Inv. No. 337-TA-538
Contact: Peg O'Laughlin, 202-205-1819


The U.S. International Trade Commission (ITC) has voted to institute an investigation of certain audio processing integrated circuits and products containing same. The products at issue in this investigation are used in devices that receive and store digital information and convert that information to an audio output, including personal computers, DVD players, and portable MP3 players.

The investigation is based on a complaint filed by SigmaTel, Inc., of Austin, TX, on March 14, 2005, alleging 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 audio processing integrated circuits and products containing same that infringe patents owned by SigmaTel. The complainant requests that the ITC issue a permanent exclusion order and a permanent cease and desist order.

The ITC has identified Actions Semiconductor Co. of China as the respondent in this investigation.

By instituting this investigation (337-TA-538), the ITC has not yet made any decision on the merits of the case. The case will be referred to the Honorable Paul J. Luckern, an ITC administrative law judge, who will schedule and hold an evidentiary hearing. Judge Luckern 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.
