Supreme Court Decision Clarifies Trademark License Registration Requirements

Informed Counsel

Similar to the trademark licensing practice in several countries, a trademark license agreement in Thailand must be registered with the Registrar at the Department of Intellectual Property (DIP). If two parties make an agreement but fail to register it, the licensing parties do not have the right to enforce the license agreement. Thus, the registration of a trademark license agreement is essential in Thailand.

However, because the Trademark Act does not define the term “trademark license,” the question often arises as to which types of agreements are considered to be trademark licenses that need to be registered. In other words, practitioners often ask whether agreements such as distributorship agreements, franchising agreements, or technology transfer agreements—each of which may have an element of trademark use—need to be registered with the DIP. A recent Supreme Court case has provided at least a partial response to this question.

Requirements Under the Thai Trademark Act

According to Section 68 of the Trademark Act B.E. 2534 (1991), the owner of a registered trademark may grant a license to other persons for any, or all, of the goods for which it is registered. However, such trademark license agreement must be registered with the DIP. Applications for registration of a trademark license agreement must be in accordance with the rules and procedures of Ministerial Regulation No. 1, which prescribes the required documents and lays out the process for filing applications.

Under current Thai law, a trademark license agreement must be undertaken in writing, and must at least identify:

  1. The conditions and terms of the agreement between a trademark proprietor and a person applying to be an authorized licensee, which enables the former to control the quality of the goods or services;
  2. The goods or services for which the licensed trademark is to be used; and
  3. A provision specifying that only an authorized licensee has the right to use the trademark, or that such proprietor shall authorize any person, in addition to the authorized licensee, to use it.

Failure to comply with the contract formality requirements would render the licensing agreement invalid.

Supreme Court Decision

A 2010 Supreme Court decision, Bangchak Petroleum Public Company Limited v. Sanpatong SR Petroleum Limited Partnership et al. (Dika case 10207/2553), has shed new light on the types of agreements to which these formality requirements apply.

Bangchak Petroleum, the plaintiff in this case, owned the registered mark BANGCHAK in Thailand, for use with petroleum fuel and petroleum products. Bangchak granted the rights to Sanpatong SR Petroleum and its managing partner, the defendants in this case, to operate a retail outlet, in the form of a gas station, to sell gasoline and petroleum products. Bangchak remained the proprietor of the land, building, all the construction located in the outlet, and all the equipment used to operate the gas station.

The defendants missed a payment for the delivered products, as well as a royalty fee, insurance premium, penalties for late payment, and damages for selling petroleum products from other sources in the gas station, amongst other requirements.

As a result, Bangchak filed a case with the Intellectual Property and International Trade Court (IP&IT Court) to claim for damages totaling approximately THB 10 million (or approximately USD 330,000). The plaintiff also demanded that the defendants be removed from the properties and that such properties be returned to the plaintiff.

Sanpatong and its managing partner argued that the agreement they made with Bangchak was not enforceable because the license agreement at dispute was not registered with the DIP. In its decision, the IP&IT Court awarded debt receivable to Bangchak but held that the agreement between the parties, which contained a clause allowing the defendants to use the plaintiff ’s trademark, was invalid because the parties had failed to properly register the license agreement with the DIP.

Bangchak appealed to the Supreme Court, arguing that the agreement at dispute was not meant to be a trademark license agreement, as it merely granted Sanpatong the right to operate a retail unit (i.e., a gas station), while Bangchak was the proprietor of the land, construction, equipment, signboard, and trademark used within the gas station.

The Supreme Court agreed with Bangchak’s argument and reversed the IP&IT Court’s decision on the issue of trademark license agreement. The Court ruled that even if there was an element of use of the mark BANGCHAK with the products, the mark was in fact used by its owner. The defendants bought products from the plaintiff, and then sold such goods to the public. This was not a case in which the defendants sought to obtain their own supply source, and then used the plaintiff ’s trademark with the supplied products, with the plaintiff ’s authorization. Therefore, the agreement in this case was not a trademark license agreement that must be formally registered.

Analysis

Interpreting the Supreme Court’s decision in this case, it appears that if two parties have a transaction wherein one party only acts as a middleman to distribute or sell the other party’s products to consumers, such a transaction is not considered to be use of a trademark. Thus, it can be interpreted that a straightforward distributorship agreement should not be considered to be a trademark license agreement, and therefore is not required to be registered with the DIP.

Based on the specific facts of this case, it is worth noting that the plaintiff provided most of the equipment and property to the defendants, in order to operate the gas station. Furthermore, the defendants were not likely to have control of the marketing activities, nor did they produce any advertisements using or mentioning the plaintiff’s trademark, since these activities were undertaken by the trademark owner.

In this context, this Supreme Court decision provides important guidance on the circumstances under which an agreement needs to be registered, and it may prove helpful in settling some aspects of this long-running registration debate.

