Trademark License Agreements in Thailand: Choice-of-Law Clauses and Registration Requirements

Informed Counsel

In order to receive royalties, a trademark owner may license out its trademark rights to another party. To license trademark rights, a trademark license agreement must be made in writing and registered at the Department of Intellectual Property (DIP), in accordance with Section 68 of the Thai Trademark Act. If a trademark license agreement is not registered, it will be void, according to Section 152 of the Civil and Commercial Code and the support of various Supreme Court judgments (Decisions 7770/2547, 6436/2543, and 6190/2550). Registration helps disclose the owner and origin of the goods to avoid confusion among the public.

Sometimes the parties to a trademark license agreement will include a choice-of-law clause in the agreement, designating a foreign governing law. This raises a key question: if a choice-of-law clause indicates that a trademark license agreement is governed by foreign law, does it still need to be registered as required under Thai law? The Central Bankruptcy Court recently answered this question in a case involving the largest amount of compensation ever requested in the history of the courts for breach of a trademark license agreement.

Tilleke & Gibbins’ client, a leading manufacturer and supplier of customized fittings and pipes, is a trademark owner in various countries, including Thailand. A former director of our client assigned its trademark to another party, the opposing party in this case. At a later point, the opposing party granted a license to our client, which became the licensee of the trademark. The former director and the opposing party included a choice-of-law clause in the agreement designating English law as the governing law. The parties did not register the license agreement with the DIP.

At a later point, our client underwent reorganization, during which it was alleged that our client had failed to perform its obligations under the trademark license agreement. The opposing party subsequently filed a request for compensation arising out of a breach of the license agreement for THB 6.9 billion, the largest amount of compensation ever requested in the history of the courts for breach of a trademark license agreement.

Among other defenses, our client argued that the trademark license agreement was void under Section 152 of the Civil and Commercial Code, because it was not registered at the DIP in accordance with Section 68 of the Trademark Act. In rebuttal, the opposing party claimed that the choice-of-law clause in the agreement designating English law as the governing law meant that registration under Thai law was not required.

In Thailand, a trademark license agreement is based on the general legal principle of freedom of contract. The parties to a trademark license agreement may essentially agree on any term in the agreement as long as it is not prohibited by law.

In this case, the parties chose a foreign law to govern the trademark license agreement to avoid having to comply with requirements under Thai law. Generally, a dispute regarding a trademark license agreement falls within the jurisdiction of the Intellectual Property and International Trade Court. However, as the dispute in this case was raised while our client was undergoing reorganization, jurisdiction fell within the purview of the Central Bankruptcy Court.

The Central Bankruptcy Court decided that the trademark license agreement was required to be registered in Thailand because the trademarks were registered and protected under Thai law. Because the trademark license agreement was not registered in Thailand, the agreement was void, in accordance with Section 68 of the Trademark Act and Section 152 of the Civil and Commercial Code. Therefore, the opposing party had no right to claim THB 6.9 billion in compensation.

Notably, the Central Bankruptcy Court did not state that the choice-of-law clause was invalid. Instead, the Court clarified that the choice-of-law clause did not serve as an exception to Section 68. Regardless of the choice-of-law clause, the trademark license agreement was still required to be registered with the DIP. Licensors and licensees should be aware of this ruling and ensure that their trademark license agreements are registered in Thailand.

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.
