Vietnam’s Law on Intellectual Property (IP Law) has undergone continuous amendment in recent years, with the latest amendment issued at the end of 2025. Among the amended and supplemented provisions, the regulation that has perhaps attracted the most attention is a provision relating to the use of protected IP objects by artificial intelligence (AI) systems. Specifically, Article 7 of the 2025 IP Law introduces a completely new Clause 5, which reads in full as follows: “Organizations and individuals are permitted to use texts and data relating to intellectual property objects that have been lawfully published, and which the public is allowed to access, for the purposes of scientific research, experimentation, and training of artificial intelligence systems, provided that such use will not unreasonably affect the legitimate rights and interests of the authors and intellectual property rights holders in accordance with this Law. With respect to texts and data that are objects protected by copyright and related rights, the use of the texts and data as set forth herein must also be in accordance with the regulations of the Government.” Analyzing this newly added provision in the context of how it was conceived, as well as the challenges that still lie ahead, can provide some interesting insights. From Aspirations to Flight in Science and Technology From the end of 2024 and throughout 2025—the 50th anniversary of the country’s reunification—Vietnam witnessed numerous sweeping changes in many areas, including legislative development. It could be said that no sessions of the National Assembly have ever adopted as many laws, resolutions, and major policies as this one. The aspirations of the highest-level leadership have been concretized into major law and policy projects, which were drafted, developed, and passed at record speed. All of this was aimed at building a foundation for Vietnam to achieve

On June 6, 2025, the Superior People’s Court in Hanoi overturned a non-use cancellation decision by the Intellectual Property Office of Vietnam, a rare and impactful occurrence. In a ruling that may help clarify the enforcement of Vietnam’s IP Law, the court held that valid trademark use can be established through commercial arrangements where the brand owner maintains actual control over the use of the mark, and is not confined to relationships governed by a so-called “formal license agreement. Background: Cross-Border Use, Local Challenge A Singapore company owns a well-known brand of consumer products that has gained recognition across Southeast Asia. In recent years, the brand has been targeted by several unauthorized trademark filings in Vietnam. In one such instance, a local Vietnamese trading company—previously linked to the production and export of counterfeit goods to neighboring countries—filed a non-use cancellation against the Singapore company’s mark and sought to register it under its own name. If the cancellation had been upheld, it would have enabled a complete hijacking of the brand. The IP holder operates in Vietnam through a structured cross-border supply chain. Under an agreement between two related foreign entities, one of which managed regional operations, production orders were placed through a designated Vietnamese company. While the Vietnamese manufacturer was not a party to the agreement, its role in using the mark was recognized and governed by internal and commercial documentation. The Vietnamese manufacturer lawfully obtained the necessary permits, regulatory approvals, and customs clearances for producing the goods in Vietnam. These activities were supported by banking records and internal communications, evidencing active, continuous use of the mark in Vietnam. However, the IP Office concluded that this use did not meet the statutory criteria because the Vietnamese manufacturer did not have a direct license agreement with the brand owner, as
