Lao Department of Intellectual Property Issues Country’s First Trademark Cancellation Decision

World Trademark Review

In decisions dated 29 September 2022, the Lao Department of Intellectual Property (DIP) has cancelled two trademark registrations based on their confusing similarity to earlier marks. An official from the DIP unofficially confirmed that these decisions are the first of their kind in Laos and, as such, constitute a positive step that puts legal provisions into actual practice.

Background

In Laos, cancellation proceedings against a registered mark are not common, as the number of applications in the country is relatively low and thorough substantive examination only began to be carried out in recent years. There was previously no precedent for how cancellation decisions would be handled, despite the Law on Intellectual Property (No. 38/NA of 15 November 2017) allowing a third party to file a petition for the cancellation of a registered mark if it can be proven that the mark should not be granted registration.

The Law on Intellectual Property states that a third party may object to, or request the cancellation of, a trademark registration within five years of its date of publication in the Official Gazette. However, it is difficult to ascertain how to calculate the five-year period if the mark was registered before June 2019, as publication in the Official Gazette was first made available at that time. This could mean that the five-year statutory limitation for trademark cancellation in Laos could start from June 2024, but how this will be applied in practice remains to be seen.

The Case

This case began when Siam Kubota Corporation Co Ltd took action against two marks that looked similar to its own earlier marks (see Figure 1):

Figure 1. Earlier registered marks

Siam Kubota registered its marks in 2009 for goods in Class 12, and has extensively used and protected the marks in Laos.

After reviewing its options, Siam Kubota submitted petitions for the cancellation of the registration of the two similar-looking marks (see Figure 2), which were also registered for goods in Class 12.

As Siam Kubota has a reputation as a longstanding, well-known seller of tractors throughout the Southeast Asian market, it was suggested that the applicant for the similar-looking marks was trying to associate itself with and imitate Siam Kubota’s marks because the parties’ marks shared essential elements. Additionally, because the products sold under these marks are marketed to consumers who use or purchase tractors, there was a substantial risk and a high likelihood of confusion in the marketplace as to the ownership and source of the goods.

In support of the cancellation petitions, Siam Kubota submitted evidence of actual use to prove that the applicant was acting in bad faith in an attempt to free-ride on the reputation of Siam Kubota’s marks. It also submitted proof of use related to sales, advertisement and promotion of goods for the DIP’s consideration.

Based on the overall representation, design and pronunciation of the marks, as well as the goods they were applied to, the DIP determined that the parties’ marks were confusingly similar. As these similarities were likely to cause confusion among the public, the DIP cancelled the contested registrations.

Comment

As the first of their kind in Laos, these decisions constitute a significant development in cancellation proceedings in the country, and will hopefully build momentum for other types of adversarial proceedings, such as oppositions. More broadly, however, these decisions mark the alignment of the law and practice in this area, which should lead to more effective protection of trademark rights.

Vietnam’s new E-Commerce Law, which took effect on 1 July 2026 along with its implementing Decree No. 248/2026/ND-CP (Decree 248), marks a significant development in the country’s approach to online intellectual property (IP) enforcement, reflecting a clear shift from a reactive model of intermediary liability to one that expects platforms to play a more active role in preventing infringement. From notice-and-takedown to platform responsibility The most significant change introduced by the E-Commerce Law is the transformation of the legal role of e-commerce platforms. The existing safe harbor provisions under the IP Law and the copyright notice-and-takedown regime established by Decree 17/2023/ND-CP (Decree 17) largely required intermediaries to act only after receiving notice of infringement. Once infringing content had been removed, the platform’s legal obligation was generally considered fulfilled. The new legislation adopts a fundamentally different approach. Article 17 of the E-Commerce Law requires intermediary platforms to screen information relating to goods and services before publication in order to prevent listings involving counterfeit or IP-infringing goods, and goods of unknown origin. Rather than relying exclusively on complaints from rights holders, platforms are now expected to implement preventive measures before infringing listings become publicly available. Decree 248 further requires platforms to update keyword filters based on recommendations issued by competent authorities. These filtering mechanisms are intended to prevent prohibited listings from appearing on the platform and represent a further move away from a purely complaint-driven enforcement model. The legislation also introduces Vietnam’s first statutory stay-down obligation. Under the E-Commerce Law and Decree 248, major digital platforms must maintain automated systems capable of reviewing, warning against, and removing unlawful listings while also implementing measures to prevent repeat violations, defined under Decree 248 as conduct that has previously been identified and handled by the platform, but continues to recur. This obligation addresses one

