According to information sourced from the China Trade Remedy Information Network, the United States International Trade Commission (ITC) officially announced on October 9 its decision to commence a 337 investigation concerning specific vertical power transmission systems, their constituent components, and downstream computer systems (Investigation No.: 337-TA-1526). This move was prompted by a petition filed by U.S.-based Vicor Corporation on September 9, which claimed that the relevant products infringe upon its U.S.-registered patent No. 10,903,734. The corporation has requested the issuance of both a limited exclusion order and a cease-and-desist order. The companies subject to this investigation encompass a range of electronics manufacturing and semiconductor firms hailing from China, the United States, and Europe, including prominent names such as Luxshare Precision, Foxconn Industrial Internet, Hon Hai Precision Industry, Delta Electronics, Infineon, and Monolithic Power Systems. The products at the center of this investigation are predominantly utilized in data center servers, artificial intelligence, and cloud computing systems, where they play a crucial role in supplying power to AI accelerators, TPUs, GPUs, and CPUs.
