In March 2026, the Intellectual Property Office of Vietnam (IP Office) issued a decision refusing a trademark application after considering an opposition based primarily on copyright grounds. The outcome is noteworthy because the foreign brand owner had neither trademark registrations nor applications in Vietnam at the time the opposition was filed, and the IP Office has historically applied a stringent approach to oppositions relying on copyright. The Opposition Maurten is a well-known Swedish sports nutrition brand recognized globally for its innovative hydrogel technology, which is designed to help endurance athletes fuel more effectively without gastrointestinal discomfort. The brand’s distinctive logo is characterized by clean lines and a bold black-and-white color scheme, and has long been associated with the company’s performance products. The brand’s logo is displayed above. An identical mark was filed for registration by a Vietnamese trademark squatter. In 2023, a Vietnamese individual filed an application for registration of an identical mark (Application No. 4-2023-38668), a practice commonly observed in Vietnam as trademark squatting. The brand owner engaged Tilleke & Gibbins to assist with strategy and filing an opposition to the mark. At the time, Maurten had no trademark rights or meaningful use in Vietnam, and global marketing data showed only modest figures without any local presence. Thus, to convince the IP Office to refuse the squatter’s application, instead of relying on trademark rights or use evidence, the opposition strategy centered on the copyright protection of the logo itself, as copyright arises automatically in Vietnam upon creation of the work and does not require registration. (It is worth noting, however, that the IP Office has traditionally been cautious in accepting copyright as a basis for refusing trademark applications.) On September 24, 2024, an opposition was filed on three main grounds: confusing similarity, copyright infringement of the artistic work,

Vietnam continues to refine its intellectual property framework to align with the 2025 amendments to the Law on Intellectual Property (IP Law). On March 31, 2026, the government issued Decree 100/2026/ND-CP (Decree 100), which substantially amends Decree 65/2023/ND-CP detailing the implementation of the IP Law (Decree 65). On the same day, the Ministry of Science and Technology released Circular 10/2026/TT-BKHCN (Circular 10), providing detailed procedural guidance and new forms. Both instruments took effect on April 1, 2026, along with the amended IP Law. While the updates touch on every IP right, trademark owners and brand strategists will find several practical and forward-looking changes that directly affect filing strategy, examination timelines, portfolio management, and enforcement readiness. 1. Fast-Track Substantive Examination for Eligible Applications One of the most business-friendly innovations is the new fast-track substantive examination pathway for applications meeting specified eligibility criteria. Successful fast-track applications enjoy a shortened substantive examination period of three months. This offers a significant competitive edge for tech-driven or regulated-sector brands. If the mark is identical or similar to a mark in another person’s trademark application with an earlier filing date in the case of a priority application that has not yet been processed, the fast-track process will return to the ordinary process. However, the law does not touch on cases where marks under fast-track examination face office action due to other reasons (i.e. lack of distinctiveness, confusingly similar to others’ copyright, trade name, industrial design, etc.) 2. AI-Generated Trademarks Receive Clear Protection Pathway Decree 100 explicitly addresses the use of artificial intelligence (AI) in IP creation, amending Article 10a of Decree 65 to confirm that trademarks created with AI systems are fully protectable, provided they meet the standard requirements of registration. Trademarks face no additional “human authorship” hurdle (unlike patents or industrial designs). Brand owners

Vietnam’s most recent amendment of the Law on Intellectual Property (amended IP Law), passed by the National Assembly on December 10, 2025, and effective from April 1, 2026, represents one of the most significant updates to the IP Law in recent years. This amendment modernizes the IP framework, moving a step closer to international standards, while addressing the realities of Vietnam’s booming digital economy, e-commerce growth, and increasing foreign investment, which is crucial for Vietnam’s objective of complete economic transformation. For trademark practitioners, brand owners, and businesses, the changes are largely positive, as they promise faster processes, stronger enforcement tools—especially for online actions—and better commercialization options. However, they also introduce stricter requirements and a need for proactive preparation. Below are some of the most noteworthy changes in the amended IP Law related to trademarks. Significantly Shortened Timelines and Introduction of Fast-Track Examination The statutory timelines under the amended IP Law have been notably reduced: Substantive examination for trademarks is shortened from 9 months to 5 months (from the publication date). The publication period is shortened from 2 months to 1 month. A new fast-track mechanism allows substantive examination in as little as 3 months for qualifying applications (e.g., marks in actual use, facing infringement threats, or meeting government-specified criteria; details to be clarified in implementing regulations). The opposition period is shortened from 5 months to 3 months from publication. This is arguably the most welcome change. Vietnam’s IP Office has long faced criticism for lengthy backlogs, often stretching the trademark registration process to 18–24 months or more. The new timelines bring Vietnam closer to efficient systems. The fast-track option is particularly smart for high-value or urgent cases such as counterfeit threats on e-commerce platforms. However, careful preparation is mandatory for flawless applications from the start to maximize fast-track eligibility.
