Nidec Files Patent Infringement Lawsuit Against Samsung

Headquartered in Kyoti, Japan, Nidec Corporation has filed lawsuits in the Osaka District Court on July 30, 2008 against Samsung Electro-Mechanics Co., Ltd. (SEMCO), an electronic components manufacturer based in Korea, for infringement of three Japanese patents (No. 3344913, 3502266, 3688015) regarding Nidec’s spindle motors mainly used for CD/DVD drives.

Nidec has confirmed that certain disk drives currently sold in Japan use SEMCO’s infringing spindle motors and requests injunctions to preclude SEMCO from marketing such motors in the Japanese market.
