Thai Court Finds Acquired Trademark Distinctiveness through Use in Rare Decision

World Trademark Review

Distinctiveness is a fundamental requirement for a trademark’s registration and protection under Thai law. The Thai courts typically assess distinctiveness based on a mark’s inherent characteristics rather than its use, as proving acquired distinctiveness through use requires substantial evidence, including the duration of use, extent of distribution and promotional efforts.

However, the Intellectual Property and International Trade Court (IP & IT Court) has recently ruled that the figurative mark WEPLAY had acquired distinctiveness through use – an uncommon ruling under Thai trademark law. Subsequently, the Court of Appeal for Specialised Cases affirmed the mark’s inherent distinctiveness based on a holistic assessment of its components.

This article discusses the criteria for proving both inherent and acquired distinctiveness, offering examples from both courts to provide valuable insights into case preparation and understanding of how the courts assess distinctiveness.

Background

In 2017 the plaintiff filed a trademark application for the mark depicted below for goods in Class 28, including toy building blocks:

The registrar rejected the application on the grounds of non-distinctiveness under Section 7 of the Trademark Act. The plaintiff appealed to the Board of Trademarks, which considered that, when the term ‘weplay’ is used for goods in Class 28, it is descriptive of the nature of the goods applied for as “playthings”. Therefore, ‘weplay’ was deemed nondistinctive under Section 7, Paragraph 2(2) of the Trademark Act.

IP & IT Court decision

In 2024 the IP & IT Court ruled that the term ‘weplay’ is not a coined or invented word; instead, it is a combination of ‘we’ and ‘play’, conveying the meaning of ‘we play’. When the term is used for goods in Class 28, it describes the nature of the goods as “playthings”. Consequently, the mark was deemed non-distinctive.

However, the court considered the evidence presented by the plaintiff, which showed that the latter had been selling the product in Thailand for over 10 years. This evidence, including invoices, online and print catalogue advertisements, as well as other documentation, confirmed the continuous use of the trademark alongside widespread product distribution and advertising in Thailand for over 10 years. This evidence conclusively established that goods bearing the mark had been extensively sold, distributed and advertised; therefore, the mark had acquired distinctiveness through continuous use under Section 7, Paragraph 3 of the Act. The IP & IT Court, as the court of first instance, thus adjudicated that the mark was registrable.

Both parties appealed.

Appeal decision

On 26 February 2025 the Court of Appeal for Specialised Cases held that the mark at issue consisted of two key elements:

  1. the word ‘weplay’; and
  2. a rounded-shaped device with an unusual combination of colours.

The term ‘weplay’ was found to be suggestive rather than descriptive, requiring a consumer’s interpretation to associate it with the goods. When combined with the graphic element, the mark as a whole was distinctive, enabling consumers to identify and

differentiate the goods. Accordingly, the trademark meets the distinctiveness criteria under Section 7, Paragraph 1, and Section 7, Paragraph 2(8) of the act.

The appellate court thus concluded that the mark was inherently distinctive.

Comment

The case highlights the adoption by the Thai courts of a holistic approach, contributing to a more dynamic framework for assessing trademark distinctiveness. It also shows a growing tendency to consider acquired distinctiveness through use, making it a more flexible factor in trademark litigation.

As modern business strategies increasingly embrace sustainability, the influence of ESG principles is reshaping product design, packaging, and brand protection. From label-free bottles to the legal importance of 3D marks in Thailand, these developments highlight the growing connection between environmental responsibility and intellectual property. The Rise of ESG ESG principles have become critical in shaping business strategies worldwide. Companies are increasingly required to disclose ESG data, which influences investor decisions, loans, and consumer behavior. Studies show that consumers are willing to pay more for sustainable packaging, and businesses with strong ESG commitments often achieve higher growth rates. Product Minimization Trend One sector experiencing significant transformation is the consumer product industry, where brands worldwide are adapting their packaging to align with ESG principles. A notable approach is packaging minimization, exemplified by Pepsi’s introduction of its first label-free PET bottle in China in 2022. Similarly, in Thailand, several bottled water brands have embraced label-free designs, including Sprinkle drinking water’s “Redesign to Reduce” initiative and other similar efforts. These shifts not only enhance brand perception but are also warmly welcomed by consumers and business associates alike. For instance, Cathay Pacific has introduced label-free bottled water on select flights and cabins as part of their ongoing commitment to boosting onboard recycling efforts. From Design to Distinctiveness with 3D Marks Packaging has evolved into a critical component of brand identity, blending functionality with distinctiveness to strengthen consumer recognition and loyalty. This shift carries significant implications for intellectual property. Protecting these designs is no longer optional but essential, given their substantial commercial value. Securing legal protection—whether through design rights or three-dimensional (3D) trademarks—has become a strategic necessity. In an era shaped by sustainability and innovation, safeguarding distinctive packaging is not just a precaution but a fundamental step in maintaining competitive advantage and ensuring enduring brand

