1 case as defendant.
ASUSTeK Computer Inc., commonly known as ASUS, is a Taiwanese multinational computer hardware and consumer electronics company headquartered in Beitou District, Taipei, Taiwan. Founded in 1989, ASUS is a publicly traded company on the Taiwan Stock Exchange (TWSE: 2357). As of late 2025, the company reported a trailing 12-month revenue of approximately $23.7 billion and had over 17,000 employees worldwide. Its market capitalization was around $15 billion as of May 2026.
ASUS manufactures and sells a wide range of products, including desktop computers, laptops (such as ZenBook, VivoBook, TUF Gaming, and Republic of Gamers (ROG) series), mobile phones (ZenFone, PadFone), networking equipment, monitors, Wi-Fi routers, projectors, motherboards, graphics cards, and other peripherals. The company is recognized as a top global vendor for motherboards and a leading consumer notebook vendor. ASUS also operates as an original equipment manufacturer (OEM) and provides software services for system updates, hardware adjustments, and customer support via its MyASUS platform.
In terms of patent litigation, ASUS exhibits the posture of an operating company defending against infringement claims. The company has been recorded as a defendant in one tracked case and has no appearances as a plaintiff. This activity aligns with typical operating companies that are targets of patent assertions rather than entities primarily asserting patent rights.
The sole tracked case involving ASUS is Force MOS Technology v. ASUSTek Computer, Inc. et al., filed on November 28, 2022, in the Texas Eastern District Court. This particular venue is known for being a favored jurisdiction for patent plaintiffs.
A jury awarded Force MOS $10.5 million for infringement of four claims from two trenched MOSFET patents, including US7629634. A final judgment was entered, and a bench trial on ASUSTek's inequitable conduct claims also favored Force MOS. Post-judgment issues remain.
