Innoscience Technology firmly denounces the accusations made by Infineon Technologies Austria AG in a recent patent infringement lawsuit against three Innoscience entities. Infineon filed this lawsuit in a U.S. district court in California on March 13, 2024, and asserted a single U.S. patent.
Innoscience denies Infineon’s allegations of patent infringement as well as the validity of the Infineon patent. Innoscience will vigorously defend itself and is confident that it will prevail. Infineon’s intention with this litigation is also in question, as it has asserted a patent that has significant defects. Particularly, even a cursory review of Infineon’s patent portfolio reveals that the alleged “invention” of the asserted patent was already disclosed in Infineon’s own earlier prior art patents, raising concerns that it may have committed fraud on the United States Patent and Trademark Office, for not making proper disclosures during the prosecution of the asserted defective patent.
In addition, contrary to Infineon’s wrong characterization that the claims of the asserted defective patent “cover core aspects of GaN power semiconductors,” the lawsuit only concerns a small fraction of Innoscience’s packaged high-voltage (650V-700V) GaN transistors and does not affect the vast majority of its other products (including unpackaged transistors and wafers, low-voltage transistors, and certain packaged transistors).
Therefore, the lawsuit should have little to no effect on Innoscience’s current ability to make, use, sell, offer to sell, or import into the United States its products for customers. Innoscience respects others’ valid IP rights and is also dedicated to developing its own IP portfolio. Despite being an eight-year old company, Innoscience has filed more than 800 patent applications globally. Innoscience’s R&D team boasts 500+ technical experts across the world.
Through continuing innovation, Innoscience has produced GaN devices to power a diverse range of products, from power delivery chargers to data centers and smartphones, showcasing its ability to align with evolving application demands and adapt to diverse customer specifications.
Moreover, Innoscience has always sought a cooperative and mutually beneficial approach to develop the global GaN industry, even among others in the same industry. Innoscience intends to prevail in this pending lawsuit and is determined to remain a trusted and reliable partner for its customers and contribute to their success by offering top-notch and versatile products and solutions based on Innoscience’s home-grown, superior technologies.

In August 2023, Navitas introduced a 3.2kW data center power platform utilizing latest GaN technology enabling over 100W/in3 and over 96.5% efficiency. Now, Navitas is releasing a 4.5kW platform enabled by a combination of GaN and SiC to push densities over 130W/in3 and efficiencies over 97%. These two platforms have already generated significant market interest with over 20 data center customer projects in development expected to drive millions in GaN or SiC revenues starting this year.
Today, Navitas also announces its plans to introduce an 8-10kW power platform by the end of 2024 to support 2025 AI power requirements. The platform will utilize newer GaN and SiC technologies and further advances in architecture to set all-new industry standards in power density, efficiency and time-to-market. Navitas is already engaged with major data-center customers, with full platform launch anticipated in Q4 ’24, completing this 3x increase in power demands in only 12-18 months.
Navitas’ unique data-center design center is creating these system designs to address the dramatic increases in AI data center power requirements, and assist customers to deploy platforms quickly and effectively to meet the accelerated time-to-market demands of rapid AI advances.
