SAN FRANCISCO Analog Devices Inc. (ADI) said Wednesday (Dec. 20) it has filed a patent infringement suit against Silicon Laboratories Inc. in U.S. District Court in Boston.
ADI's suit alleges that Silicon Labs' Si84xx family of products infringe multiple U.S. patents addressing physical construction and signaling techniques related to ADI's iCoupler digital isolation products. ADI further alleges that Silicon Labs' product datasheets infringe the copyright on ADI datasheets for the iCoupler products. The complaint seeks unspecified damages and a court-ordered injunction against future infringement by Silicon Labs.
In a statement, Margaret Seif, ADI vice president and general counsel, said the company has been awarded more than 10 patents in the area of isolation components. "We started investing in this technology in 1997 and began selling products based upon it in 2001," Seif said. "We are taking this action today to protect our intellectual property and our investment."
ADI (Norwood, Mass.) said it has corresponding patent applications related to its digital isolation products pending in several other countries.
