Infineon Technologies said it expanded its infringement lawsuit against Innoscience, adding claims against the company and affiliates for alleged infringement of three additional patents.
The expansion comes after the German chip maker in March launched a legal challenge against U.S. semiconductor company Innoscience in California relating to gallium nitride technology for the production of semiconductors.
The three additional patents also relate to gallium nitride technology owned by Infineon, the company said.
In addition, it lodged a complaint with the U.S. International Trade Commission containing what Infineon said were legal claims referring to the same four patents covered by the lawsuit.
Infineon is seeking a permanent injunction for the infringement of its U.S. patents.
Innoscience wasn’t immediately available for comment. Last month, the company denied Infineon’s infringement allegations and questioned the validity of its patents.
