Recently, based on the unconditional withdrawal application of Ultravision Technologies, LLC, the US International Trade Commission (ITC) announced to terminate the investigation under the Section 337 of the U.S. Tariff Act on 11 Chinese LED producers who were accused of infringing Ultravision's patents of module LED display panels and components, ending an epic battle that had sparked industry-wide attention.

The 11 Chinese LED companies targeted are Shenzhen Unilumin and Shenzhen Absen Optoelectronic Company and other nine companies.

In March 2018, a list of 11 Chinese companies were alleged by Ultravision for having violated Section 337 of the U.S. Tariff Act of 1930 and Ultravision requested the ITC to issue a general exclusion order, a limited exclusion order and a restraining order. In May 2018, on the request of Ultravision, ITC decided to launch an investigation.

The Chinese companies then hired U.S. lawyers, who immediately analyzed and evaluated the situation after receiving the complaint. Working closely with legal, IP, sales and tech teams of the pertaining companies, they evaluated the patents in question, alleged products and devised defense strategies. All these moves enabled the Chinese companies a step ahead in the entire litigation proceedings.

On November 27, 2018, Ultravision filed a motion to ITC to withdraw the investigation. On January 31, 2019, the administrative judge of ITC approved the motion in a preliminary ruling (Order No.29). On February 21, ITC issued the final ruling to terminate the investigation and cease reexamination of preliminary ruling made by the said administrative judge, scoring a victory for the Chinese companies prevailed in this case.
