Well-Known Marks in Vietnam: Legal Framework and Practical Obstacles

Informed Counsel

In 1992, the National Office of Intellectual Property of Vietnam (NOIP) refused a trademark application due to its confusing similarity to the unregistered, but well-known, McDONALD’S trademark of the U.S. fast-food chain. This refusal was based merely on the reputation of the mark, as McDonald’s—at the time—had not yet used or shown any intention to use such mark in Vietnam. This was the very first case involving a “well-known mark” in Vietnam.

Legal Framework

At the time of the McDonald’s case, the term “well-known mark” was not officially defined in any Vietnamese legal document. There existed only Decree 197-HDBT, dated December 14, 1982, of the Council of Ministers on Regulation of Trademarks, which provided: “signs that are identical or similar to marks that are previously registered in Vietnam or protected under international treaties to which Vietnam is a member for the same goods are not accepted as trademarks.”

Later, “well-known mark” was indirectly mentioned in Article 6.1e of Decree 63/CP, dated October 24, 1996, stating that, as one of the criteria for protection, a sign shall not be “identical or confusingly similar to others’ well-known trademarks (in accordance with Article 6 bis Paris Convention) or to others’ trademarks that are widely used and recognized.” Subsequently, Decree 06/2001/ND-CP, dated February 1, 2001, defined a well-known mark as “a mark that is used continuously for goods/services of good reputation, leading to the mark becoming widely known.”

Since the McDonald’s case, the legal framework for well-known marks has evolved from a Decree (a legal normative document issued by the Government) into the Intellectual Property Law issued in 2005 and amended in 2009. Under the prevailing IP Law, a well-known mark is defined in Article 4 as “a mark widely known by consumers throughout the Vietnamese territory,” with further criteria provided in Article 75.

Practical Obstacles

Despite the evolution of the legal framework, the number of marks recognized as well-known in Vietnam has not increased significantly (based on the estimates of some IP agents through their practice, as no official statistics are kept). Several factors may have contributed to this lack of growth.

First, the NOIP seems to be becoming stricter in recognizing well-known marks. Some marks that are well-known, even famous, worldwide are not recognized as well known by the NOIP, due to the lack of intensive and long-term use in Vietnam. In light of Item 2 of Article 75, the NOIP now requires intensive evidence showing the use of a mark within the territory of Vietnam for the purpose of recognizing a well-known mark. “Spill-over” effect, together with use of the mark in foreign and neighboring countries, is insufficient to prove the well-known status of the mark in Vietnam. The NOIP also imposes a higher requirement of formality on the evidence, such as requiring that the evidence be an original or certified copy and properly dated.

Second, as defined in Article 4, a mark is considered to be well known if it is known by consumers throughout the Vietnamese territory. By this definition, it seems that Vietnam requires that a well-known mark should be known by the public at large, not only by a pool of relevant and potential consumers.

Recently, some worldwide well-known marks have only been recognized by the NOIP as widely used, or as well known in Vietnam for certain goods and services, but not well known by the public at large. Obviously, no mark (not even the most well-known mark) will be used for all kinds of goods or services, especially marks for niche goods or professional services such as industrial machinery or financial services.

The practice that a mark may be recognized as well known for certain goods or services but not for others carries a potentially significant risk that such a mark may not be protected against the use of identical or confusingly similar marks for different goods or services. This runs contrary to the international practice, in which the scope of protection of a well-known mark often extends beyond the exact goods or services for which the well-known mark is used, and it is also inconsistent with Article 74.2(i) of Vietnam’s IP Law, which prevents the registration of a sign that is identical or confusingly similar to a well-known mark even for dissimilar goods or services, as follows: “if the use of such mark may affect the distinctiveness of the well-known mark or the mark registration is aimed at taking advantage of the reputation of the well-known mark.”

Along with the overly strict review process, inefficiencies in the system could be discouraging trademark owners from even attempting to get their well-known marks recognized in Vietnam. For example, the IP Law requires that a List of Well-Known Marks should be kept and maintained by the NOIP. In practice, however, there has never been such a list. Thus, the owner of a well-known mark must prove that its mark is well known in Vietnam over and over again in every single case. As the process of recognizing a well-known mark requires intensive evidence, it takes a significant amount of time and effort for the trademark owner to collect the evidence (which must be updated from time to time) and for the NOIP to study and assess the evidence for every single case.

Seeking Consistency

While it is up to Vietnam to decide how high the standards should be for determining well-known marks, the NOIP should be consistent in its rulings and adhere to the relevant international practices. As a first step, more transparency is required. Specifically, the NOIP and other competent authorities should publish their decisions on recognizing (and not recognizing) well-known marks. This may help to increase consistency in their rulings and build public awareness of well-known marks.

