Response to Infineon’s lawsuit against Innoscience

Infineon filed this lawsuit in a US district court in California on March 13, 2024, and asserted a single US 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 characterisation 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 has 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 centres 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.
