Infineon boosts GaN IP as it wins latest court round with Innoscience
Cette publication existe aussi en Français
Both Infineon Technologies and Innoscience are boosting their patent portfolios in gallium nitride (GaN) as their court case continues.
Knowmade in France has highlighted 645 new patent families filed in the last three months, with Infineon Technologies accelerating its filings. ST and Innoscience showed consistent patenting efforts, placing them among the top seven applicants. Over 320 new patent families were granted, reflecting Innoscience’s strengthened IP position in power GaN.
Innoscience is securing Chinese patents and pioneering US patents for integrated circuits and advanced HEMT devices.
This comes as the District Court in Munich, Germany ruled in favour of Infineon in a first instance patent infringement case against Innoscience.
The Munich District Court found that Infineon’s patent was infringed by GaN products that Innoscience is offering in Germany. The decision in particular prohibits Innoscience from manufacturing, selling, or marketing the infringing products in Germany. Additionally, the decision requires Innoscience to pay damages to Infineon.
“The ruling is a testament to the strength of Infineon’s intellectual property and confirms Infineon’s commitment to vigorously defend its intellectual property against infringements,” says Johannes Schoiswohl, Senior Vice President and Head of Infineon’s GaN Systems Business Line.
Innoscience has been approached for comment on the decision.
Meanwhile Chinese microLED maker BOE has also been ramping up its IP activity significantly in the GaN electronics patent environment with Xidian University in China maintains its lead in patenting activity, nearly doubling its invention disclosures compared to Q1 2025.
In contrast, more than 220 patents expired or were abandoned this quarter, significantly impacting companies such as Wolfspeed, which has been transferring its RF GaN IP assets to Macom and last month entered Chapter 11 bankruptcy protection.
SpaceX also acquired all IP assets from Akoustis Technologies after its bankruptcy for RF front-end modules, while Axiro Semiconductor advanced its position with acquisitions from Renesas Electronics.
There have also been around 20 significant IP collaborations, with Cornell University’s joint filing with IHPP PAS and the US Navy’s initiatives with domestic universities.
