Judge Consolidates Cases in Patent Infringement Actions Against RF Micro Devices

San Diego, California, May 6, 2013Peregrine Semiconductor Corporation (NASDAQ: PSMI), a fabless provider of high-performance radio frequency integrated circuits (RFICs), today announced that Judge Irma Gonzalez has consolidated the two lawsuits pending in U.S. District Court that allege the infringement of Peregrine patented intellectual property relating to RFICs and switching technology by RF Micro Devices, Inc. (RFMD).

The lawsuits filed in the U.S. District Court for the Southern District of California claim that certain RFMD products infringe Peregrine patents relating to silicon-on-insulator (SOI) technology for RFICs. Peregrine seeks, in addition to damages, to permanently enjoin RFMD from further infringement. Peregrine expects that consolidation of the cases will allow its infringement claims to move more efficiently towards trial and appropriate legal remedy.
