Power technology firm Vicor has initiated a USITC 337 investigation against Delta Electronics, Quanta, and Foxconn over alleged patent infringement in AI server power systems.
What Happened
AI Power Supply Dispute: As AI chip power consumption rises, vertical power delivery (VPD) systems have become a focal point for both performance and patent litigation. Vicor has filed a 337 investigation with the USITC, alleging that products from Delta Electronics, Quanta, Foxconn, and Luxshare infringe on its proprietary power conversion technology, potentially leading to import bans if found in violation.
Scope of Patent Claims: The investigation centers on specific mechanical and electrical configurations of power conversion modules rather than a broad concept of vertical power delivery. By targeting the stacking and interconnect methods used in server hardware, Vicor has expanded the scope of the dispute to include both component manufacturers and system integrators, creating significant legal hurdles for the supply chain.
Taiwanese Firms' Defensive Posture: Delta Electronics and Vicor have a history of mutual patent litigation, reflecting a complex landscape of intellectual property in power conversion. Delta maintains a robust portfolio of its own circuit and structural patents, suggesting that Taiwanese manufacturers are prepared to defend their designs and leverage their own technological advancements in court.
Market Implications: The USITC investigation is expected to last between 12 and 16 months, with the outcome depending on whether specific products infringe on the asserted claims. The industry is now closely monitoring the evidence and potential outcomes, including the possibility of licensing agreements or engineering redesigns to mitigate the risk of import restrictions on AI server hardware.
