Infineon sues Innoscience for patent infringement

This patent pertains to gallium nitride (GaN) technology, covering essential aspects of GaN power semiconductors that underpin the reliability and performance of Infineon’s unique GaN devices.

Infineon contends that Innoscience has infringed upon this specific patent by manufacturing, using, selling, and importing into the United States a range of products, including GaN transistors. These products find applications across various sectors such as automotive, data centres, solar energy, motor drives, consumer electronics, and other areas within automotive, industrial, and commercial fields.

“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.

Furthermore, on 24th October 2023, Infineon highlighted its acquisition of GaN Systems Inc., solidifying its status as a prominent entity in the GaN power sector. Infineon's portfolio includes approximately 350 patent families related to GaN technology. Market projections by Yole, in its Power SiC and GaN Compound Semiconductor Market Monitor Q4 2023 report, anticipate a 49% compound annual growth rate in GaN revenue for power applications, potentially reaching around $2 billion by 2028. GaN is recognised for its wide bandgap properties, offering superior switching performance that enables the development of more compact, efficient, and cost-effective power systems.

Back in May 2023, Efficient Power Conversion (EPC) also sued Innoscience in federal court and the International Trade Commission (ITC) for patent infringement, seeking damages and barring Innoscience from importing the alleged infringing suite of GaN products into the United States.
