LG Electronics Inc. is a major South Korean multinational electronics company headquartered in Seoul. Founded in 1958 as GoldStar, it is a public company and a key part of the LG Corporation conglomerate. The company is publicly traded on the Korea Exchange (KRX: 066570) and the London Stock Exchange (LSE: LGLD). LG Electronics employs over 74,000 people globally and reported worldwide revenues of over KRW 88 trillion in 2024.
As a global operating company, LG Electronics manufactures and sells a wide variety of consumer and commercial products. Its main business units are Home Appliance & Air Solution, Home Entertainment, Vehicle Component Solutions, and Business Solutions. Major product lines include televisions, home theater systems, refrigerators, washing machines, computer monitors, and automotive components. The company also provides commercial products such as digital signage, and HVAC systems.
The provided case data shows LG Electronics as a defendant in one tracked patent case, with no instances of it acting as a plaintiff. This posture is typical of a large operating company that is a target for patent litigation. The single tracked case, Multimedia Technologies Pte Ltd v. LG Electronics Inc, was an appeal at the Court of Appeals for the Federal Circuit. This appears to stem from a patent infringement lawsuit filed in the U.S. District Court for the Eastern District of Texas, a common venue for patent assertion.
The litigation with Multimedia Technologies Pte Ltd concerned patents related to smart TV technology used in products incorporating LG's webOS operating system. In May 2025, a jury found that LG did not infringe the asserted patents and also ruled that the patent claims were invalid, resulting in a victory for LG Electronics in the district court. The subsequent appeal at the Federal Circuit, listed in the authoritative case data, was later dismissed by agreement of both parties.
Proxense sued LG Electronics Inc. and LG Electronics U.S.A., Inc. in the Western District of Texas asserting U.S. Patent 10,698,989 as one of seven asserted patents, with claims 1-6 asserted. The case was stayed, with an order on motion to stay entered Feb. 17, 2026.

The case is pending; Proxense also separately asserted four other previously used patents against LG Pay and LG Wi-Fi 6/6E/7 products.
Maxell asserted nine U.S. patents, including U.S. 8,736,729, against LG smartphones, tablets, and Gram laptops. Originally filed in E.D. Tex., the case was transferred to N.D. Cal. and closed on July 2, 2025, after a stipulation of dismissal, consistent with a settlement.
