Longitude Licensing Ltd. v. BOE Technology Group Co. Ltd., 2:23-cv-00515, E.D. Tex.

In January 2026, a federal jury in the U.S. District Court for the Eastern District of Texas delivered a decisive victory for Robins Kaplan clients Longitude Licensing Ltd. and 138 East LCD Advancements Ltd., finding that display manufacturer BOE Technology Group Co., Ltd. willfully infringed three foundational LCD display patents and awarding $66.9 million in damages.

The jury found that BOE willfully infringed U.S. Patent Nos. 7,705,948, 8,223,093, and 10,181,462, which cover core liquid crystal display technologies that originated from the research and development work of industry leader Seiko Epson, and are used in high-volume products such as monitors, TVs and laptops. The asserted patents relate to structural optimizations in LCD pixel arrays and protective circuitry in semiconductor display devices.

The lawsuit, filed in November 2023, asserted direct and indirect patent infringement and included technical and damages evidence targeted at LCD panel products distributed by BOE, which is among the largest manufacturers of LCD panels in the world.

At trial, the jury found that BOE infringed all three asserted patents and that its infringement was willful. The jury also determined that BOE failed to prove the patents were invalid. The award comprised lump sum damages of approximately $29 million for each of the ’948 and ’462 patents and about $7.5 million for the ’093 patent, totaling $66.9 million.
