CrestaTech Files Patent Infringement Complaint With U.S. International Trade Commission

Tuesday, January 28, 2014

Cresta Technology Corporation filed a complaint with the U.S. International Trade Commission today charging that two silicon chip manufacturers, Silicon Laboratories and MaxLinear, infringe its patents covering technology used in television sets, receivers, and other components. The complaint also names as respondents four television set manufacturers because of their use of infringing silicon tuner chips.

In the complaint, CrestaTech accuses Silicon Laboratories, MaxLinear, Samsung Electronics Co., LG Electronics, Sharp Corp., Vizio, and their U.S. subsidiaries of unlawfully importing certain television sets, receivers, tuners and other components into the United States. In addition to calling for an investigation into the alleged violations, CrestaTech seeks an exclusion order that would halt the importation of the devices it claims feature technology that infringes its patents. The company also is seeking a cease and desist order to stop the marketing and sale of the devices within the United States.

The three CrestaTech patents in question cover technology that enables a single television receiver to process analog or digital television signals in multiple standards, making it possible for a television to work anywhere in the world. The patented technologies also eliminate the need for bulky traditional “can” tuners, substantially reducing the cost of developing thin, flat panel televisions.

“CrestaTech doesn’t just own these patents; it also practices them,” noted Genevieve Vose Wallace, a partner with Susman Godfrey LLP, which represents the company in the dispute, along with Adduci, Mastriani & Schaumberg. “The company has invested heavily in research and development in the United States, and its continued success depends on its ability to protect its proprietary technology by enforcing its patent rights.”
