RFMD, Motorola Mobility and HTC to be Investigated by U.S. ITC based upon Peregrine Semiconductor Patent Infringement Complaint

Peregrine Semiconductor Corporation (Peregrine), a leading provider of high-performance radio-frequency (RF) integrated circuits (ICs) today announced that the U.S. International Trade Commission (ITC) has launched an investigation into whether RF Micro Devices, Inc. (RFMD) products infringe certain Peregrine patents relating to RF ICs and switch technology. The action and investigation further include Motorola Mobility, Inc. and HTC Corporation (HTC), whose products incorporate the alleged infringing RF ICs. The investigation is based on complaints filed by Peregrine with the ITC on February 14, 2012 and May 11, 2012 alleging that certain RFMD semiconductor devices infringe Peregrine patents related to silicon-on-insulator (SOI) technology for RF ICs. The investigation involves five Peregrine patents and 38 separate patent claims. In the ITC action, Peregrine is seeking, among other remedies, an exclusion order preventing the importation and sale of infringing products in the United States.
