On April 24, 2025, a patent infringement complaint was filed in the United States District Court for the Eastern District of Texas (Case No. 2:25-cv-00440), by two IPValue Management, Inc. subsidiaries—Longitude Licensing Ltd. and 138 East LCD Advancements Ltd.—against BOE Technology Group Co. Ltd. and LG Electronics Inc. The complaint is focused on the claimed unauthorized use of patented display technologies in a number of LG electronic products.
The plaintiffs claim infringement of 3 United States patents: U.S. Patent Nos. 8,391,020, 8,319,512, and 7,636,146. The patents in suit relate to advanced electro-optical and liquid crystal display technologies, many of which are essential to the operation and efficiency of contemporary high-resolution displays.
The accused products, according to the filing, include:
1. BOE-made LCD panel (part number MV270QUM-N50), used in the LG 27" 4K UHD IPS display (Model 27SR73U).
2. The LG 27" 4K UHD IPS display (Model 27SR73U) itself.
3. The LG 55" 4K UHD television (Model 55UT7570PUB).
4. A series of OLED display panels and modules.
These products, the plaintiffs assert, employ key technologies protected by the asserted patents without license or permission. The complaint demands relief for what the plaintiffs view as continuing infringement.
Summary of the Patents in Question
U.S. Patent No. 8,391,020
The patent describes an architecture of an electro-optical device with multiple circuit substrates and terminal connections to improve the electrical performance and simplify interconnect complexity. It has an electro-optical panel with predetermined terminal groupings and connection wirings to provide effective transmission of signals in display modules.
U.S. Patent No. 8,319,512
This invention pertains to a flexible display substrate configuration that incorporates inspection electrodes to observe and output signals processed within an embedded integrated circuit. This technology is important for quality control and performance monitoring of flexible and miniaturized display systems.
U.S. Patent No. 7,636,146
This patent refers to an arrangement in liquid crystal display (LCD) panels in which terminal groups are distinguished by size and function to maximize the performance of image and driving signals. The design reduces signal degradation and improves clarity in high-resolution display systems.
Background of Parties Involved
Longitude Licensing Ltd. and 138 East LCD Advancements Ltd. are owned by IPValue Management, Inc., an intellectual property monetization company. IPValue collaborates with patent owners to manage, license, and enforce high-value IP portfolios internationally.
BOE Technology Group Co., Ltd., which has its headquarters in China, is a leading worldwide manufacturer of display panels, supplying displays for a range of devices that include smartphones to television sets.
LG Electronics Inc., a South Korean multinational, is one of the world's leading consumer electronics producers, famous for its televisions, monitors, and OLED display technologies.
Legal Landscape and Jurisdiction
The Eastern District of Texas has long been established as a leading venue for patent litigation in the United States. Famous for its patent holder-friendly practices and seasoned judiciary, it continues to be a forum of choice for IP enforcement actions, particularly in sophisticated technology-related cases.
Here, the plaintiffs claim that BOE and LG Electronics are concurrently liable as the display panels by BOE were used in the end products by LG. Only time will tell how each of the defendants would react, but such suits end up leading to prolonged litigation, possible licensing agreement, or settlement based on what evidence and allegations are presented.
Potential Implications
Although the result of this litigation is unclear, the case serves to underscore the ongoing tensions in the display technology market, where businesses continue to pour money into innovation while operating within the competitive and litigious climate of intellectual property.
In case the court decides in favor of the plaintiffs, this could result in injunctive relief, monetary damages, or forced licensing of the patented technologies. On the other hand, settlement out of court may take place if the parties choose a mutually acceptable solution.
This lawsuit also supports the strategic function of IP licensing and assertion entities such as IPValue in enforcing patents on behalf of inventors, research institutes, and portfolio owners. These types of firms have a significant role in guaranteeing respect for technological innovation and just compensation in commercial markets.
As the case unfolds, players in the display manufacturing and consumer electronics sectors will be watching closely, considering the possible implications for patent enforcement habits, licensing conventions, and product development tactics.
As the legal process continues, additional updates will be given based on filings, court rulings, and any significant developments in the case.
