USITC Institutes Section 337 Investigation of Certain Mobile Cellular Communications Devices

The U.S. International Trade Commission (Commission or USITC) voted to institute an investigation of certain mobile cellular communications devices. The products at issue in the investigation are described in the Commission’s notice of investigation.

The investigation is based on a complaint filed on behalf of Pantech Corporation of Seoul, Republic of Korea, on July 3, 2025. A supplement was filed on July 30, 2025. The complaint, as supplemented, alleges violations of section 337 of the Tariff Act of 1930 in the importation into the United States and sale of certain mobile cellular communications devices that infringe patents asserted by the complainant. The complainant requests that the USITC issue a limited exclusion order and cease and desist orders.  

The USITC has identified the following respondents in this investigation:
•    HMD America, Inc., Miami, Fla.
•    HMD Global, Espoo, Finland 
•    HMD Global OY, Espoo, Finland
•    Huizhou TCL Mobile Communication Co., Ltd., Guangdong, China
•    Lenovo Group Ltd., Beijing, China
•    Lenovo (United States) Inc., Morrisville, N.C.
•    Motorola Mobility LLC, Libertyville, Ill.
•    OnePlus Technology (Shenzhen) Co., Ltd., Guangdong, China
•    OnePlus USA Corp., Irving, Texas
•    Shenzhen Tinno Mobile Technology Corp., Guangdong, China
•    TCL Communication Ltd., Hong Kong
•    TCL Communication Technology Holdings Ltd., Guangdong, China
•    TCL Electronics Holdings Ltd., Hong Kong
•    TCL Industries Holdings Co., Ltd., Guangdong, China 
•    TCL Mobile Communication (HK) Company Ltd., Hong Kong
•    TCL Mobile International Ltd., Hong Kong
•    Tinno USA, Inc., Plano, Texas

By instituting this investigation (337-TA-1456), 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 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.
