March 28, 2008 - In a lawsuit filed by Hynix Semiconductor and two other firms (Micron, a U.S. company, and Nanya, a Taiwanese company), a court in San Jose, California decided that Rambus did not violate an anti-trust law with its patent on DRAM manufacturing technology.
However, the U.S. Federal Trade Commission accepted the opinion of the global chip industry and had recently made a tentative decision that Rambus violated anti-trust laws. It's quite possible that all chipmakers use Rambus' patented technology, so the industry has been watching the Rambus v. Hynix case carefully.
I wonder when the next patent infringement case will be for these 2 companies. Time will only tell on more and more patents.
