Inv. No. 337-TA-564
Contact: Peg O'Laughlin, 202-205-1819


The U.S. International Trade Commission (ITC) has voted to institute an investigation of certain voltage regulators, components thereof and products containing same. The products at issue in this investigation are integrated circuits, used in a variety of electronics products, that receive power from an unregulated voltage source such as a battery and provide a stable output voltage.

The investigation is based on a complaint filed by Linear Technology Corporation of Milpitas, CA, on February 17, 2006. 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 voltage regulators, components thereof and products containing same that infringe patents owned by Linear Technology. The complainant requests that the ITC issue a permanent exclusion order and a permanent cease and desist order.

The ITC has identified Advanced Analogic Technologies, Inc., of Sunnyvale, CA, as the respondent in this investigation.

By instituting this investigation (337-TA-564), the ITC has not yet made any decision on the merits of the case. The case will be referred to the Honorable 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 U.S. Trade Representative within that 60-day period.