Laos has significantly broadened its industrial property administrative review framework, most notably by extending it to cover copyright and related rights for the first time. Decision No. 0306/IC on the Administrative Resolution of Disputes Concerning Industrial Property Registration, New Plant Variety Registration, and Copyright and Related Rights Recordation took effect on April 24, 2026, replacing the previous rules from 2023, which had covered only industrial property and new plant variety matters. Decision No. 0306/IC governs how Laos’ Department of Intellectual Property (DIP) and provincial offices handle formal challenges to industrial property registrations and applications. The proceedings covered include oppositions to pending applications, appeals of refused applications, requests for cancellation of existing registrations, and—newly—disputes concerning the recordation and interpretation of copyright and related rights. These administrative proceedings within the DIP are heard by a government-appointed Administrative Dispute Resolution Committee, which functions similarly to the opposition and review boards found in other jurisdictions. Key Changes Decision No. 0306/IC covers four categories of administrative proceedings: Oppositions: Third-party challenges to a pending industrial property application before it is granted. Refusal appeals: Challenges to the DIP’s decision to refuse their application. Cancellation or deletion requests: Applications to invalidate an existing registered right on the grounds that it should not have been granted. Copyright and related rights disputes: Challenges to or interpretations of copyright and related rights recordations, including determinations of whether a work qualifies for copyright protection under Lao law. The most significant development is the committee’s new jurisdiction over copyright matters. The committee is now empowered to resolve disputes concerning copyright and related rights recordation—this includes the authority to determine whether a work qualifies for copyright protection and to interpret the scope of an existing recordation.

Vietnam’s Decree No. 134/2026/ND‑CP, which took effect on 9 April 2026, plays an important role in detailing and implementing Vietnam’s Intellectual Property (IP) Law in the context of rapid digital transformation and the growing application of artificial intelligence (AI). The new decree provides comprehensive guidance on the application of copyright and related‑rights regulations, addressing key issues such as authorship, ownership, statutory exceptions and limitations, registration procedures, and enforcement mechanisms. Through these measures, Decree 134 seeks to achieve an appropriate balance between safeguarding the legitimate interests of rightsholders and fostering innovation, research, and technological advancement, thereby strengthening the state’s framework for the effective management, protection, and exploitation of intellectual property in the digital and AI‑driven environment. Some notable aspects of Decree 134 are discussed below. Copyright for AI-Created Works Decree 134 provides important guidance on the determination of copyright and related rights in works created with the assistance of AI. Article 5a reaffirms the principle that human creativity remains central to copyright protection, clarifying that copyright or related rights arise only where a human makes a substantial and decisive intellectual contribution, exercises effective control over the creative outcome, and assumes responsibility for the content and its legality. At the same time, the provision confirms that AI is regarded solely as a technological tool rather than a rights‑holding subject, thus ensuring consistency with the fundamental concepts of authorship and ownership under the IP Law. By introducing requirements on transparency, proof of human contribution, and compliance with AI‑specific labelling and technical marking obligations, Decree 134 establishes a clear and enforceable legal framework for the responsible use of AI in creative activities. Lawful Use of Copyrighted Texts and Data Article 37a of Decree 134 sets out the specific conditions under which copyrighted texts and data may be lawfully used for scientific research, experimentation,

Across the region, local brands have become key drivers of economic growth, cultural identity, and innovation, and Myanmar is no exception. From traditional products and creative industries to modern startups and small and medium‑sized enterprises (SMEs), Myanmar’s local brands are increasingly shaping domestic markets. However, as local brands grow, they also face higher risks of imitation, misuse, and unfair competition. In this context, protecting brand identity, creativity, and innovation through proper intellectual property (IP) strategies is essential to ensure that Myanmar’s homegrown businesses can grow sustainably, compete confidently, and retain the value of what they create. The Key IP Laws for Local Brands In 2019, Myanmar enacted a comprehensive suite of four IP laws, aligning the nation’s IP enforcement framework with international standards. Trademark Law 2019: This law introduced the “first-to-file” system into the country, with trademark rights primarily obtained through registration with the Intellectual Property Department (IPD). Trademarks protect brand names, logos, and other signs that distinguish goods or services. Registration grants the exclusive rights to use the mark and to prevent others from using identical or confusingly similar marks. Each registration lasts for 10 years from the filing date and can be renewed for subsequent 10-year periods. Copyright Law 2019: Copyright, which arises automatically upon creation, protects literary, artistic, musical, and audiovisual works, including software, advertisements, artwork, and social media content. While registration with the IPD is not mandatory under this law, it can be helpful for establishing evidence and supporting any future enforcement. The terms of protection for economic rights associated with copyrights vary depending on the type of work involved. In contrast, the protection for moral rights lasts indefinitely—continuing even after the author’s death. Industrial Design Law 2019: Under this law, any industrial design that is new and independently created can be filed with the
