Regulatory Impingement of Intellectual Property Rights in Thailand

T-AB: Thai-American Business, Journal of the American Chamber of Commerce in Thailand

There have recently been a number of troubling developments in tobacco and alcohol legislation and regulation in Thailand that encroach upon intellectual property (IP). Other highly regulated products, such as cosmetics, food products, and drugs, are also feeling a regulatory pinch. These regulations have impinged legitimately granted IP rights and to a greater extent, rights to property, to engage in competition, and to free speech.

To assess the extent of regulatory impingement of IP rights in Thailand, it is essential to analyze the current situation with respect to certain industries. Within that context, an overview of relief options is also presented.

The Current State of IP Rights Impingement in Thailand

Tobacco

Thailand already has some of the most stringent tobacco regulations in the world. For example, all packs of tobacco must include graphic health warnings that cover 85% of the exterior packaging (a requirement that was introduced in 2014), smoking is banned in most places, and the advertising of tobacco products is prohibited. Furthermore, Thailand’s Ministry of Public Health (MoPH) may adopt Australia’s recent plain packaging initiative.

In 2010, a draft Tobacco Consumption Control Act was introduced in Thailand that aimed to implement more restrictions on activities essential to any business involved in the tobacco industry, including pricing strategies, precluding extension of trademarks to non-tobacco goods and services, and deciding the design of product packaging (without the involvement of tobacco businesses or the Department of Intellectual Property (DIP)). 

Draft Article 40 of the Act provided additional restrictions on advertising and was also an instrument through which plain packaging initiatives could be introduced. Specifically, the MoPH would acquire wide-ranging powers to make decisions on packaging designs having “a size, color, symbol, label, including the character of the displaying of trademark, symbol, picture, and message, that are in compliance with the criteria as notified by the [MoPH].”

Draft Article 31, however, was particularly troubling, as it served as a far-reaching prohibition on advertising that went beyond the existing regulations. The new language sought to prohibit the use of importer’s/exporter’s names or trademarks and included a ban on all “advertising or marketing communications.”

Additionally, draft Article 32 went even further by prohibiting the display of tobacco product names or trademarks or tobacco product importer or manufacturer names or trademarks on any other products. Therefore, if a mark were to be used for tobacco products or if a trademark was registered in International Class 34, then that mark or trademark could not be used on any other product, and the sale of any such product would thus be restricted.

In August 2013, various interested parties obtained a preliminary injunction against the MoPH’s proposed Notification requiring an increase in Graphic Health Warnings on tobacco products. The injunction held for ten months before being overturned. A complaint remains at the Central Administrative Court. 

On November 24, 2014, the MoPH signed a slightly revised draft law, retitled the Tobacco Products Control Act, which was submitted to the Cabinet Secretary shortly thereafter. That draft is currently circulating around the various Ministries for comment. The new Act is largely identical to its 2010 predecessor, save for a slight addition to draft Section 37, which now contains the ominous statement, “the law on intellectual property shall not apply to the display of the Package under this Section.” 

This should make for an interesting dialogue between the Ministry of Commerce, where the DIP sits, and the MoPH.

Alcohol

In Thailand, the advertising, marketing, sale, labeling, and packaging of alcoholic beverages is governed by the Alcoholic Beverage Control Act 2008. 

In 2010, the MoPH published a draft notification requiring alcohol labels and packages to display graphic health warnings covering between 30-50% of the label or package. The World Trade Organization (WTO) Technical Barriers to Trade Committee was notified of the draft measure, and a number of countries raised objections and/or comments to the proposal.

In January 2014, the MoPH announced a draft notification prohibiting the use of various types of messages on alcoholic beverage labels and packages, including any message “which misleads consumers on the content of products,” and any message “using the picture of a cartoon.” 

In August 2014, a revised draft notification was issued—essentially a hybrid of the earlier two. 

On December 24, 2014, the MoPH signed a final version of the Notification in which the graphic health warning provisions had been deleted, but included revised versions of the labeling restrictions, including prohibitions on “a message which materially misleads consumers about the content of products” and “a message using cartoon images, except images which are trademarks of alcoholic beverages which have been legitimately registered prior to enforcement of this Notification.” Here, it should be noted that the Trademark Act does recognize unregistered marks, so again, there is an attempt by the MoPH to override existing Thai trademark law which, like international trademark law, fully recognizes unregistered trademarks.     

Unless successfully challenged, the Notification comes into force 90 days after its publication in the Government Gazette.

Other Industries

The introduction of specific regulations in the cosmetic, food products, medical devices, and pediatric nutrition industries has undermined rights associated with trademarks. For instance, words such as BIO, NANO, or 24K, which are commonly registered as trademarks, cannot be used in connection with cosmetic products and words such as “slim,” “lean,” “white,” or images depicting thinness or intelligence are prohibited on food unless it is proven that such characteristics or ingredients exist in the product formula. 

