Force MOS Technology

Force MOS Technology Co., Ltd., often referred to as Force MOS, is a fabless semiconductor company headquartered in New Taipei City, Taiwan. Established in 2006, the company is publicly listed on the Taipei Exchange under the ticker 4923.TWO. As of March 2026, Force MOS Technology has a market capitalization of approximately $37.5 million and employs around 49 full-time staff, with a trailing 12-month revenue of $28.8 million as of December 2025.

The company specializes in the design, development, and sales of metal-oxide-semiconductor-field-effect-transistors (MOSFETs) and analog integrated circuits (ICs). Its product portfolio includes trench power MOSFETs, bipolar transistors, diodes, rectifiers, Schottky diodes, and various power management solutions like ESC and TVS devices. These components are utilized in a wide array of applications, including light electric vehicles, brushless DC motor control, notebook computers, mobile phones, LCD TVs, motherboards, power supplies, and digital cameras.

Force MOS Technology's patent litigation posture indicates a focus on asserting its intellectual property. The company has one tracked case as a plaintiff and zero as a defendant in our database. The sole tracked case, Force MOS Technology v. ASUSTek Computer, Inc. et al., was filed in 2022 in the plaintiff-friendly U.S. District Court for the Eastern District of Texas.

In February 2025, a jury in the Eastern District of Texas found ASUSTek Computer, Inc. guilty of willful infringement in the ASUSTek case, ordering them to pay $10.5 million in damages to Force MOS Technology. The asserted U.S. Patent No. 7,812,409, relates to an improved semiconductor device. Force MOS Technology has also been involved in other patent assertions, including against Inergy Technology Inc. and PANJIT International Inc., sometimes facing scrutiny regarding the validity and assignment of its patents.
