A U.S. district court has dismissed a patent infringement case against AEM Holdings (SGX:AWX) filed by the US arm of Japanese semiconductor company Advantest Corp (TYO:6857), according to a Thursday filing to the Singapore Exchange.
The court dismissed Advantest Test Solutions' complaint, which was filed in October 2025, after finding that it failed to adequately plead direct or indirect patent infringement.
The court, however, granted Advantest leave to file an amended complaint.
AEM said it does not expect the court's ruling to have any material impact on its business operations or financial position.
Shares of AEM were down nearly 8% in Thursday's afternoon trade.
