LCD TVs and the Corning glass cases: what the ITC says its 2026 TCL order covers, and what is still open

The U.S. International Trade Commission (ITC) has ordered that LCD glass found to infringe two Corning patents stay out of the United States, along with products containing it, when it is made or imported by or for TCL's North American business and three companies in China. The order dates from August 6, 2026. A second Corning case against the same companies is still undecided. For anyone shopping for an LCD TV, the notices answer less than you might expect: none we read says which models are covered. This guide sets out what the order says, what it leaves unsaid and what could change.

What the August order says

The case is Investigation No. 337-TA-1441, brought by Corning Incorporated of Corning, New York. In a notice issued on August 6 and printed in the Federal Register on August 11, the Commission found a violation of Section 337 of the Tariff Act of 1930 on the two patents left in the case, U.S. Patent Nos. 8,642,491 and 8,640,498. The remedy has two parts. A limited exclusion order bars the unlicensed entry of infringing LCD glass substrates, and of products containing them, made by or for the respondents or their affiliates. A cease and desist order applies to TTE Technology, Inc., which does business as TCL North America.

Four companies are covered: TTE Technology; TCL China Star Optoelectronics Technology Co., Ltd. (CSOT); Caihong Display Devices Co., Ltd., which also operates as Irico Display Devices; and Xianyang CaiHong Optoelectronics Technology Co., Ltd. (CHOT). On one point the Commission went further than the administrative law judge who first heard the case, who had recommended no cease and desist order at all. On another it agreed: the bond during the review period is zero percent.

After a remedy is ordered, the U.S. Trade Representative has 60 days to approve it, disapprove it or take no action, the ITC says in a notice on the related case. Counted from August 6, that period would have ended around October 5, by our arithmetic. On November 6, we searched the Federal Register for later notices in the case and for U.S. Trade Representative notices mentioning Section 337 since August 1, and found none. That is our search, not an ITC statement, and it shows only what the Federal Register holds. The ITC's website refused our automated requests, so this guide rests on its notices as printed in the Federal Register, and we did not read the orders or the docket themselves.

Which TVs does it reach?

The investigation's stated scope runs from the glass to display panels and then to electronic devices containing it, “which are TVs, monitors, notebook and laptop computers, and tablets”. The public notices stop there. They do not list models, say which TCL sets contain the glass or estimate how many are affected. The order is tied to infringing, unlicensed glass, so, as we read it, a TV is not covered merely because it carries a TCL badge. The judge's April finding also split the accused products: it says the “615 Accused Products” infringe and the “616 Accused Products” do not, and the notice does not say what those groups contain.

TCL's US store page listed TV series on November 6. It says nothing about the case or about whose glass those sets use, so we name none of them here. We found no statement on the order from TCL, and Corning's news page refused our request.

LG Electronics U.S.A., VIZIO, Hisense USA and the two HKC companies were also named at the start. All of them left after settlements, which the notices do not describe. The remedies concern importing and selling, and the notices say nothing about sets already in people's homes.

A second case, still open

Investigation No. 337-TA-1433 began with both patent and trade-secret claims against the same group. Corning withdrew the patent claims, which left the trade secrets. On July 23, 2026, the judge in that case found a violation of Section 337 by each of Caihong Display, CHOT, CSOT and TCL, “by reason of misappropriation of certain trade secrets”, in the notice's words. On August 6, the judge recommended that, if the Commission agrees, it issue a limited exclusion order of about 5 to 6 years and a cease and desist order against TCL, with a 9.8 percent bond during the review period.

On the public record we could read, none of that is in force. On September 21, the Commission voted to review parts of the judge's decision: whether CHOT and CSOT violated the law, whether a statute of limitations bars relief, and what the judge said about Corning's efforts to keep its secrets. Chairman Doyle would not have reviewed the finding. Written submissions closed on October 13. The notice gives no target date for a decision, and we found no later notice as of November 6. Before ordering a remedy, the Commission must consider the public interest, including the effect on U.S. consumers.

What a buyer can and cannot tell

The notices give a buyer no way to tell whether a particular LCD set falls under the order, and they say nothing about prices. They also differ from a safety recall: these cases turn on patents and trade secrets, and no notice we read tells owners to do anything with a TV they already have. Any model-level detail would most likely sit in the ITC's docket, EDIS, where the notices say non-confidential documents can be viewed.

The second case is at the same kind of stage as the ITC case over ASUS and Plume Wi-Fi gear that we reported on in October: a judge's finding under review, with no order in place.