In March 2025, Thailand’s Central Intellectual Property and International Trade Court (IP&IT Court) issued a landmark judgment in favor of Luckin Coffee, China’s leading retail coffee chain. The judgment marked a significant turnaround following earlier trademark litigation involving Luckin Coffee from 2021 to 2023 that had generated widespread public attention and raised questions about the protection available to legitimate foreign brand owners in Thailand. In a significant subsequent development, Thailand’s Court of Appeal for Specialized Cases has now affirmed the IP&IT Court’s judgment in its entirety. The appellate decision brings clarity to one of Thailand’s most closely watched trademark disputes. Significantly, this is the first case in Thailand to formally recognize the trademark squatting principle. The Court of Appeal confirmed that Luckin Coffee has a better right to the disputed mark and ordered cancellation of the defendants’ trademark registration—a key application of the “better right” doctrine. The court also upheld the substantial damages awarded at first instance, providing important guidance on assessing harm from systematic trademark squatting. Award-Winning Judgment Affirmed in Its Entirety The significance of the first-instance judgment extended beyond the outcome for Luckin Coffee. The IP&IT Court judgment was subsequently recognized in the IP&IT Court’s Distinguished Judgment Awards in 2025, reflecting the complexity, novelty, and legal significance of the issues considered in the case. The defendants nevertheless appealed the judgment, challenging several key aspects of the IP&IT Court’s decision. Luckin Coffee continued to entrust Tilleke & Gibbins as their sole attorney to pursue the case at the appellate level. After considering the defendants’ appeal and Luckin Coffee’s submissions in response, the Court of Appeal affirmed the first-instance judgment in its entirety. The judgment was announced on July 8, 2026. Better Right to the Marks The Court of Appeal confirmed Luckin Coffee’s superior rights. The orders include cancellation

As food innovation continues to accelerate, manufacturers are increasingly introducing ingredients derived from new sources, produced using novel technologies, or lacking a significant history of human consumption. While these innovations create new opportunities for the food industry, they also raise important questions regarding consumer safety. For this reason, many jurisdictions, including Thailand, the European Union, Australia and New Zealand, Canada, and Singapore, require a premarket safety assessment for novel food ingredients before they can be placed on the market. The objective of this assessment is to ensure that each ingredient is safe for its intended use and level of consumption, does not present toxicological, allergenic, microbiological, or nutritional concerns, and will not mislead consumers. Scientific authorities typically evaluate the ingredient’s identity, manufacturing process, composition, specifications, anticipated dietary exposure, toxicological information, nutritional impact, and history of use before determining whether it can be marketed. Against this background, the Thai Food and Drug Administration (FDA) recently took an important step toward improving regulatory transparency by publishing, for the first time, a consolidated public list of substances that have successfully completed the Thai FDA’s safety assessment process, including substances determined to be novel foods and those determined not to fall within the novel food category. The list identifies the approved substances, the corresponding manufacturers or importers, approval dates, and the approved conditions of use. Although the publication does not change the existing legal framework governing novel food approvals, it provides businesses with greater visibility into the Thai FDA’s regulatory precedents and the types of substances that have previously been accepted through the safety assessment process. The full announcement is available on the Thai FDA’s website. As the list is now publicly available, it also provides useful insight into the types of substances that have successfully completed the Thai FDA’s safety assessment process.
