Multiple-Class Trademark Applications: Understanding Thailand’s New Procedures

Informed Counsel

Multiple-class trademark applications became available in Thailand for the first time by virtue of the Thailand Trademark Act (No. 3) B.E. 2559, which amended the Thailand Trademark Act B.E. 2534, and which came into effect on July 28, 2016. The amended Trademark Act allows you, as a trademark owner, to file one application to cover goods and/or services in more than one international class. This provides an important new option, but there are still circumstances in which you may prefer to file separate single-class trademark applications. This article will provide an overview of your options under both approaches.

In the past, if you wanted to register one trademark in many classes in Thailand, you were required to file separate single-class applications for each class. Under the new law, you can simply file one multiple-class application for all the intended classes at once.

A multiple-class application may be administratively more efficient than separate single-class applications, because your multiple-class application will have one application number and registration number, and one application and registration date. You will therefore have less administrative work when maintaining your multiple-class applications. Similarly, if you need to change your name or address, or assign the application/registration to another party, only one filing will be necessary, rather than separate filings for each classification. Thus, a multiple-class application can be an attractive option.

But there are also drawbacks to filing a multiple-class application in Thailand. One drawback is that you may face delays in obtaining registration in certain circumstances. For example, in the event that the Thai Trademark Registrar issues a notification relating to one or more classes covered by your application, the entire application will be delayed until the matters raised in the notification are resolved. Currently, it is not possible to divide a multiple-class application after filing. Thus, there is a risk that all classes will be delayed if one or more classes encounter a problem. Under the existing practice, your only available option to move the application forward is to delete the problematic class(es) from the application.

When seeking trademark registration, you will naturally be concerned about the costs of the process. The government fees for filing, registration, and renewal of both single- and multiple-class trademark applications are based on the number of items of goods/services in each classification. This means that the government fee will not differ if you choose to file a multiple-class application rather than a single-class application.

Therefore, as explained above, the main benefit of the new system allowing for the filing of multiple-class applications is improved efficiency in the application, registration, and renewal of a mark that is filed in more than one class. However, there may be drawbacks to multiple-class applications during the application phase.

The availability of multiple-class applications in Thailand is a positive development and will certainly be welcomed by trademark owners and practitioners as another option within the trademark system. When applying for a new mark, your decision about whether to file a single- or multiple-class trademark application will depend on several variables, such as whether you need the registration to be issued speedily, the chances that your application will encounter problems in some classes, and your own preferences with respect to administration of your marks. In certain circumstances, you may decide to file separate single-class applications to ensure that your specific objectives can be achieved.

In Thailand, the rise in online intellectual property infringement has prompted authorities to strengthen enforcement efforts, including the use of website-blocking orders under Section 20(3) of the Computer Crime Act B.E. 2560 (2017) (CCA). This provision authorizes the Ministry of Digital Economy and Society (MDES), with court approval, to block or remove computer data that constitutes a criminal offence under IP law. Since its implementation, the procedure has undergone several developments, which is an encouraging sign of progress. Website-blocking procedure In practice, website-blocking orders under Section 20(3) of the CCA are primarily used for copyright and trademark infringement. While such orders are legally applicable to patent infringement, their use remains challenging due to the difficulty of proving infringement through administrative procedures. The website-blocking procedure begins when an IP owner identifies online infringing content. For copyright infringement, which is considered a compoundable offence, the IP owner is required to first file a police report with the specialized police unit known as the Economic Crime Suppression Division (ECD) prior to filing the website-blocking application with the Department of Intellectual Property (DIP). For trademark infringement cases, the application can be filed directly with the DIP without a prior police report. The DIP reviews the evidence and, if infringement is confirmed, forwards it to the MDES for further consideration. If the case is deemed valid, the MDES requests a court order to block the infringing website. Once granted, the MDES notifies the internet service providers (ISPs) to block access to the specified website. Website blocking procedure in Thailand Recent advancements in website-blocking actions Seamless collaboration through digital integration. Thailand has made significant progress in digitizing its website-blocking procedures to improve efficiency and transparency. At present, all website-blocking applications and supporting evidence must be submitted in electronic format. These systems have significantly reduced processing