Although both the DIP and the Food and Drug Administration share the common objective to prevent consumers from being misled, the DIP focuses on whether the trademark is distinctive and identifies the source of the goods or services, whereas the Food and Drug Administration focuses on the intent behind the product name. There is currently no linkage between these two agencies, unlike in many other nations.     

Possible National Grounds for Challenging Regulatory Impingement of IP

Constitutional Issues

The 2007 Constitution protects property and grants people the liberties to engage in enterprise and to undertake fair and free competition through Section 43. The current interim constitution, adopted last year, does not contain an analogous provision covering these principles. However, according to Sections 4 and 5 of the interim constitution, these rights must be protected as long as they are not inconsistent with the interim constitution.

Sections 41 and 86 of the 2007 Constitution provides protection for individual property and intellectual property respectively. 

Thai laws and regulations that prevent the full enjoyment of trademark rights may conflict with Section 29, as it imposes the requirements of necessity and proportionality on the restrictions flowing from the impinging regulation.

Administrative Court

Encroaching legislation can be challenged locally in Thailand by filing a complaint in the Administrative Court on such grounds as:

  • the issuance of the impinging regulation amounts to an ultra vires act;
  • incompatibility with national trademark law, constitutional rights, and international treaty provisions;
  • failure to follow due process, including consultation and regulatory impact assessment; and
  • the act or rule is unnecessary and disproportionate.

Trademark Arguments – Value and a Right to Use

Trademarks provide substantial benefits to their owners in terms of asset value, licensing value, assignment value, and overall goodwill. Importantly, trademarks differentiate the goods of one business from the goods of others, thereby conferring an important valuable benefit to Thai consumers.

By registering a trademark, a trademark owner has obtained the exclusive and positive rights to use and license the use of the trademark in Thailand as per Section 44 of the Trademark Act.

As in any country, trademark owners face a risk that their trademarks may be cancelled if they are not used for a prescribed period of time (in Thailand, this is three years). Therefore, if a trademark is declared unusable on a good or service by way of a regulatory rule, then after three years of such inability to use, it can be stricken from the Trademark Registry, leaving it vulnerable to being re-registered by a bad faith third party or leaving it open to use by counterfeiters without any means of stopping this by the former owner. 

Challenging Impinging Regulations under Trade Agreements

Continued promulgation of rules and regulations that defeat IP would question Thailand’s obligations under various international treaties, including the World Trade Organization Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS). Specifically, Article 20 prohibits unjustifiable encumbrances on the use of a trademark in the course of trade.

Currently, Thailand is not a party to Trans-Pacific Partnership (TPP) negotiations. If Thailand joins this trade pact in the future, the Investor-State Dispute Settlement (ISDS) provisions, which are believed to be set out in the TPP Investment Chapter, could be invoked by IP owners who see their rights encroached upon by authorities as a means to challenge impinging regulations.

Approach

Thai authorities need to ensure that any regulatory measures introduced do not infringe upon constitutional rights, undermine IP protection, or violate international trade obligations. It will be an interesting period of time to observe whether any further regulatory encroachments will be approved by the government and, if so, what legal challenges IP owners may be able to make against these.

Indonesia’s trademark prosecution process has been significantly streamlined with Ministry of Law Regulation No. 5 of 2026 (MOLR 5/2026) coming into effect on February 23, 2026. In straightforward cases without opposition, applicants may now see their trademarks proceed to registration within three months from filing—a substantial improvement over previous practice. The regulation also introduces detailed procedures for recording changes of name and address and for transferring rights over pending applications. It enhances the role of the Ministry of Law’s regional offices in assisting local individuals and SMEs, adds provisions governing force majeure situations, implements new requirements for collective trademarks, and formalizes several practices already in place. Substantive Examination Acceleration The most significant change under MOLR 5/2026 concerns substantive examination. The regulation now explicitly requires that applications be published within 15 days of filing, followed by a two-month publication period. Oppositions must be filed only within this window; late submissions will not be processed, even if the system accepts payment. The new regulation requires the Trademark Office (TMO) to forward copies of any opposition to applicants within 14 days of receipt. If no opposition is filed, substantive examination begins immediately after the publication period ends and will be completed within 30 days. If an opposition is filed, the examination is to be finalized within 90 days of the counterstatement filing date. These timelines enable unopposed applications to move from close of publication to final decision in roughly one month. If an application is provisionally refused during ex officio examination, the applicant has 30 working days from the date of notification to file a response. However, the regulation does not specify the timeline for subsequent reexamination after the response is filed. In recent practice, the TMO has been completing reexamination within approximately two to three months. Ownership Recordals May Pause Substantive

