TCL Historic Lawsuits
TCL, a prominent player in the consumer electronics industry, has faced a series of significant legal battles over the years. These lawsuits primarily revolve around intellectual property disputes with major technology companies such as LG, Ericsson, Samsung, and MPEG LA, as well as consumer protection issues involving deceptive advertising of its televisions. Here’s a breakdown of some of the key lawsuits that have shaped TCL’s legal landscape.
Patent and Intellectual Property Lawsuits
TCL has been involved in several high-profile patent disputes with other major tech companies over the years. These cases center around technologies related to LTE, OLED displays, and essential video compression patents, highlighting ongoing conflicts in the consumer electronics industry over intellectual property.
LG Electronics: LTE Patent Infringement (2019)
In 2019, LG Electronics filed a lawsuit against TCL in Germany, alleging that TCL had infringed on its LTE patents. The lawsuit claimed that TCL had used LG’s patented LTE technology in its smartphones and other devices without permission. In 2021, a German court ruled that TCL had indeed infringed on one of LG’s LTE patents, though TCL retained the right to appeal the ruling, potentially prolonging the legal battle.
Ericsson: Smartphone Patent Dispute (Settled in 2021)
TCL was also embroiled in a protracted patent dispute with Ericsson, primarily over smartphone technology. The litigation spanned several years and involved cases in both California and Texas. Ericsson won multi-million dollar rulings in both jurisdictions before the U.S. Court of Appeals for the Federal Circuit overturned these decisions in 2021. The settlement that followed resolved the patent dispute, although it underscored the ongoing tensions between the two companies over technology rights.
MPEG LA: AVC Patent Infringement (2020)
In 2020, MPEG LA, a consortium that manages essential patents for video compression technologies, filed lawsuits against TCL. The lawsuit alleged that TCL had used MPEG LA’s AVC (Advanced Video Coding) essential patents in its mobile phones and televisions without obtaining the necessary licenses. This lawsuit highlighted the importance of patent licenses in the tech industry and how companies must navigate complex intellectual property agreements.
Samsung: OLED Display Patent Dispute (2025)
In 2025, Samsung filed a lawsuit against TCL over alleged infringements on its OLED display patents. Samsung accused TCL of using its OLED technology without authorization, sparking yet another patent dispute between the two companies. This case, which continues to unfold, highlights the ongoing competition between major electronics manufacturers over cutting-edge display technology.
Cerence Inc.: Voice Technology Patent Dispute (2025)
In August 2025, Cerence Inc., a company specializing in voice technology, filed a complaint with the U.S. International Trade Commission (ITC) to stop the importation of TCL products that allegedly violated Cerence’s voice technology patents. The lawsuit focuses on TCL’s smart televisions that use voice-enabled technology. The outcome of this case could have significant implications for TCL’s smart TV offerings if it leads to an import ban or financial penalties.
Consumer Protection and Class-Action Lawsuits
In addition to intellectual property disputes, TCL has faced a series of consumer protection lawsuits, particularly regarding false advertising and misleading marketing practices related to its televisions. These class-action suits highlight the company’s challenges with consumer transparency and fair marketing practices.
Refresh Rate Claims: 2020 Class Action Settlement
One of the major class-action lawsuits filed against TCL in 2020 accused the company of deceptively advertising some of its televisions as having a 120Hz refresh rate when, in fact, they did not. Consumers argued that TCL misled them into believing they were purchasing televisions with superior refresh rates for smoother visuals, which were not actually present in the products. The case was settled in March 2025, with TCL agreeing to a $2.9 million fund to compensate affected customers.
QLED Claims: 2025 Lawsuits Over False Advertising
In 2025, TCL faced multiple class-action lawsuits in the U.S. related to its QLED television models. These lawsuits alleged that TCL falsely marketed its QLED TVs as including advanced quantum-dot technology, claiming that the technology would deliver superior picture quality and color performance. The complaints argue that either the quantum-dot technology was non-existent or not sufficient to provide the promised benefits. These legal actions raise questions about the company’s marketing practices and whether TCL has been accurately representing its products to consumers.
