Vietnam: Bad Faith Trademark Filings

Managing Intellectual Property

Bad faith trademark filings are not uncommon in Vietnam. In fact, bad faith is often included under the label of “dishonesty basis” as a ground for opposition or cancellation of a trademark application/registration. Generally speaking, bad faith is deemed to occur when an applicant intentionally registers a trademark to benefit from the goodwill and reputation associated with the trademark of another owner. Some notable issues of bad faith trademark filings in Vietnam are discussed below.

Criteria for Determining Bad Faith

The criteria for determining bad faith are not specified in any relevant statutory provisions. However, the notion of bad faith trademark filings is shown in court rulings as well as in decisions of competent authorities like the National Office of Intellectual Property (NOIP) and the Ministry of Science and Technology (MOST). Typical examples of bad faith trademark filings in Vietnam include:

  • An applicant files for registration of a trademark that is identical or confusingly similar to a well-known trademark with the intention of preventing the owner of such well-known trademark from entering the Vietnam market.
  • An applicant files for registration of a well-known trademark with no intention of using it, but for the sole purpose of benefiting from the sale, licensing, or transfer of the registration to the rightful owner of the well-known trademark.
  • An applicant simply wishes to profit from the reputation of a well-known trademark.

Many of the criteria for determining bad faith which are recognized as best practices in the INTA Resolution on Bad Faith are not yet recognized in Vietnam. For example, the warehousing of trademarks and related domain names, or the copying of very striking or unique logos or trade dress is often not considered bad faith.

Strategies to Address Bad Faith Applications

In Vietnam, proving the applicant’s knowledge of the pre-existence of a trademark is crucial in showing bad faith. However, in practice, proof of such prior knowledge can be very difficult to obtain if the applicant keeps denying any knowledge of the prior trademark, or the trademark applied for in bad faith is confusingly similar but not identical to the prior trademark. Therefore, the best strategy is to obtain incontestable proof showing prior knowledge, which is a document evidencing that there was once a business relationship/cooperation experience between the applicant and the rights holder, such as a contract signed between the two parties, payment vouchers, etc.

In addition to citing evidence of prior knowledge, rights holders can also focus on the lack of intent to use the mark to strengthen bad faith arguments. In other words, rights holders can prove that the applicant is requesting trademark protection for certain goods/services but, in practice, as well as in terms of long-term business strategy, the applicant does not manufacture or trade in such goods/services. This helps show that the applicant might be registering the mark just to disrupt the rights holder’s business activities, to prevent the rights holder from acquiring its trademark rights, or to sell, license, or otherwise transfer the mark to the rights holder.

Specifically, evidence showing the applicant’s lack of intent to use the mark might include:

  • Applicant’s lack of documentary or other objective evidence that it can/will use the mark;
  • Applicant’s lack of capacity or experience needed to manufacture or trade in the goods/services bearing the mark;
  • No licensing of the mark;
  • Failure to take any concrete actions or to develop any concrete plans for use;
  • Applicant’s pattern of filing for marks which were then not put into use.

Where appropriate, rights holders may also consider mentioning multiple filings by the applicant if the applicant has a history of filing for marks that are similar to other well-known trademarks.

Tips for Rights Holders

Trademark owners can take steps to discourage the practice of bad faith trademark filings:

Filing for trademark registration:  Vietnam adopts the first-to-file principle, which grants exclusive trademark rights to the first party that applies for registration of the mark. Therefore, filing for trademark registration in Vietnam as soon as possible will help rights holders prevent bad faith trademark applications from maturing to registrations. Further, the cost for registering a trademark is much lower than the cost to pursue an opposition or cancellation against a confusingly similar or identical mark applied for in bad faith.

Keeping a close watch on the IP Gazette:  After passing the formality examination, a trademark application is published in the monthly IP Gazette issued by the NOIP. Keeping a close watch on the IP Gazette will help rights holders detect any mark that might be applied for in bad faith. Rights holders could then file an opposition against such mark before it matures into registration. Once the mark has been registered, rights holders have no choice but to file for cancellation of the mark applied for in bad faith. In practice, pursuing a cancellation case is much more expensive and time-consuming than an opposition case, and the chance of success is very low.

Indonesia’s Constitutional Court (Mahkamah Konstitusi) has reinstated a key provision limiting pharmaceutical patent protection, signaling a renewed commitment to balancing patent rights with public access to medicines. In its ruling to Case No. 255/PUU-XXIII/2025, the court partially granted a petition for judicial review of Law No. 65 of 2024, which had amended the country’s Patent Law, and ordered the restoration of a provision that had excluded certain pharmaceutical inventions from patentability. The decision took effect immediately upon its pronouncement at the court’s plenary session on August 28, 2026. Background The petition challenged the removal of article 4(f) from Law No. 13 of 2016 concerning Patents (Patent Law), as amended by Law No. 65 of 2024. Article 4(f) had excluded from patentability certain inventions relating to new uses of known substances. The petitioners argued that removing this provision would open the door to patent protection for second medical use inventions and facilitate patent evergreening—practices that can extend exclusivity periods, delay generic market entry, and reduce public access to affordable medicines. The petitioners included several patient advocacy and public-interest organizations: the Indonesian Dialysis Patients Community Association, the Indonesian Association of Drug Abuse Victims (PKNI), the Indonesian Pulmonary Hypertension Foundation (YHPI), the Rekat Peduli Indonesia Foundation, and the Indonesian Positive Women’s Association (IPPI), along with the Indonesia for Global Justice Association and four individual petitioners. The petitioners also challenged the constitutionality of the phrase “interested party” in article 70(1) of the Patent Law, arguing that it should be construed expressly to clarify who has standing to appeal a decision to grant a patent before the Board of Patent Appeal, and to allow a broader range of parties—such as patent holders, licensees, consumer organizations, prosecutors, aggrieved third parties, and others who may suffer direct or indirect harm from the grant of a patent—to

