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.

Following the recent enactment of a comprehensive legal framework addressing sexual harassment, Thailand has launched a fast-track judicial process enabling victims of online sexual harassment to obtain court orders suspending and removing obscene content from the internet. On January 26, 2026, the Office of the Judiciary introduced the “Take It Down” procedure through the Court Integral Online Service (CIOS) platform, providing victims with their first direct, expedited pathway to halt the spread of online content that violates the new legal provisions against sexual harassment. This new remedy stems from section 284/4 of the Penal Code, introduced through the Act Amending the Penal Code (No. 30) B.E. 2568, which took effect on December 30, 2025. Under section 284/4, an injured person or a competent official may petition the court to suspend dissemination of violating data and remove the data from computer systems within a court-specified period. The court may also direct system controllers, service providers, or competent authorities to carry out the order and report back within 15 days. Filing through the CIOS Platform The CIOS platform serves as the primary electronic channel for these petitions. Key features include: Individuals can file online without appearing in person and may submit petitions at any time the system is available. Users must complete digital identity verification via the ThaID application to access the CIOS. Petitions under section 284/4 are limited to requests to suspend or remove violating content. Claims for monetary damages must be pursued separately, including via separate proceedings or prefiling mediation. Streamlined Review Process The submission workflow is end-to-end electronic, and the system provides step-by-step guidance. After submission, court staff review the petition before presenting it to a judge for consideration. The court may conduct an online inquiry to obtain additional information, and in-person attendance is required only if deemed

Arbitrations seated in Thailand are governed principally by the Arbitration Act B.E. 2545 (2002) and, where applicable, the rules of institutions such as the Thailand Arbitration Center (THAC) and the Thai Arbitration Institute (TAI). While these instruments set the core procedural structure, they are not comprehensive. To fill in these procedural gaps, arbitral tribunals often look to the Thai Civil Procedure Code (CPC) and apply its principles when the Arbitration Act or institutional rules are silent. This hybrid system is familiar to local practitioners but can surprise international parties who expect a more self-contained arbitral procedure. Examples of How CPC Principles Are Applied Evidence Management: Section 25 of the Arbitration Act requires equal treatment of the parties and guarantees each side a full opportunity to present its case. At the same time, it grants tribunals broad discretion to conduct proceedings “as it deems appropriate” and expressly suggests that arbitrators may apply the CPC evidence rules where appropriate. In practice, tribunals frequently apply CPC evidence rules when addressing: submission of evidence lists, late or additional evidence, questions of admissibility and relevance, and assessment of witness and expert testimony. Amendments to Pleadings: Because the Arbitration Act and institutional rules provide limited guidance on amending pleadings, tribunals often rely on CPC principles when parties seek to amend a statement of claim or defense. Amendments may be permitted if they are sought in a timely manner, do not unfairly prejudice the opposing party, do not cause undue delay, and do not alter the nature of the dispute. These conditions closely mirror the standards applied by Thai courts under the CPC. Subpoenas and Court Assistance: Arbitral tribunals seated in Thailand generally do not have inherent subpoena powers. Section 33 of the Arbitration Act fills this gap by permitting the tribunal, an individual arbitrator, or a

Employers operating in Thailand can enforce post-employment noncompete covenants, but success depends on precise drafting and strong evidentiary support. Thai courts will uphold restraints that protect legitimate employer interests and are fair and reasonable in duration, geographic reach, and substantive scope. Overbroad covenants, however, draw judicial skepticism and may fail unless they are drafted in severable, defensible components tied to the employee’s actual role. This article synthesizes recent trends in Thai case practice, explains how Thai courts assess reasonableness in employment restraints, and provides a practical litigation-focused framework for drafting enforceable covenants, preparing evidence, and pursuing relief through the Labor Court. The Legal Framework and Its Practical Implications Thai courts evaluate noncompete covenants under general principles of contract enforceability and public policy, with particular focus on whether a restraint is necessary to protect a legitimate employer interest and proportionate to that objective. In employment matters, this analysis is shaped by the employee-protective tenor of Thai labor law and by the Labor Court’s equitable discretion in determining appropriate remedies. The practical takeaway is that standardized or broadly drafted covenants rarely survive scrutiny. Courts look for a demonstrable nexus between the employee’s actual exposure to confidential information, trade secrets, or customer relationships and the scope of the restraint. Where that nexus is weak or the restraint operates as a blanket prohibition, courts are inclined to decline enforcement or limit relief to a narrowly tailored prohibition. The employer interests most commonly recognized as legitimate in Thai practice include the protection of trade secrets, confidential business information, and goodwill tied to identifiable customer segments or territories. Courts are more likely to enforce restraints where employers can clearly document what information is at risk, why particular customer relationships matter, and how the employee was involved with those assets. Judges also look closely at the

Doing business in Thailand means operating under a strict regulatory framework. From time to time, companies may receive unexpected administrative orders from government authorities that restrict their operations, impose new compliance obligations, or levy fines and penalties. When this happens, a business may challenge the order under Thailand’s administrative law system. The primary concern in pursuing administrative litigation is timing, as strict statutory deadlines apply and missing them can permanently affect a company’s rights. First Step: Administrative Appeal Many companies assume the first step is to immediately bring the matter before the Administrative Court to seek revocation or suspension of the order. Some even attempt to request an interim injunction to stop the order from taking effect. However, Thai law generally requires that the company first challenge the order through an administrative appeal with the same agency that issued it. Only after this process is complete can the matter be taken to court. Seeking an interim injunction at this stage is also not possible. This is because Thai law does not allow a standalone application for an interim injunction; an injunction can only be requested together with the underlying complaint filed with the Administrative Court. Since a court complaint cannot be filed until the administrative appeal process has been exhausted, an injunction is usually not available at the early stage. What Are the Timeframes for Administrative Appeal? Thailand applies a two-stage administrative appeal process. The appeal must first be submitted to the same authority that issued the order, which will review its own decision. If that authority affirms its decision, the appeal is then escalated to the relevant higher authority for further review. In most cases, both stages must be completed before a company is allowed to proceed to court. The timeframe for filing an administrative appeal is very
