Respondents include LG Electronics, VIZIO, MediaTek, and Sigma Designs, Inc. (SDI). Achieved settlement with LG prior to the conclusion of expert discovery. Following the evidentiary hearing, the presiding ALJ issued an initial determination finding a violation of Section 337 and recommending the imposition of an exclusion order against the remaining Respondents’ accused products. The ITC affirmed the ALJ’s finding of a violation on August 22, 2018. As a result, the Commission issued orders banning the importation of products made by VIZIO, MediaTek, and SDI and cease and desist orders against VIZIO and SDI.