In a decisive move to strengthen its trade position and reinforce commitments under ongoing tariff negotiations with the United States, the government of Vietnam has made a concerted effort to improve intellectual property enforcement within the country. A key catalyst for this was the prime minister issuing a decision requesting all authorities to initiate sweeping enforcement actions to crack down on counterfeit goods across all provinces. Our firm has been actively involved in these operations. Working in close coordination with Vietnam’s Market Surveillance Authority, Customs, and Border Police, the firm has been instrumental in planning, intelligence gathering, and on-site enforcement. Key operations were conducted in major commercial hubs, including Hanoi and Ho Chi Minh City. In Hanoi, we collaborated with Market Surveillance Team No. 1 to inspect a major wholesaler in Hang Giay. These inspections resulted in the seizure of a significant volume of counterfeit perfumes and the identification of key suppliers within the illegal trade network. In Ho Chi Minh City, our firm supported large-scale inspection campaigns at well-known markets, including Saigon Square. Acting on intelligence, authorities executed multiple raids targeting shops and stalls notorious for selling counterfeit branded products. Specialists from our firm provided logistical support and real-time analysis to ensure swift and effective intervention. Beyond Vietnam’s urban centers, efforts extended to critical border zones in northern and central Vietnam. We worked with Customs and Border Police at major checkpoints to inspect high-risk shipments suspected of containing counterfeit goods. These operations led to the interception of several container loads of illicit products. The nationwide campaign also included targeted actions in several provinces known as hubs for storage and distribution. In Bac Giang, Da Nang, Hai Phong, Kien Giang, and Dong Nai, we assisted in coordinated raids on medium- to large-scale warehouses and distribution centers. These inspections uncovered

On January 9, 2025, the Lao official gazette published the newly amended Decision on Trade Inspection Implementation No. 0019/MOIC, dated January 6, 2025. This decision aims to establish principles and rules for trade officers to inspect, fine, and take measures against violators of trade laws and their related regulations on business competition, business operations, and intellectual property rights to protect consumers and business operators in Laos. Changes in Trade Inspection Procedures Previously, trade inspection officers, operating independently under the central Ministry of Industry and Commerce (MOIC) or the provincial-level Department of Industry and Commerce (DOIC), were responsible for administrative raid actions focusing exclusively on intellectual property issues. However, following the enactment of Decision No. 0019/MOIC, trade inspection officers will now be grouped into the Trade Officers Unit, which will also include business competition officers and consumer protection officers. This unit will conduct and participate in raids, considering not only intellectual property laws but also competition and consumer protection laws when imposing penalties on infringers. Trade Inspection Authority Levels Trade inspection implementation is overseen by authorities at three levels: Central level: Department of Business Competition and Trade Inspection, MOIC. The MOIC handles trade inspection work covering all provinces in Laos. Provincial level: DOIC offices in provinces and Vientiane handle trade inspections covering two or more districts. District level: Office of the Industry and Commerce offices in districts. Violations Individuals, legal entities, and organizations violating the newly amended trade inspection decision, the Decree on Trade Inspection, or other related regulations will be educated about the issue, warned, disciplined (for government servants), fined, subject to compensation for damage incurred, or punished by the relevant laws, depending on the gravity of the violation. Trade Violations Violations of trade laws and regulations concerning business operations will result in fines and additional measures. Examples include:

The growth of Vietnam’s vibrant digital economy offers tremendous potential but is also a driver of the persistent problem of online intellectual property (IP) infringement. The spectrum of issues faced by IP rights holders runs from copyright piracy on digital services (such as streaming and torrent sites) to the sale of counterfeit goods via e-commerce sites and social platforms to the misuse of rights through misleading use of trademarks. These infringements do not only eat into profits; they damage brand reputation and mislead consumers. As a result, site blocking and keyword blocking have become increasingly important components of the enforcement toolkit available in Vietnam. Legal Framework for Blocking Actions Site and keyword blocking in Vietnam is supported by a growing legal framework, particularly following the 2022 amendment to the IP Law. Prior to this, the legal basis for blocking was scattered across various laws, and internet service providers (ISPs) were only obligated to block access to infringing content upon official requests from authorities. The introduction of Article 198b under the amended IP Law marked a significant shift, establishing a clearer mechanism for rights holders to request site blocking directly. This provision obliges them to act upon valid takedown or blocking requests. In addition to the IP Law, other key legislation includes the Law on Information Technology, the Law on Cybersecurity, the Law on Advertising, and various decrees. Together, these laws provide a more structured and enforceable basis for blocking actions in Vietnam, though practical enforcement still depends on ISP cooperation and the clarity of the infringement evidence. Competent Authorities Previously, rights holders could pursue administrative actions through specialized inspectorates under the Ministry of Science and Technology, the Ministry of Culture, Sports and Tourism, or the Vietnam E-Commerce and Digital Economy Agency (iDEA). However, due to a recent government restructuring,
