Peregrine patent infringement complaints lead to ITC investigation

Peregrine Semiconductor has announced that the US International Trade Commission (ITC) has launched an investigation into whether RF Micro Devices (RFMD) products infringe certain Peregrine patents relating rf ics and switch technology. The investigation also includes Motorola Mobility and HTC Corporation, whose products incorporate the alleged infringing rf ics.

The investigation is based on complaints filed by Peregrine with the ITC in February and May this year, alleging that certain RFMD semiconductor devices infringe Peregrine patents related to silicon on insulator technology for rf ics. Five Peregrine patents and 38 separate patent claims are involved. The company is reportedly seeking an exclusion order preventing infringing products being imported and sold in the US. "We are very pleased that the ITC has taken this matter seriously and will investigate our complaints," said Jim Cable, Peregrine's president and ceo. "The employees of Peregrine have spent 20 years of intensive research and development activity to bring our proprietary UltraCMOS process and design innovations to the rf marketplace. We are steadfast in our position to protect that investment on behalf of all the stakeholders of Peregrine."
