InnoScience (Suzhou) Technology Holding Co., Ltd. (Innoscience; ) is a Chinese semiconductor enterprise with public listing status, headquartered in Suzhou, Jiangsu.
It stands as the largest global integrated device manufacturer dedicated solely to Gallium nitride (GaN) technology.
Background
Established in 2015 in Zhuhai by Luo Weiwei, a PhD graduate in applied mathematics from Massey University and former NASA scientist with 15 years of experience, Innoscience focuses on cutting-edge GaN microchips that integrate GaN with silicon. The company commits substantial resources to research and development aimed at scaling the manufacture of GaN chips, wafers, and modules, which has led to persistent financial losses. The majority of its sales remain within the Chinese market.
At the beginning of 2022, Innoscience broadened its reach by initiating operations in both the United States and Europe. On 30 December 2024, it successfully conducted its initial public offering on the Hong Kong Stock Exchange, securing HK$1.4 billion and attaining a valuation of HK$27 billion.
Lawsuits
In July 2023, the United States International Trade Commission (USITC) launched an investigation into Innoscience following an intellectual property complaint filed by Efficient Power Conversion (EPC). By November 2024, the USITC determined that Innoscience had infringed EPC’s patent rights and issued a limited exclusion order preventing certain Innoscience chips from entering the U.S. market. Innoscience declared its intention to appeal this decision.
On 14 March 2024, Infineon Technologies initiated patent infringement litigation against Innoscience in the United States District Court for the Northern District of California. By June 2024, Infineon extended legal proceedings to include Innoscience’s German distributors and further expanded the California lawsuit in July to encompass Infineon’s affiliated entities. In January 2025, Innoscience responded by filing a countersuit against Infineon and its Chinese subsidiaries in Suzhou, alleging violations of two power chip patents.
Industry insiders report that Innoscience’s pricing strategy is approximately half that of competing global GaN firms, prompting EPC and Infineon to implement measures aimed at preventing a price war originating from China. This aggressive pricing approach poses challenges to international GaN supply chains as well as domestic Chinese competitors and may cause supply chain instability if original equipment manufacturer (OEM) partners shift allegiance due to cost considerations.
In March 2025, Innoscience secured a favorable ruling when the Patent Trial and Appeal Board invalidated EPC’s patent claims, potentially mitigating restrictions on chip imports.
