The U.S International Trade Commission has found that Huawei, Nokia, and ZTE did not violate a patent owned by InterDigital.
This was the preliminary decision reached by an administrative law judge. The full ITC will make a final decision on the matter in October. InterDigital is a patent-licensing firm and had sued the companies over intellectual property pertaining to power conservation and messaging in mobile devices.
LG was also named in the original suit, but settled with InterDigital. InterDigital was hoping the ITC would block the offending devices from entering the U.S.
