Innoscience (Zhuhai) Technology Company, Ltd., commonly known as Innoscience, is a publicly listed Chinese semiconductor company headquartered in Suzhou, Jiangsu, China, with manufacturing facilities in Zhuhai and Suzhou. Founded in 2015 by Dr. Luo Weiwei, a former NASA scientist, Innoscience is recognized as the world's largest Integrated Device Manufacturer (IDM) fully focused on Gallium Nitride (GaN) technology. The company went public on the Hong Kong Stock Exchange on December 30, 2024, raising HK$1.4 billion and achieving a valuation of HK$27 billion. As of April 30, 2026, Innoscience had 80 employees, and by 2023, its revenue reached CN¥593 million.
Innoscience specializes in the design, development, and manufacturing of GaN power devices and integrated circuits, utilizing an 8-inch GaN-on-silicon wafer mass-production line. Their product portfolio spans a wide voltage range (15V to 1200V) and includes wafers, discrete devices, bidirectional GaN, and power ICs. These products are used in various applications such as consumer electronics (fast charging, laptops, e-bikes), renewable energy (battery formation, motor drives), automotive systems (LiDAR, DC-DC power supplies), server power supplies, and robotics. Innoscience held a 29.9% share of the global GaN power device market by 2024. They have also partnered with companies like NVIDIA for AI data center power architectures and onsemi for GaN power portfolio rollout.
Innoscience is an active litigant, appearing as a plaintiff in its sole tracked case. This indicates an active posture in asserting its intellectual property. The company has been involved in significant patent disputes concerning GaN technology with Infineon Technologies.
Innoscience America, Inc. et al. v. Infineon Technologies North America Corp. is Innoscience's tracked case in the Patent Trial and Appeal Board (PTAB), filed on February 4, 2025. This PTAB action runs parallel to broader litigation between Innoscience and Infineon. Infineon initiated lawsuits against Innoscience in the US (California and ITC) and Germany, alleging infringement of GaN-related patents. In turn, Innoscience countersued Infineon in China. In the US, an ITC initial determination in December 2025 found Innoscience avoided all of Infineon's asserted patent claims, and while a later full ITC Commission affirmed infringement of one Infineon patent by Innoscience's legacy products, it also confirmed Innoscience's redesigned products did not infringe. Concurrently, Innoscience secured a significant victory in China, where the Supreme People's Court upheld a sales injunction against Infineon's GaN products in mainland China due to infringement of two Innoscience patents.
