MaxLinear Files Declaratory Judgment Action Against Silicon Labs

CARLSBAD, Calif.–(BUSINESS WIRE)–May. 14, 2012– MaxLinear Inc., (NYSE: MXL) a leading provider of integrated radio-frequency (RF) and mixed-signal semiconductor solutions for broadband communication applications, announced today that it has filed a declaratory judgment complaint in United States District Court against Silicon Laboratories, Inc. as defendant to obtain a ruling that MaxLinear products, such as the MxL301 and MxL601 tuner ICs, do not infringe nineteen (19) patents owned by the defendant. The declaratory judgment complaint further seeks a ruling that the defendant’s patents are invalid.

“MaxLinear is a strong believer in intellectual property and respects the intellectual property rights of other companies. MaxLinear has invested millions of dollars in research and development to create its industry leading tuner technology and to obtain fundamental patents covering its unique tuner technology,” said Dr. Kishore Seendripu, CEO of MaxLinear.

“MaxLinear filed today’s declaratory judgment action in response to Silicon Labs’ false allegations to our customers that MaxLinear’s products infringe their patents,” Dr. Seendripu continued. “We had requested that they refrain from making these false and damaging allegations to our customers and to provide us with the factual basis for their infringement allegations. Instead, they have continued to threaten our customers with false allegations of patent infringement in hopes of disrupting customer relationships and hiding the fact that their products cannot match the performance of MaxLinear products, such as the MxL601. MaxLinear filed the declaratory judgment action to obtain confirmation that MaxLinear products do not infringe any of their patents.”
