Advanced Analogic Tech Receives Favorable Initial ITC Decision in Dispute With Linear Tech

May 30, 2007 by Jeff Shepard

Advanced Anologic Technologies Inc. (AATI) received favorable news from the U.S. International Trade Commission (ITC) investigation to determine whether or not its charge pump and switching regulator products infringe on Linear Technology Corp.’s patents. The Administrative Law Judge for the ITC issued his initial determination that Linear’s U.S. Patent Nos. 6,411,531 and 6,580,258 were either non-infringed or invalid. The initial determination will be considered by the full ITC, and the final ruling is expected to be issued by September 22, 2007.

Linear had claimed that AATI’s products infringed on two of its patents and contacted many of AATI’s customers, threatening legal action for continued use of the products. AATI responded by suing Linear in February 2006 for unfair business practices, interference with existing and prospective customers, and trade libel, as well as a declaration of patent invalidity and non-infringement. Linear then filed a petition with the ITC requesting an investigation into whether or not the related AATI products violate U.S. Patent Nos. 6,411,531 and 6,580,258. The ITC responded to the request in March 2006 and began its investigation. AATI’s lawsuit against Linear is currently stayed pending the outcome of the ITC’s investigation.
