Trademark in Vietnam: Tips for Avoiding Refusal and Protecting Your Brand

Introduction

Entering the Vietnamese market offers significant opportunities, but it also comes with legal risks – particularly in relation to intellectual property. One of the most common and costly mistakes businesses make is underestimating the complexity of trademark protection. A rejected trademark application not only delays market entry but can also force costly rebranding or even expose a business to infringement claims.

Vietnam’s trademark system has evolved rapidly in recent years, especially following amendments to the Law on Intellectual Property in 2022. While the framework is increasingly aligned with international standards, the examination practice remains strict and, in some respects, more conservative than in other jurisdictions.

Understanding how refusals arise – and more importantly, how to avoid or overcome them—is essential for protecting your brand effectively. This article provides a comprehensive, practical guide based on current regulations and real-world practice in Vietnam.

Trademark Protection System in Vietnam

Vietnam follows a first-to-file principle, meaning that trademark rights are generally granted to the party that files first, regardless of prior use (except in limited cases such as well-known trademarks). This makes early filing critically important, especially for foreign businesses entering the market.

The authority responsible for administering trademark protection is the Vietnam National Office of Intellectual Property. It examines applications, issues protection titles, and handles oppositions and invalidation proceedings.

Vietnam is also a member of key international treaties, including the Paris Convention and the Madrid System, administered by the World Intellectual Property Organization. This allows foreign applicants to seek protection in Vietnam either through national filing or international registration.

Despite this international alignment, local examination practices remain highly detailed and cautious, particularly when assessing similarity and distinctiveness. This is where many applicants encounter difficulties.

Examination Process and Timeline

The trademark examination process in Vietnam consists of several stages, each designed to ensure that the applied mark complies with legal requirements and does not conflict with existing rights.

After filing, the application undergoes a formality examination to verify compliance with procedural requirements. If accepted, it is published in the Industrial Property Gazette, allowing third parties to oppose the application.

The most critical stage is the substantive examination, where the Vietnam National Office of Intellectual Property evaluates the trademark’s eligibility for protection. This includes assessing whether the mark is distinctive and whether it conflicts with prior rights.

Although the statutory timeline is often cited as 13 to 18 months, in practice, the process can take longer. Delays are common due to the increasing volume of applications and the complexity of examinations.

Several Types of Trademark Refusals and Ways to Overcome Them in Vietnam

Trademark refusals in Vietnam are generally divided into two main categories: absolute grounds and relative grounds. Each category reflects a different set of legal concerns and requires a different strategy to overcome.

Trademark Refusal Issued on Absolute Grounds

Absolute grounds relate to the inherent characteristics of the trademark itself, regardless of other existing rights.

A common example involves marks that are identical or confusingly similar to national symbols. Vietnam strictly prohibits the registration of any sign that resembles the national flag, emblem, or other state insignia. Even indirect similarities can lead to refusal if they create a perception of official endorsement.

Similarly, marks that resemble the name or image of national leaders or historical figures may be rejected. This reflects broader public policy considerations and respect for national identity.

Another category includes marks that conflict with certification marks. If a proposed trademark is similar to a certification mark used to indicate quality or origin, it may be refused to prevent consumer confusion.

Misleading or deceptive signs are also prohibited. For example, a trademark that suggests a product originates from a particular country or has certain qualities that it does not actually possess is likely to be rejected.

One of the most frequent grounds for refusal is the lack of distinctiveness. Marks that are descriptive, generic, or commonly used in the relevant industry are considered incapable of distinguishing goods or services. This is a major issue for foreign applicants who attempt to register descriptive English terms in Vietnam.

Finally, marks that incorporate copyrighted works without authorization may also be refused. This includes logos or images derived from protected artistic works.

Trademark Refusal Issued on Relative Grounds

Relative grounds focus on conflicts between the applied trademark and existing rights held by others.

The most common issue is conflict with registered trademarks or earlier applications. Even if a mark is not identical, it may still be refused if it is considered confusingly similar in terms of visual appearance, pronunciation, or meaning.

Conflicts may also arise with widely used and recognized trademarks, even if they are not formally registered. Vietnam recognizes certain unregistered rights where sufficient evidence of use and reputation exists.

Well-known trademarks receive an even higher level of protection. If a mark is deemed well-known, it can block later applications across a broad range of goods and services, even beyond its original scope.

Trade names are another potential source of conflict. If a trademark is similar to an existing business name used in commerce, it may be refused to prevent confusion.

Geographical indications are also protected under Vietnamese law. A trademark that includes or resembles a protected geographical indication may be rejected if it misleads consumers about the origin of the goods.

Other less common but still relevant grounds include conflicts with industrial designs, plant variety names, and even copyrighted characters or images. These reflect Vietnam’s integrated approach to intellectual property protection.