Thailand and China have a longstanding and significant trade relationship, which increasingly extends to e-commerce and digitally enabled supply chains. While these channels create new opportunities for businesses to reach consumers across borders, their growth also brings greater exposure to intellectual property (IP) infringement across jurisdictions and online platforms. Effective cooperation between the two countries’ enforcement authorities has therefore become increasingly important. To strengthen cooperation in this area, Thailand and China signed a memorandum of understanding (MOU) on IP enforcement in Beijing on July 20, 2026, during the Thai prime minister’s official visit to China. Officially titled “Memorandum of Understanding Between the State Administration for Market Regulation of the People’s Republic of China and the Ministry of Commerce of the Kingdom of Thailand on Cooperation in the Field of Intellectual Property Enforcement,” the MOU forms part of a broader bilateral agenda covering industrial and supply chains, participation by micro, small, and medium-sized enterprises (MSMEs), cooperation associated with the ASEAN–China Free Trade Area 3.0, and progress on the registration of Thai geographical indications in China. The MOU establishes a bilateral framework for cooperation and coordination in five broad areas: Strengthening dialogue in IP enforcement; Enhancing information sharing; Facilitating the enforcement of IP rights in cases arising in the parties’ domestic markets and on online platforms, in accordance with their respective domestic laws; Promoting cooperation in IP enforcement training and human resource development; and Undertaking other cooperation activities agreed upon by both sides. The Department of Intellectual Property (DIP) will serve as the principal coordinating agency for Thailand, while the Bureau of Law Enforcement and Inspection in China’s State Administration for Market Regulation (SAMR) will serve in that role for China. The framework is particularly relevant to the growth of e-commerce, as it covers infringement in the domestic markets and on

When considering a franchise, many people first think of a restaurant, retail chain, or service outlet. From a legal perspective, however, the foundation of every franchise lies in the right to use a brand, which is typically granted through a trademark license. Trademarks are often the most valuable assets in a franchise system. Through a trademark license, a franchisor authorizes a franchisee to use its trademarks, logos, and branding while maintaining control over how the brand is presented to customers. The Role of Trademarks in Franchise Businesses Under the Trademark Law 2019, a mark is defined as a sign that is capable of distinguishing the goods or services of one undertaking from those of others in the course of trade. This distinguishing function is particularly important in a franchise arrangement, where the franchisee’s use of the franchisor’s trademark allows consumers to recognize the source, quality, and reputation of the business. In this way, trademarks help preserve brand identity, strengthen market recognition, and protect the commercial value of the franchise system. Legal Foundation for Franchise Brand Protection Myanmar presently does not have a specific statutory framework governing franchise arrangements. As a result, franchise agreements are generally regulated under the broader applicable legal framework, including the Contract Act 1872, the Trademark Law 2019, the Competition Law 2015, the Consumer Protection Law 2019, and the relevant implementing rules and regulations. The licensing of trademarks within a franchise arrangement is particularly governed by the Trademark Law 2019. Franchisors should ensure that the trademarks intended to be licensed to franchisees in Myanmar are registered under the Trademark Law 2019 and that the relevant trademark license is properly recorded with the Intellectual Property Department (IPD). Trademark License Recordal Under the Trademark Law 2019, the owner of a registered trademark may grant a license to another

It is generally understood that patents are granted for new designs that have not been widely known or used in Thailand and not been disclosed anywhere prior to the date of the patent application. It is trite law that design law protects the distinctive appearance or products. Under Section 3 of the Thai Patent Act B.E. 2522, as amended by the Patent Act (No. 2) B.E. 2535 and the Patent Act (No. 3) B.E. 2542, a design is defined as “any form or composition of lines or colors that gives a product a special appearance and can serve as a pattern for an industrial or handicraft product.” This raises an important question. Can a patent be issued for a product design that contains text, numerals, trademarks, or symbols that do not fall under the definition of a design? This issue commonly arises when attempting to register packaging, labels, and graphical user interfaces (GUIs). Until a few years ago, applicants could file design applications with the Thai Patent Office for designs that contained such elements, provided that an appropriate disclaimer was included. This practice was generally accepted by Thai design examiners at that time, but the Patent Office has since implemented a change in its practice that could have a significant impact on applicants for design patents. Where design representations are submitted as line drawings or computer-aided design (CAD) drawings, the examiner may now issue an office action requiring their removal. This practice, however, appears to be applied inconsistently, as some examiners still exercise their own discretion in determining whether drawings containing these elements are acceptable. Below are examples of a GUI design, a CAD drawing design, and a photographic design representation that illustrates issues relating to the presence of nonallowable elements.
