry Standards
[01/27/2012 09:40 PM]The U.S patent and trademark office has rejected claims of Rambus company over infringing intellectual property by companies that utilize technologies like DDR and other. In particular, the U.S. government abandoned so-called Barth patents that Rambus got as a result of an acquisition.
The Barth family of three patents include DDR, DDR2, DDR3, mobile DDR, LPDDR, LPDDR2 and GDDR3 memory controllers. An appeals board at the U.S. Patent and Trademark Office declared the patent invalid on January 24, according to a ruling posted on their website. The previous two were declared invalid in September, according to Reuters news-agency.
Rambus has already lost a case against memory manufacturers Hynix Semiconductor and Micron. Invalidation of Barth family of patents is more than a bad news for Rambus as now it will be unable to sue companies that manufacture or develop dynamic random access memory (DRAM) or develop memory controllers.
Rambus can appeal the latest decision from the PTO. "We're evaluating our options," said the company spokeswoman Linda Ashmore.
