The U.S. International Trade Commission (ITC) has voted to institute an investigation of certain power amplifier chips, broadband tuner chips, transceiver chips, and products containing same. The products at issue in this investigation are high performance integrated circuits used in a variety of products, including single-chip cable modems, radio receivers, tuners, set-top boxes, wireless headsets, wireless modems, and other telecommunications devices.

The investigation is based on a complaint filed by Broadcom Corporation of Irvine, CA, on March 3, 2003, and supplemented on March 19 and 28, 2003. The complaint alleges violations of section 337 of the Tariff Act of 1930 in the importation into the United States, the sale for importation, and the sale within the United States after importation of certain power amplifier chips, broadband tuner chips, transceiver chips and products containing same that infringe patents owned by Broadcom. The complainant requests that the ITC issue a permanent exclusion order and a permanent cease and desist order.

The ITC has identified Microtune, Inc., of Plano, TX, as the respondent in this investigation.

By instituting this investigation (337-TA-490), the ITC has not yet made any decision on the merits of the case. The case will be referred to Sidney Harris, an ITC administrative law judge, who will schedule and hold an evidentiary hearing. Judge Harris will make an initial determination as to whether there is a violation of section 337; that initial determination is subject to review by the Commission.

The ITC will make a final determination in the investigation at the earliest practicable time. Within 45 days after institution of the investigation, the ITC will set a target date for completing the investigation. ITC remedial orders in section 337 cases are effective when issued and become final 60 days after issuance unless disapproved for policy reasons by the President of the United States within that 60-day period.
