Developments in Life Sciences Trademark and Regulatory Restrictions in Thailand

Informed Counsel

Regulatory issues related to the commercialization of life sciences products cannot be overlooked or brushed aside. As a first step, an intellectual property (IP) owner needs to obtain a marketing authorization license from the relevant regulatory authorities, while exercising their best efforts to protect their IP rights.

When considering consumer protection, trademark laws and life sciences product regulation laws have similar objectives—to protect consumers from misrepresentation. Misrepresentation in the trademark sense involves misrepresenting the origin of goods, while misrepresentation in the product regulation sense involves overclaims made about a product’s properties or characteristics.

A tension exists between these two areas of the law, which is to the disadvantage of consumers and business operators alike. This article examines developments in life sciences trademark and regulatory restrictions in Thailand, where trademark and regulatory authorities do not always see eye to eye.

Trademarks

Among the various categories of trademark, suggestive word marks are the most frequent subject of regulatory objections in Thailand. Section 7, paragraphs 2 and 9 of the Trademark Act B.E. 2534 (1991), as amended, confirms the eligibility of a word or figurative mark that is “not directly descriptive of characteristics or property of the goods…” (emphasis added). The distinction between direct descriptiveness and suggestiveness has been consistently affirmed by Thai Supreme Court decisions.

According to Section 44 of the Trademark Act, the right of trademark is formulated as “the registered proprietor of the trademark shall be entitled to the exclusive right to use that trademark in respect of the goods for which it has been registered.” This is clearly a positive right to use, as opposed to the negative right to prevent others from use, as found in some other jurisdictions. The same provision provides exceptions to this right only in cases of: (1) concurrent and independent uses in good faith, or (2) trademark licensing.

Product Regulations

Laws and subsequent regulations for highly regulated life sciences products—drugs, medical devices, cosmetics, or food—usually prohibit the use of a product name that is exaggerating or misleading when considering the nature of the represented product. Misleading product names are generally understood to be those suggesting that the product belongs to another category (e.g., a food name that alludes to a type of medical therapy), or contains an ingredient that it in fact does not have. Exaggeration refers to names that convey absoluteness (e.g., “free,” “zero,” “instant cold remedy”) or unsubstantiated product claims.

It is not a mandatory requirement for a product’s trademark to be registered before that product is registered in Thailand. Thus, in most cases, the Thai Food and Drug Administration (FDA) will not require proof of trademark registration. Recently, the FDA has objected to the use of certain product names with the wording “extra white” or “slim.” In addition, a brand or trademark with the terms “doctor” or “Dr.” will not be allowed, unless the applicant can prove that the product is owned or has been designed by a named doctor, including submitting proof of qualifications. In such cases, obtaining trademark registration alone is not sufficient to convince the FDA to grant marketing authorization.

Problems can also arise when a proposed word mark contains a word element that is suggestive of a positive attribute (e.g. “max,” “super,” “life,” “vita,” and “health”). Promulgated regulations and notifications grant regulators broad discretionary powers to object to the use of a product name if they determine that it could be misleading or exaggerating. Such regulatory decisions are occasionally influenced by public sentiments, and sometimes yield unpredictable or inconsistent results, especially across the different regulatory offices involved with different product categories.

It is therefore possible to surmise that the criteria for regulatory approval are stricter and less clear than the requirements for trademark registration. In fact, a number of registered Thai trademarks have been rejected during the application process for marketing authorization, effectively restricting or delaying the right to use a successfully registered trademark.

Business Implications

Business concerns are rightfully based on Thailand’s constitutional right to trade and the state’s constitutional duty to ensure that any regulatory mechanisms do not create unnecessary obstacles to a Thai citizen’s trading capabilities.

However, a marketing authorization dispute usually takes months or even years to resolve. The damage suffered from business interruption is magnified when the subject of the pending application is part of a regional or global marketing plan, which involves setting up manufacturing sites and arranging for logistics in several locations. Collectively, this practice projects an IP-hostile climate, affecting Thailand’s competitiveness.

