Power-One Files Patent Infringement Suit

Camarillo-based power supply maker Power-One said this morning that it has sued Artesyn Technologies for patent infringement. The firm said that it filed suit in the United States District Court for the Eastern District of Texas, Marshall Division. The lawsuit covers two patents Power-One received in 2004, and alleges that Artesyn is infringing on the patents by selling a DC/DC converter for PMBus. Power-One said that it is seeking a permanent injunction against Artesyn along with compensatory damages. The company competes heavily with Artesyn in the power supply business.