Practical Measures to Overcome Refusal

While refusals can be frustrating, they are not necessarily final. Vietnamese law provides several mechanisms for applicants to respond and potentially overcome objections.

Responding to Office Actions

When the Vietnam National Office of Intellectual Property issues a refusal, it typically provides a written notification outlining the reasons. Applicants are given a deadline (usually 2–3 months, extendable) to respond.

A timely and well-prepared response is critical. Failure to respond will result in the application being deemed withdrawn.

Submitting Arguments and Evidence

One of the most effective ways to overcome refusal is by presenting legal arguments and supporting evidence. For example, an applicant may argue that the mark is sufficiently distinctive or that the differences between the applied mark and cited marks are significant enough to avoid confusion.

Evidence of use can also be helpful, particularly in demonstrating acquired distinctiveness. This may include sales data, marketing materials, and consumer recognition.

Filing a Letter of Consent (LOC)

In cases involving conflicts with earlier trademarks, obtaining a Letter of Consent from the owner of the cited mark can be a practical solution. While not always decisive, such letters can carry significant weight in the examination process.

Dividing or Amending the Application

Applicants may also choose to amend their application by narrowing the list of goods or services. This can help eliminate conflicts and allow at least part of the application to proceed.

Another option is to divide the application into separate filings. This is particularly useful when only certain classes or goods are affected by refusal.

What EU SMEs Should Do to Avoid or Overcome a Trademark Refusal in Vietnam?

For European small and medium-sized enterprises, entering the Vietnamese market often involves navigating unfamiliar legal terrain. One of the most effective strategies is to conduct a comprehensive trademark search before filing. This helps identify potential conflicts and allows businesses to adjust their branding strategy early on.

It is also advisable to avoid overly descriptive or generic marks, as these are unlikely to be accepted. Instead, businesses should focus on creating distinctive and unique brand elements that are easier to protect.

Engaging a qualified local IP agent is another key step. Local expertise is invaluable in understanding examination practices, drafting applications, and responding to office actions effectively.

Finally, businesses should adopt a proactive approach to intellectual property management. This includes monitoring the market for potential infringements and maintaining timely renewals of registered trademarks.

FAQs

How Can a Trademark Search Help Avoid Refusal in Vietnam?

A trademark search is one of the most important preventive measures in the registration process. By identifying existing trademarks that are identical or similar, applicants can assess the likelihood of refusal before filing.

In Vietnam, where the examination process is particularly strict regarding similarity, a thorough search can reveal risks that may not be immediately obvious. This allows businesses to modify their trademark, adjust their strategy, or prepare arguments in advance. Ultimately, investing in a proper search can save significant time and cost by reducing the likelihood of objections from the Vietnam National Office of Intellectual Property.

Can Using a Logo Instead of a Word Mark Reduce Refusal Risks?

In some cases, using a logo instead of a purely word-based trademark can reduce the risk of refusal, particularly when the word element is descriptive or commonly used. A stylized logo with distinctive visual elements may be considered more unique and therefore easier to protect.

However, this strategy is not without limitations. If the word element remains dominant and similar to existing trademarks, the application may still face objections. Moreover, protection for a logo is generally limited to its specific design, which may reduce flexibility in future use.

A balanced approach—combining distinctive wording with unique visual design—is often the most effective strategy.

What Mistakes Do Foreign Applicants Commonly Make When Filing in Vietnam?

Foreign applicants frequently underestimate the strictness of Vietnam’s examination process. One common mistake is choosing trademarks that are too descriptive or closely resemble existing marks. Another is failing to conduct a proper trademark search before filing.

In addition, many applicants incorrectly classify goods and services or use descriptions that do not align with local practice. This can lead to delays or partial refusals.

Another frequent issue is the lack of timely response to office actions. Missing deadlines or submitting weak arguments can result in the loss of rights. Working with experienced local representatives can help avoid these pitfalls and improve the chances of successful registration.

How Should Goods and Services Be Properly Classified to Avoid Refusal?

Proper classification of goods and services is essential for a successful trademark application in Vietnam. While the country follows the Nice Classification system, the interpretation of terms can be stricter than in other jurisdictions.

Applicants should ensure that their descriptions are clear, specific, and aligned with the actual use of the trademark. Overly broad or vague descriptions may be rejected or require amendment. At the same time, overly narrow descriptions may limit the scope of protection.

A well-prepared classification strategy not only reduces the risk of refusal but also ensures that the trademark provides meaningful protection in practice.

Conclusion

Trademark refusal in Vietnam is not uncommon, but it is often avoidable with the right preparation and strategy. By understanding the legal framework, conducting thorough searches, and responding effectively to objections, businesses can significantly improve their chances of securing protection.

In a fast-growing and increasingly competitive market like Vietnam, a well-protected trademark is more than just a legal asset—it is a cornerstone of long-term business success.
