Macom granted preliminary injunction against Infineon

US court rules in favour of Macom on GaN-on-silicon rights

Macom, a US company that makes RF, microwave and photonic semiconductors, has been granted a preliminary injunction in its lawsuit against Infineon Technologies Americas Corp over GaN-on-silicon technology rights.

The US District Court for the Central District of California in Los Angeles' decision confirmed Macom's continuing exclusive rights in certain GaN-on-Si RF fields under a 2010 License Agreement entered into between Nitronex (acquired by Macom in 2014) and International Rectifier (acquired by Infineon in 2015); and it ruled that Macom is likely to succeed on its claim that Infineon's purported termination of that Agreement was improper and without effect.

It granted Macom's motion for a preliminary injunction prohibiting Infineon from engaging in activities inconsistent with the 2010 License Agreement pending the Court's final decision in the case.

"We were forced to file this lawsuit to stand up to Infineon's bullying and anticompetitive behavior. We are gratified by the Court's preliminary decision confirming that the GaN-on-Si rights granted to us under the 2010 License Agreement remain in full force and effect and that Infineon acted improperly in trying to operate in our exclusive field of use," said John Croteau, president and CEO of Macom.

"We are firmly committed to vigorously litigating this case to its rightful conclusion. We continue on the path to providing GaN-on-Si technology that promises to improve network data service and cell coverage of 4G/LTE and 5G basestations that will benefit people worldwide."