Indonesia’s regulation on reporting online intellectual property (IP) infringement provides comprehensive procedural guidance for IP rights holders and their licensees in reporting online infringement complaints. Issued in December 2025 by the Ministry of Law as Regulation No. 47 of 2025 regarding Handling of Intellectual Property Infringement Reports in Electronic Systems, this regulation covers all types of IP rights. It also specifies documentation when reporting infringement, and lays out the procedures for examination, verification, and enforcement actions. Submission of Complaints Complainants may submit reports through the online system of the Directorate General of Intellectual Property (DGIP) or in person at the DGIP office. Complaints may also be filed through an authorized proxy. Under the regulation, complainants are required to provide the following information and documents: Personal details of the complainant; Brief description of the protected work or subject matter (i.e., type of IP and name or address of the infringing website, portal, account, or application, or a link to the location of the infringing content); Complete description of the alleged infringement; Certificate of registration or recordal of the relevant IP; Recordal of IP license agreement, if any; and Other supporting evidence. Verification and Examination Process Upon receiving a complaint, the responsible formality officer may request clarification or additional supporting documents. In the latter case, the complainant must then submit the necessary administrative documents within 14 days of the notification date. Once the documentation is deemed complete and sufficient, the case will be formally registered. Subsequently, the DGIP will establish a verification team to handle online IP violations, which will include the Civil Servant Investigator (PPNS), the Ministry of Communication and Digital Affairs, experts with relevant expertise in IP, and representatives from related associations such as AVISI (Indonesian Video Streaming Association). After examining the report, the team will prepare the Minutes

Customs recordation is an enforcement mechanism in Myanmar that enables intellectual property (IP) rights holders to seek prevention of the cross-border movement of infringing goods. The enactment of Myanmar’s IP laws in 2019 has enabled customs recordation for registered marks and copyrights under the Trademark Law 2019 and the Copyright Law 2019. By contrast, the Patent Law 2019 and the Industrial Design Law 2019 do not provide a practical framework for customs recordation, and accordingly such rights are not subject to the customs recordation regime. Under the Trademark Law 2019, rights holders may apply for customs recordation and may also ask the Customs Department to suspend the release of goods suspected of bearing counterfeit marks. Likewise, the Copyright Law 2019 allows for customs intervention in relation to pirated works. These provisions reflect Myanmar’s gradual alignment with international standards on border measures, although the implementation framework remains at a relatively early stage of development. Customs Recordation Pursuant to the Trademark Law 2019 and the Copyright Law 2019, the relevant authorities have issued customs rules concerning the protection of registered marks and copyrights. In practice, the process generally begins with the submission of an application to the Customs Department together with supporting documentation. This typically includes proof of registration in Myanmar; details of the rights holder, applicant, and any authorized representative; and a comprehensive description of the genuine goods. Product identification materials—such as photographs, packaging samples, and distinguishing features—are particularly important in helping customs officers identify suspected infringing goods. A recordation remains valid for two years from the date of approval. It may be renewed for additional two-year terms, provided that the renewal application is filed within the thirty days prior to expiry for marks and up to thirty days in advance of the expiry date for copyrights, in accordance with

Thailand’s cabinet has approved the draft Act on Liability for Defective Goods, commonly called Thailand’s “Lemon Law.” The Draft Act is currently pending consideration by Parliament. The draft law aims to strengthen buyers’ position in pursuing cases against sellers. While the Civil and Commercial Code offers provisions governing liability for defective goods, it is difficult in practice for buyers to successfully make a claim against sellers, particularly where defects are latent and not discoverable at the time of sale or delivery. By introducing product-specific rules and clearer remedies, the new law is intended to modernize Thailand’s consumer protection framework and align it more closely with international standards, and to help relieve the buyer’s burden of proof against the seller in product liability cases. If enacted, the draft act will take effect 180 days after publication in the Government Gazette, giving businesses a transition period to assess their compliance obligations. This article provides an overview of the key provisions of the draft act and highlights some practical considerations for businesses operating in Thailand. Scope and Key Definitions The draft act applies to sellers—defined as persons who sell goods in the ordinary course of business—and protects buyers, a term defined broadly to include not just the original purchaser but also transferees and successors in title. This expands the class of people who can bring claims. The law does not apply to used goods, live animals, or goods exempted by future ministerial regulation. It also leaves intact any separate warranties, promises, advertisements, or other guarantees a seller has given; those remain enforceable alongside the new statutory rights. General Liability for Defective Goods Sellers are liable for defects that exist at the time of delivery, regardless of whether the seller knew about them. Liability arises where a defect reduces: The benefit intended under

Patent enablement requirements are provided under Article 102 of Vietnam’s Law on Intellectual Property (IP Law). In particular, a patent specification must “fully and clearly disclose the nature of the invention to such an extent that, based on the specification, a person having ordinary skill in the relevant art can implement the invention.” In pharmaceutical and biotechnology patents, this requirement is more complicated and subject to more rigorous assessment. The Patent Examination Guidelines (Guidelines) of the Intellectual Property Office of Vietnam (IP Office) were amended in March 2026 to introduce Annexes III and IV for the pharmaceutical and biotechnology sectors, in which Annex III provides detailed guidelines on the assessment of specification requirements. These amendments were made under a project for strengthening capacity in industrial property examination between the Japan International Cooperation Agency (JICA) and the IP Office. Annex III provides detailed instructions on how examiners assess enablement in a pharmaceutical or biotechnology application, and offers examples of acceptable and unacceptable descriptions with regard to the enablement aspect. Enablement Requirements in Pharma and Biotech Patents Article 12.7 of Circular 10/2026/TT-BKHCN (Circular 10) adds to the requirements of Article 102 of the IP Law that the description must demonstrate the novelty, inventive step, and industrial applicability of the technical solution. For pharmaceutical composition subject matters, Article 12.9 of Circular 10 sets out that the description must present the results of clinical trials and/or the pharmacological effects of the claimed pharmaceutical composition, and must include at least the following information: Substance/mixture used. Testing method (system) employed. Information on the test results. Correlation between the pharmacological effects obtained from the tests and the application of the pharmaceutical product in the prevention, diagnosis, and treatment of diseases. The Guidelines note that pharmacological study results should be presented in a quantified manner, and pharmacological
