US launches probe into Taiwan firms
The USITC launched a Section 337 investigation into 20 tech firms, including Hon Hai Precision, Delta Electronics, Quanta Computer, and Foxconn, over alleged patent infringement by Vicor Corp. The probe focuses on power delivery systems used in AI servers. Vicor seeks exclusion and cease-and-desist orders. The investigation could take 12-16 months. Delta Electronics stated it would respond legally and denied current product impact.
