Important Supreme Court Decision on Suggestive Marks

Informed Counsel

The recent amendments to Thailand’s Trademark Act No. 3 B.E. 2559 (2016) introduce a number of significant changes. No changes, however, were made to the requirement of distinctiveness in Section 7, paragraph 2, which states: “a trademark having, or consisting of, a word or clause that has no direct reference to the character or quality of the goods, and is not a geographical name as prescribed by the Minister in the Ministerial Notifications (among others), shall be deemed distinctive.”

Brand owners often create marks that directly or indirectly describe their products or services. In Thailand, registrars usually interpret the requirement of descriptiveness strictly, and they have broad discretion in determining the translations of marks and whether certain portions of marks must be disclaimed. In addition, as the Board of Trademarks rarely disagrees with the registrar on these issues, disputes have frequently arisen between brand owners and the Trademark Office over the rejection of suggestive marks for descriptiveness.

In general, a suggestive mark is different from a descriptive mark because in the case of a suggestive mark, a consumer has to use some imagination or creative thinking to determine what kinds of goods or services are being offered under the mark, as opposed to a descriptive mark, where these goods or services are readily apparent from the mark itself.

A decision on distinctiveness was recently issued by the Supreme Court under Supreme Court Case 2587/2559, TMB Bank Public Company Limited v. the Department of Intellectual Property. In this case, the plaintiff filed a trademark application to register the mark “TMB Make THE Difference” ( ) for banking services in Class 36.

After reviewing the application, the registrar agreed to accept the mark for registration on the condition that the plaintiff must disclaim the exclusive right to the words, “Make THE Difference,” because these words are descriptive. The plaintiff did not agree with the registrar’s disclaimer requirement and decided to file an appeal to the Board of Trademarks.

The Board of Trademarks confirmed the registrar’s decision that the words must be disclaimed on the basis that they are descriptive. The Board also found that the evidence submitted by the plaintiff was not sufficient to prove that the plaintiff had widely and continuously used the words “Make THE Difference” to the point where they had gained a secondary meaning.

The plaintiff then filed a complaint to the Intellectual Property and International Trade Court (IP&IT Court), contending that the Board of Trademarks’ decision on the disclaimer was incorrect because “Make THE Difference” is an unusual combination of the three individual words, and together, they are not directly descriptive of the character or quality of the services.

The IP&IT Court agreed with the registrar’s and the Board of Trademarks’ assessments and ordered the plaintiff’s case to be dismissed. The plaintiff then filed an appeal with the Supreme Court. The Supreme Court took a different view toward the issue and considered the meaning of the words in the context of the plaintiff’s services.

The Supreme Court found that “Make THE Difference” is not a phrase common to other trade words published by the Trademark Office and that these words, together, are not directly descriptive of commercial banking services. The Supreme Court, therefore, ultimately concluded that the mark “TMB Make THE Difference” is registrable and the plaintiff was not required to disclaim the exclusive right to the words “Make THE Difference.” The Board of Trademarks’ decision had to be withdrawn.

It is striking that the Supreme Court appears to have a more nuanced approach in making determinations based on the descriptiveness of a mark. In this decision, the Supreme Court appears to be clearly distinguishing between suggestive marks and descriptive marks. If the reasoning that underlies this decision is subsequently followed by the registrar and the Board of Trademarks, this decision should have a lasting impact on the registrability of suggestive marks 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’s cabinet has approved two draft amendments aimed at improving labor-related judicial proceedings. The proposed amendments to the Act on the Establishment of Labor Courts and Labor Case Procedure B.E. 2522 (1979) and the Act on Procedures for Human Trafficking Cases B.E. 2559 (2016) are intended to make the process more efficient, appropriate, and fair. Key elements of these proposed amendments are outlined below. Expansion of Labor Court Jurisdiction Under the current framework, labor courts generally hear labor disputes, while criminal offenses under labor laws are handled separately. Matters involving both labor and criminal issues may therefore require the parties to pursue proceedings before different courts. To address this, the proposed amendments would expand the jurisdiction of labor courts to cover certain criminal offenses under labor laws. The government states that the change is intended to allow related issues to be heard by judges with expertise in labor law and to reduce the need for parallel proceedings. The proposed amendments also set out the following rules for cases involving multiple offenses. Where a single act gives rise to multiple offenses and at least one of those offenses falls within the jurisdiction of the labor court, the labor court may hear the related offenses as part of the same case. Where multiple connected acts give rise to different offenses, the labor court may hear the matters together or transfer part of the case to the appropriate court, taking into account convenience and the interests of justice. Criminal Offenses Covered The proposed amendments would extend labor court jurisdiction to criminal offenses under 11 labor-related laws, including laws concerning: Home workers protection Labor protection Labor protection in fisheries work Employment and job-seeker protection Management of foreign workers Social security Occupational safety, health, and working environment Compensation Maritime labor State enterprise labor relations

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
