TOKYO -- Power semiconductor chip maker International Rectifier Corp. has filed a lawsuit against Japan's Renesas Technology Corp. and its parent companies, Hitachi Ltd. and Mitsubishi Electric Inc. and is alleging patent infringement, according to a Reuters report Tuesday (September 30, 2003).
International Rectifier is seeking to force Hitachi and Mitsubishi to disband their Renesas joint venture, formed in April, and wants Hitachi to pay a licensing fee for using patented technology.
"There is a good chance that Hitachi infringed on our patents, and that would make us creditors seeking compensation for those violations," the report quoted and un-named International Rectifier official in Tokyo as saying.
The suit was filed with the Tokyo District Court on September 3 seeking nullification of Renesas, because, it claimed, Hitachi did not notify all creditors about the plan to spin-off chip making activities to form Renesas, in breach of Japanese commercial law.
"We have entered into appropriate legal proceedings to ensure that the joint venture is not nullified," the report quoted an un-named Hitachi spokesman as saying.
