1 case as defendant.
MediaTek USA, Inc. is the U.S. subsidiary of MediaTek Inc., a major Taiwanese fabless semiconductor company headquartered in Hsinchu, Taiwan. Founded in 1997, the parent company is publicly traded on the Taiwan Stock Exchange (TWSE: 2454). MediaTek is one of the world's largest fabless semiconductor companies, reporting revenues of approximately $19.2 billion for 2025 (TTM) and employing over 20,000 people globally. The U.S. headquarters is in San Jose, California, with over 500 employees across several U.S. engineering and sales locations.
MediaTek is an operating company that designs and sells a wide range of systems-on-chip (SoCs) and integrated circuits. Its products power more than two billion devices annually. Major product lines include the "Dimensity" and "Helio" SoCs for smartphones, making it a leading mobile chipset supplier. The company also produces chipsets for home entertainment products like smart TVs and set-top boxes, connectivity solutions including its "Filogic" Wi-Fi chips, the "Genio" platform for IoT devices, and "Dimensity Auto" SoCs for automotive infotainment and driver-assistance systems.
Based on its litigation history of zero plaintiff cases and one defendant case, MediaTek USA's patent posture is that of an operating company defending itself against patent infringement claims. The lawsuit was filed in the U.S. District Court for the Western District of Texas, a common venue for patent litigation. This defensive posture is typical for a large technology manufacturer that is frequently a target for patent assertion entities.
The company's only tracked suit is Redstone Logics LLC v. MediaTek, Inc. et al., filed in January 2024. The plaintiff, Redstone Logics, is a non-practicing entity (NPE) that has sued other major chipmakers, including NXP, Qualcomm, and Apple, using patents related to multi-core processor architecture. The suit targeted MediaTek processors, such as the Dimensity 9000+, that utilize certain ARM-based architectures. According to patent litigation news service RPX, MediaTek and Redstone Logics filed a notice resolving the dispute in early 2025.
The lawsuit alleges that MediaTek's products with DynamIQ Shared Unit architecture infringe the '339 patent. A claim construction order was issued on February 21, 2025.
