Company profile

MediaTek Inc. is a major fabless semiconductor company from Taiwan that designs and markets a wide range of semiconductor products. Founded on May 28, 1997, as a spin-off from United Microelectronics Corporation (UMC), MediaTek is headquartered in Hsinchu, Taiwan. The company is publicly traded on the Taiwan Stock Exchange (TWSE: 2454). As a leading global entity in its sector, MediaTek powers over two billion devices annually. For its fiscal year ending in December 2025, the company reported revenues of approximately $19.1 billion, and it employs over 17,000 people.

MediaTek is a leading developer of innovative systems-on-chip (SoC) for a variety of devices, including mobile phones, home entertainment systems, and Internet of Things (IoT) products. The company’s product lines include the "Dimensity" family of 5G smartphone chips, "Helio" processors for 4G smartphones, "Kompanio" chips for Chromebooks, and "Pentonic" SoCs for smart TVs. MediaTek also develops chipsets for Wi-Fi connectivity ("Filogic"), IoT devices ("Genio"), and provides custom ASIC design services. The company has a significant market share, having become the largest smartphone chipset vendor by volume in 2020.

As an operating company, MediaTek is typically a defendant in patent litigation. The provided case data shows MediaTek as a defendant in one U.S. patent suit and as a plaintiff in none. This defensive posture is common for large technology manufacturers that are frequently targeted by patent assertion entities. The single tracked case, Redstone Logics LLC v. MediaTek, Inc. et al., was filed in the U.S. District Court for the Western District of Texas, a popular venue for patent litigation. This case reflects MediaTek's position as a target for patent assertions related to its high-volume product lines.
