The U.S. International Trade Commission (USITC) voted to institute an investigation of certain liquid crystal devices, components thereof, and products containing same. The products at issue in the investigation are described in the Commission’s notice of investigation.

The investigation is based on a complaint filed by BH Innovations LLC of New York, New York on August 29, 2025. The complaint was amended on September 19, 2025, to add Longitude Licensing Limited of Ireland, and 138 East LCD Advancements Ltd. of Ireland as complainants. A supplement to the complaint was filed on September 25, 2025. The complaint, as amended and supplemented, alleges violations of section 337 of the Tariff Act of 1930 in the importation into the United States and sale of certain liquid crystal display devices, components thereof, and products containing same that infringe patents asserted by the complainants. The complainants request that the USITC issue a limited exclusion order and cease and desist orders. 

The USITC has identified the following respondents in this investigation:

• HKC Corporation Ltd., Shenzhen City, China
• Chongqing HKC Optoelectronics Technology Co., Ltd., Chongqing, China

By instituting this investigation (337-TA-1462), 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.
