The U.S. International Trade Commission (USITC) officially announced on October 9, 2026, the initiation of a "Section 337 investigation" targeting specific vertical power transmission systems, related components, and computing devices equipped with this technology. This investigation aims to determine whether the relevant products infringe upon patent rights within the United States. If a final ruling of infringement is made, the products in question could face exclusion orders, preventing them from entering the U.S. market, which would have far-reaching implications for the global technology supply chain.

The scope of this investigation is broad, involving 20 iconic enterprises in the global technology industry. Taiwan's tech sector is under high scrutiny, with industry leaders such as Foxconn, Delta Electronics, and Quanta Computer included in the investigation list. Meanwhile, international giants such as Luxshare Precision from mainland China, Infineon from Germany, and Flex from the United States are also among those named. In response to this sudden development, Taiwan's Ministry of Economic Affairs has publicly responded, stating that it will continue to track the progress of the case and maintain close contact with the affected Taiwanese firms, providing necessary legal consultation and administrative assistance as needed to ensure the rights and interests of Taiwanese manufacturers.

According to currently available public information and relevant media reports, attention from all sectors has focused on the patent ownership and market application of "vertical power transmission technology." This technology plays a critical role in current computing device and server architectures. With the infrastructure demand driven by the global AI boom, power transmission efficiency has become the core of competition in technology hardware. Most of the companies included in this investigation are key suppliers in the global AI supply chain.

The "2026 Financial Stability Report" released by the ASEAN+3 Macroeconomic Research Office (AMRO) points out that Asian economies are currently highly integrated into the global AI supply chain. If the export of tech products is hindered by patent disputes or reversals in market demand, it could trigger a chain reaction of volatility in financial markets and the real economy. Although a Section 337 investigation is a legal procedure, its potential trade-restrictive effects have compounded existing global economic concerns regarding the stability of the AI industry.

Although media outlets have reached a consensus regarding the initiation date of the "Section 337 investigation" and the list of involved companies, details concerning specific infringement claims, the plaintiff's demands, and the extent of the impact on each manufacturer remain in the early stages of information disclosure. Media reports indicate that the technical definition of "vertical power transmission systems" awaits further public documentation from the USITC to clarify which specific product lines of each manufacturer are involved. Furthermore, while the Ministry of Economic Affairs has stated it will intervene to assist, there is no conclusion yet on whether manufacturers are prepared with legal defense strategies or whether the investigation will cause substantial disruption to upcoming fourth-quarter tech product shipments.

All parties are closely observing the administrative orders subsequently issued by the USITC to assess whether temporary exclusion orders for specific products will be implemented.

The direct impact of this event on the global tech industry lies in supply chain stability and compliance costs. For Taiwanese manufacturers, as Foxconn, Delta Electronics, and Quanta are major global suppliers of servers and computing devices, any obstruction of their products in the U.S. market due to patent disputes would directly affect their revenue performance and delivery schedules for global clients. At the same time, this highlights the importance of patent deployment and technical compliance in the AI hardware arms race.

For the Central Asian region, although its current participation in the tech manufacturing industry differs from that of the aforementioned giants, as the five Central Asian nations actively promote infrastructure construction and digital transformation along the Silk Road, any drastic fluctuation in the global supply chain could indirectly affect the procurement costs and the difficulty of acquiring technology for imported international advanced computing devices.

Despite the market's cautious reaction to this investigation, experts warn against over-interpreting it as a full-scale escalation of a global tech trade war. A Section 337 investigation is a routine patent protection mechanism in the U.S. tech industry, aimed at maintaining competitive order in the U.S. market. The scope of restrictive clauses is usually limited to specific patented technologies rather than a blanket ban on specific enterprises. Therefore, before a final ruling is issued, there remains room for relevant companies to engage in settlements, licensing negotiations, or technical workarounds. Linking this single patent lawsuit to the risk of a collapse in the global AI boom may lead to unnecessary panic in market sentiment.

The most critical focus at present is how the investigated companies clarify infringement concerns through legal proceedings, and whether the U.S. Department of Commerce and the USITC will consider the interconnectedness of the global supply chain to adopt a more flexible approach during subsequent proceedings.

Subsequent observations will focus on three aspects: First, whether the USITC will issue a preliminary ruling on specific products involved, and whether that ruling includes temporary measures to prohibit imports; second, whether the 20 tech giants involved will form a joint legal team for defense or adopt individual settlement strategies; and third, whether Taiwan's Ministry of Economic Affairs and relevant industry associations will propose more specific technical compliance guidelines for such cross-border patent litigation to assist Taiwanese firms in reducing the risk of facing similar trade barriers in the future.

Furthermore, as global economic reliance on AI infrastructure continues to rise, government autonomy and patent deployment regarding critical power transmission technologies are expected to become important bargaining chips in future international trade policies.