Online shopping in Thailand is more accessible than ever, with global platforms, local social media shops, and entertainment-driven social commerce enabling instant purchases. However, this convenience comes with rising concerns over digital intellectual property (IP) infringement, including counterfeit goods, pirated content, and unauthorized brand usage. At first glance, online platforms appear to offer quick solutions. Most major e-commerce sites, social media channels, and social commerce platforms provide “notice and takedown” systems, where IP owners can file complaints and request the removal of listings that infringe IP rights, such as trademarks and copyrights. These tools are certainly useful, as seeing a fake product vanish from a platform feels like progress. But the reality is less reassuring. The counterfeit goods themselves remain in warehouses, markets, or shops, ready to be resold. Sellers whose accounts are taken down often return within days under new names or accounts. In other words, a takedown is like cutting weeds without pulling out the roots: they always grow back. While notice and takedown tools are widely available and can be managed internally by most IP owners, their impact is often short-lived. IP owners seeking more effective, lasting protection need to take a more strategic and multilayered approach. The same applies to online piracy. Unauthorized streaming websites that offer free access to movies, TV shows, or sports broadcasts have become widespread in Thailand. To combat this, rightsholders can request website blocking under the Computer Crime Act, through the Ministry of Digital Economy and Society and the courts. Once requests are approved, internet service providers are ordered to block access to infringing sites. Blocking orders can be effective in disrupting large-scale piracy operations, but they also face limitations—pirate sites frequently reappear under new domains. Strategic Protection Whether the infringing material is physical counterfeit goods or intangible streaming content,

On June 6, 2025, the Superior People’s Court in Hanoi overturned a non-use cancellation decision by the Intellectual Property Office of Vietnam, a rare and impactful occurrence. In a ruling that may help clarify the enforcement of Vietnam’s IP Law, the court held that valid trademark use can be established through commercial arrangements where the brand owner maintains actual control over the use of the mark, and is not confined to relationships governed by a so-called “formal license agreement. Background: Cross-Border Use, Local Challenge A Singapore company owns a well-known brand of consumer products that has gained recognition across Southeast Asia. In recent years, the brand has been targeted by several unauthorized trademark filings in Vietnam. In one such instance, a local Vietnamese trading company—previously linked to the production and export of counterfeit goods to neighboring countries—filed a non-use cancellation against the Singapore company’s mark and sought to register it under its own name. If the cancellation had been upheld, it would have enabled a complete hijacking of the brand. The IP holder operates in Vietnam through a structured cross-border supply chain. Under an agreement between two related foreign entities, one of which managed regional operations, production orders were placed through a designated Vietnamese company. While the Vietnamese manufacturer was not a party to the agreement, its role in using the mark was recognized and governed by internal and commercial documentation. The Vietnamese manufacturer lawfully obtained the necessary permits, regulatory approvals, and customs clearances for producing the goods in Vietnam. These activities were supported by banking records and internal communications, evidencing active, continuous use of the mark in Vietnam. However, the IP Office concluded that this use did not meet the statutory criteria because the Vietnamese manufacturer did not have a direct license agreement with the brand owner, as

Indonesia’s current regulations on franchises, as stipulated under Government Regulation No. 35/2024 on Franchising and its implementing regulation, Ministry of Trade (MOT) Regulation No. 71/2019 regarding Implementation of Franchising, highlight fundamental changes in franchise registration. These changes have introduced additional complexities and challenges in the franchise registration procedure, making it more difficult for franchise owners to navigate the process. New procedure Franchise applications are still submitted through the Online Single Submission (OSS) portal of the Capital Investment Coordinating Board (BKPM). However, the new procedure requires each applicant, including foreign franchisors, to have an OSS account and a business registration number (NIB) issued by BKPM. An application for franchise registration must be submitted under the applicant’s own account—submissions can no longer be made through the account of a consultant. Once a franchise application is submitted, the authority will distribute the submission to the MOT—the authorized ministry for franchise registration. Any notification or decision upon the registration made by the MOT will be available in the OSS system. Applicants should regularly monitor the status of the franchise application because no notifications will be sent to applicants to alert them of any deficiency. Here is the summary of the new procedure for franchisors: Notable Requirements The disclosure document, or prospectus, is the key focus for the MOT in examining a franchise registration for a franchisor. This document is subject to thorough scrutiny by the MOT to ensure that all mandatory information meets the requirements set in the franchise regulations. The current regulations specifically require that the mandatory clause “business system” in the prospectus cover operational standards and procedures, which should include human resource management, administration, operational management, standard operating methods, business location selection, business premises design, employee requirements, and marketing strategies. Other clauses that are equally important to pay attention to are:
