Inv. No. 337-TA-698
Contact: Peg O'Laughlin, 202-205-1819


The U.S. International Trade Commission (USITC) has voted to institute an investigation of certain DC-DC controllers and products containing the same. The products at issue in this investigation are used to regulate DC power in electronic devices.

The investigation is based on a complaint filed by Richtek Technology Corp. of Hsinchu, Taiwan, and Richtek USA, Inc., of San Jose, CA, on December 2, 2009. The complaint alleges violations of section 337 of the Tariff Act of 1930 in the importation into the United States and sale of certain DC-DC controllers and products containing the same that infringe patents asserted by Richtek. The complainants also assert misappropriation of trade secrets. The complainants request that the USITC issue an exclusion order and a cease and desist order.

The USITC has identified the following as respondents in this investigation:

uPI Semiconductor Corp. of Taiwan;
Advanced Micro Devices, Inc., of Sunnyvale, CA;
Sapphire Technology Limited of Hong Kong;
Diamond Multimedia, Inc., of Chatsworth, CA; and
XFX Technology, Inc., of Ontario, CA.

By instituting this investigation (337-TA-698), the USITC has not yet made any decision on the merits of the case. The USITC's Chief Administrative Law Judge will assign the case to one of the USITC's six administrative law judges (ALJ), who will schedule and hold an evidentiary hearing. The ALJ 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 USITC will make a final determination in the investigation at the earliest practicable time. Within 45 days after institution of the investigation, the USITC will set a target date for completing the investigation. USITC 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.
