Renesas Technology Corp. (San Jose, CA), a joint venture between Hitachi Ltd. and Mitsubishi Electric Corp., has filed a motion for a preliminary injunction in the Tokyo District Court against Nanya Technology Corp.’s (Taiwan) Japan subsidiary for suspension of Nanya’s importation, marketing and sales of semiconductor memory products that Renesas believes infringe its semiconductor package related patent.
Renesas previously filed patent infringement lawsuits in the US District Court for the Northern District of California, on December 17, 2003, and in the Tokyo District Court, on February 26, based on the infringement of semiconductor memory related patents. Renesas asserted that after those lawsuits were filed, Nanya Japan continued to willfully import into Japan and to market and sell in Japan memory products covered by Renesas’ patents without a license from Renesas. Thus, Renesas Technology filed for the preliminary injunction to obtain legal relief sooner.
