The case was dismissed with prejudice by joint motion on August 11, 2025. All claims by Maxell against the ten TCL entities were terminated, with each party bearing its own costs. No infringement finding, validity ruling, or damages award was entered. The dismissal with prejudice means Maxell cannot re-assert these specific claims against the named defendants.

Maxell asserted six U.S. patents: US7924366B2, US10375341B2, US10650780B2, US10015558B2, US10219020B2, and US10321206B2. These patents cover television display signal processing, image quality rendering, and smart TV content delivery technology. The application dates span 2010 to 2019, reflecting a multi-generational portfolio built around TV technology evolution.

The accused products covered virtually the entire TCL U.S. smart TV lineup, including S-Series, Q-Class, C-Series, P-Series, D-Series, and premium XL Collection models ranging from 28 inches to 98 inches. Both entry-level and flagship QLED models were named, suggesting the asserted patents cover features present across standard smart TV architectures.

The dismissal with prejudice bars Maxell from re-filing these specific claims against the named TCL entities in any U.S. court. However, all six patents remain valid and enforceable against third parties. Maxell retains full ability to assert these patents against other TV manufacturers, retailers, or importers not named in this action. The resolution is consistent with a confidential licensing agreement, though no financial terms are publicly disclosed.

The Eastern District of Texas is a historically plaintiff-favourable patent forum with experienced patent litigation infrastructure and an established local rules framework for complex IP cases. It has been a preferred venue for IP licensing entities — including Japanese patent assertion firms like Maxell — asserting portfolios against consumer electronics manufacturers with U.S. sales. TCL’s extensive U.S. retail presence likely established sufficient venue nexus.