While recognizing regulators’ duties to safeguard consumers against commercial misrepresentation, the regulatory framework should also account for private entities’ rights to conduct business. To this end, the existing framework should be improved so that (1) IP implications and trading concerns are taken into account; (2) clear and predictable guidelines are provided; and (3) examination practices across various regulatory offices are consistently applied and based on understandable rationales.

Business operators, especially those in the life sciences sector, should be aware of the complex interactions between IP and product regulations to avoid major business impacts. Before pursuing registration, it is essential to conduct a thorough assessment from both an IP and a regulatory perspective, taking into account the feasibility of a product name, relevance of trademark registration, steps to registration and marketing approval, and suitable and effective responses to potential office actions.

On December 31, 2025, Vietnam’s Ministry of Health (MOH) issued Circular No. 57/2025/TT-BYT providing guidance on the classification of medical devices according to technical standards and quality requirements (Circular 57), applicable to procurement activities for medical devices in Vietnam. According to the MOH, the purpose of the classification is to establish a principle-based legal framework and regulations that enable purchasers to easily identify groups of medical devices aligned with their professional requirements and financial capacity. Some of the key stipulations of Circular 57 are outlined below. Basis for Determining Technical Standards and Quality Under Circular 57, the technical standards of medical devices are determined in accordance with Vietnamese laws on standards and technical regulations, through the following means: Certification of conformity with standards in accordance with Vietnamese laws on standards and technical regulations; Results of conformity assessment conducted by an internationally recognized conformity assessment organization or a legally established domestic or foreign conformity assessment organization operating in Vietnam; and Documentation evidencing compliance provided by the medical device owner. The quality of medical devices is determined based on whether the device has been approved for circulation by the relevant marketing authority of one or more jurisdictions. Classification of Medical Devices Circular 57 classifies medical devices into six groups (from Group 1 to Group 6) based on technical standards and quality. Medical devices subject to classification must simultaneously meet technical standards and quality requirements in accordance with professional specifications and user needs, and must be lawfully marketed in Vietnam. Medical devices manufactured in Vietnam may participate in all corresponding groups, provided they meet the technical standards required by the user and are lawfully marketed in Vietnam. Outlook Circular No. 57 will take effect on February 15, 2026, while the classification requirements will become effective on January 1, 2027. Holders of medical

The Intellectual Property Office of Vietnam (IP Office), with support from the Japan International Cooperation Agency (JICA), is drafting additional annexes to its Guidelines for Patent Examination, focusing on the examination of patent applications in the pharmaceutical and biotechnology sectors. The new annexes are expected to be officially issued in early 2026 as Annexes III and IV, following the successful issuance in 2023 of Annexes I and II addressing computer program-related inventions. The IP Office recently organized a seminar to gather feedback on the draft annexes from intellectual property representatives, academic institutions, research institutes, and other interested parties, emphasizing its intention to receive further constructive opinions to refine the guidelines for pharmaceuticals and biotechnology. Why These Guidelines Matter Patent examination in Vietnam has traditionally relied on the Guidelines for Patent Examination issued under Decision No. 487/QD-SHTT (2010), recently supplemented by Annexes I and II. While these documents provide a solid foundation, they do not fully address practical challenges in examining pharmaceutical and biotech inventions, particularly issues related to clarity, sufficiency of disclosure, enablement, features of function and utility, combination therapies, and inventions involving artificial intelligence (AI) applications in these fields. Annexes III and IV aim to close these gaps by introducing structured principles and illustrative examples. Guidance on Patent Specification Requirements Annex III provides detailed guidance on the requirements for patent specifications in pharmaceuticals and biotechnology, covering two main parts: Part A addresses sufficiency of disclosure, clarity of specifications, and consistency between claims and descriptions. Part B covers inventions related to Markush-type compounds, claims containing exclusion statements (disclaimers), and additional experimental data submitted during examination. The Guidelines outline specific disclosure requirements for subject matters such as compounds, formulations, pharmaceutical compositions, genes, polypeptides, proteins, vectors, transgenic organisms, modified organisms, and hybrid cells. Annex III emphasizes that disclaimers are not accepted