Myanmar’s Trademark Law 2019 introduced a modern framework for the registration, enforcement, and protection of trademarks. However, due to the high volume of applications filed during the soft-opening period of the Intellectual Property Department (IPD), marks submitted from 2022 onward remain pending as the IPD works its way through the applications filed in 2021, which it has been publishing on a monthly basis since May 1, 2024. During this period, businesses should adopt proactive strategies to protect their brands, monitor conflicting marks, and ensure a smooth registration process. Practical Steps for Safeguarding Pending Marks While a pending application does not confer full trademark rights, brand owners can take several practical steps to strengthen their position: Monitor IPD publications. Businesses should regularly review the IPD’s monthly gazette to identify any identical or confusingly similar marks at an early stage and prepare timely oppositions in accordance with the Trademark Law’s provisions allowing “any interested party” to file an objection to a trademark application. Monitor market activity. Early detection of potential infringement enables swift action, such as cease-and-desist letters and opposition proceedings. Businesses should monitor competitors, distributors, and retailers for unauthorized use of their marks. Collect evidence of use. Maintaining evidence of use strengthens claims of distinctiveness and supports enforcement efforts. Businesses should keep records of commercial activities, distribution, brand promotion and development, marketing communications, product packaging and labeling, and sales demonstrating brand recognition in Myanmar and internationally, particularly in Southeast Asian markets. Although the Trademark Law 2019 establishes a first-to-file system, evidence of use provides considerable practical support for distinctiveness claims and enforcement actions. Pursue Interim Enforcement Options. A pending trademark application can be relied upon to oppose or refuse other marks on absolute and/or relative grounds of refusal. In addition, marks with established reputations may be protected under passing-off principles

On January 26, 2026, Vietnam’s Ministry of Finance issued Circular No. 06/2026/TT-BTC (Circular 06), amending and supplementing Circular No. 13/2015/TT-BTC, which provides guidance on dossiers and procedures for customs recordal and customs supervision in relation to intellectual property rights (IPR). Circular 06 has an effective date of March 1, 2026. Some notable points of Circular 06 include the following: Simplified Documentation for Customs Recordal Applications Circular 06 reduces some documentary requirements for IPR owners: A power of attorney is no longer required to be legalized. Applicants are no longer required to submit title or registration certificates if such documents are issued in digital form. In such cases, it is sufficient to declare comprehensive information on the relevant IPR, enabling customs authorities to verify the information through publicly accessible databases. In practice, this amendment is particularly beneficial for international trademark registrations designating Vietnam. IPR owners may no longer need to obtain a confirmation letter from the Intellectual Property Office of Vietnam regarding the validity of a trademark registration in Vietnam. Instead, they may rely on registration status information available from the World Intellectual Property Organization (WIPO) database, reflecting that the international registration has been granted protection in Vietnam. Clearer Mechanism for Ex Officio Suspension of Suspected Infringing Goods Although ex officio suspension has been referenced in earlier regulations, Circular 06 provides clearer guidance on the circumstances and procedures under which customs may proactively suspend customs procedures for consignments suspected of being counterfeit or pirated goods. Accordingly, customs authorities may initiate the suspension of clearance without waiting for a formal request from IPR owners. Enhanced Supervision of Imported/Exported Goods in E-Commerce Circular 06 also supplements provisions on the inspection of imported and exported goods transacted through e-commerce channels. Customs authorities may apply risk management measures to assess goods traded via e-commerce

Thailand is preparing to offer new tools for intellectual property enforcement as the Electronic Transactions Development Agency (ETDA) recently released for public consultation a draft notification requiring social media platforms to verify user identities and conduct know-your-customer (KYC) checks on advertisers. The draft Notification of the Electronic Transactions Commission on Measures to Prevent Technological Crimes for Social Media Service Providers, which is to be issued under the Emergency Decree on Measures for the Prevention and Suppression of Technological Crimes B.E. 2566 (2023), as amended in 2025, primarily aims to combat online fraud and technology-related crimes. However, its new obligations also provide IP owners with valuable tools to identify anonymous infringers. Key Regulatory Mandates The draft notification imposes several verification requirements on social media platforms operating in Thailand. These requirements also strengthen IP rights holders’ ability to identify anonymous infringers, as platforms must: Verify user identities through registered phone numbers and link all accounts to verifiable identities. Conduct KYC checks on advertisers, including individuals, companies, and any third-party payers. Perform heightened identity checks for high-risk or repeat offenders before publishing advertisements. Promptly remove content flagged by the Anti-Technology Crime Division and prescreen advertisements for prohibited or high-risk content. How IP Owners Can Use This Notification for Enforcement The phone number–based verification requirement enables IP owners to work more effectively with enforcement authorities in tracing individuals or entities responsible for infringing content. The comprehensive advertiser KYC obligations, including mandatory disclosure of third-party payment sources, create a clear audit trail even when bad actors attempt to obscure their identity through intermediaries or shell accounts. This traceability is essential for pursuing damages and dismantling organized counterfeit operations. The ETDA is now considering adjustments to the draft notification after receiving comments during the public consultation period, which ended on February 2, 2026. Following finalization
