RFMD announces ITC lawsuit withdrawn by Peregrine

RF Micro Devices Inc of Greensboro, NC, USA says that Peregrine Semiconductor Corp of San Diego, CA, USA, a fabless provider of radio-frequency (RF) integrated circuits (ICs) based on silicon-on-sapphire (SOS), has filed a motion to voluntarily withdraw the lawsuit it filed against RFMD in the US International Trade Commission (ITC) in February.

The ITC investigation was based on complaints filed by Peregrine with the ITC on 14 February and 11 May alleging that certain RFMD devices infringe patents related to silicon-on-insulator (SOI) technology for RF ICs (hence violating section 337 of the Tariff Act of 1930). The investigation involved five Peregrine patents and 38 separate patent claims. Peregrine sought, among other remedies, an exclusion order preventing the importation and sale of infringing products in the USA.

RFMD believes that the decision by Peregrine to terminate the ITC proceeding is in response to developments in the case that have consistently validated RFMD’s long-standing position that no infringement of Peregrine’s patents occurred and that the validity of the asserted Peregrine patents is in doubt. RFMD states that it respects the intellectual property rights of others and takes care to avoid infringements.

RFMD claims that it has a strong intellectual property portfolio relating to RFICs and switching technology that it has developed over many years, adding that it plans to continue to defend its position in the companion case filed by Peregrine in April in the US District Court for the Southern District of California.
