Infineon Technologies AG filed a lawsuit, through its subsidiary Infineon Technologies Austria AG, against Innoscience (Zhuhai) Technology Company, Ltd., and Innoscience America, Inc. and affiliates. Infineon is seeking permanent injunction for infringement of a United States patent relating to gallium nitride (GaN) technology owned by Infineon.
The patent claims cover core aspects of GaN power semiconductors encompassing innovations that enable the reliability and performance of Infineon’s proprietary GaN devices. The lawsuit was filed in the district court of the Northern District of California.
Infineon alleges that Innoscience infringes the Infineon patent mentioned above by making, using, selling, offering to sell and/or importing into the United States various products, including GaN transistors for numerous applications, within automotive, data centers, solar, motor drives, consumer electronics, and related products used in automotive, industrial, and commercial applications.
“The production of gallium nitride power transistors requires completely new semiconductor designs and processes”, said Adam White, President of Infineon’s Power & Sensor Systems Division. “With nearly two decades of GaN experience, Infineon can guarantee the outstanding quality required for the highest performance in the respective end products. We vigorously protect our intellectual property and thus act in the interest of all customers and end users.”
Infineon has been investing in R&D, product development and the manufacturing expertise related to GaN technology for decades. Infineon continues to defend its intellectual property and protect its investments.
On 24 October 2023, Infineon announced the closing of the acquisition of GaN Systems Inc., becoming a leading GaN power house and further expanding its leading position in power semiconductors.
Infineon leads the industry with its GaN patent portfolio, comprising around 350 patent families. Market analysts expect the GaN revenue for power applications to grow by 49% CAGR to approx. US$2 billion by 2028 (source: Yole, Power SiC and GaN Compound Semiconductor Market Monitor Q4 2023). Gallium nitride is a wide bandgap semiconductor with superior switching performance that allows smaller size, higher efficiency and lower-cost power systems.
