Ambush marketing refers to a strategy in which a business associates itself with an event, campaign, or brand without paying for official sponsorship rights. The tactic is most visible in sports, concerts, and festivals, where official sponsors have invested substantially for exclusivity. Ambush marketers may use suggestive wording, event-themed imagery, athlete endorsements, venue-adjacent promotions, or social media campaigns implying a commercial connection with the event. Common Forms of Ambush Marketing Ambush marketing typically takes one of the following forms: Direct ambushing: using event names, logos, or mascots suggesting authorization Coattail ambushing: sponsoring an athlete or broadcaster connected with the event Subtle ambushing: themed advertising, venue-adjacent campaigns, or similar visual cues The legal analysis in each case turns on whether the marketing crosses from permissible event-based advertising into infringement, passing off, deception, or wrongful exploitation of goodwill, and the risk assessment is necessarily fact-specific. Thailand has no dedicated ambush marketing statute, so legality depends on execution. A campaign that merely comments on a public event may be permissible, but one that uses protected marks, creates consumer confusion, misrepresents sponsorship status, or makes unsubstantiated claims may trigger liability under various Thai laws, as laid out below. Ambush Marketing and Thailand’s Trademark Act The Trademark Act B.E. 2534 (1991) is the primary tool for addressing campaigns that use registered trademarks, event names, logos, mascots, or confusingly similar signs. The law gives registered trademark owners the exclusive right to use their mark for registered goods, and infringement risk arises when a nonsponsor uses an event mark or a confusingly similar sign in advertising. Even referential or playful use may create liability if it causes public confusion as to sponsorship or commercial connection. The law also preserves passing-off claims for unregistered marks. This matters because event names, taglines, or mascots may not always be

When Decree No. 186/2026/ND-CP (Decree 186) takes effect on July 15, 2026, it will introduce the most significant reform of Vietnam’s administrative IP enforcement framework since Decree 99/2013/ND-CP was issued in 2013. These changes are expected to make administrative enforcement faster, more accessible, and better suited to the realities of modern IP disputes. Below are the principal reforms and their practical implications for rights holders and enforcement practitioners. The End of Notarization and Consular Legalization Among the most welcome procedural changes is the abolition of the notarization and consular legalization requirement for powers of attorney (POA) submitted in administrative enforcement proceedings. Under the previous regime, foreign rights holders were generally required to execute a POA, then have it notarized and consular legalized (if seeking customs recordal). In practice, this process frequently delayed enforcement by four to eight weeks, often long enough for infringing goods to disappear before authorities could intervene. Decree 186 removes this bottleneck, now requiring only an original or certified copy of the POA. If the document is in a foreign language, a Vietnamese translation is sufficient, provided it is certified by a competent authority or confirmed by the authorized Vietnamese IP representative. Consular legalization and notarization are no longer required. For rights holders, the practical impact is substantial. Administrative enforcement files that previously took weeks to prepare can now be completed in a matter of days, allowing much faster responses in time-sensitive matters such as warehouse raids, border interventions, and trade-fair enforcement. The decree also introduces a useful administrative simplification. Where an original POA has already been submitted to the same enforcement authority and remains valid, applicants may rely on a copy of that earlier submission by identifying the previous case file. This eliminates unnecessary duplication for rights holders pursuing multiple enforcement actions before the same

Recycling, upcycling, and refill-packaging models are now widely promoted as ways to reduce waste, lower carbon emissions, and respond to consumer demand for sustainable products. However, complications arise when these environmentally driven trends intersect with intellectual property law—particularly where reused or altered packaging continues to display third parties’ registered trademarks. Adding to this complexity, Thailand’s draft Sustainable Packaging Management Act aims to introduce new environmental compliance obligations that businesses must navigate alongside existing trademark concerns. Recycling and upcycling packaging may infringe trademark rights, especially in cases not protected by the first-sale doctrine—the principle that a trademark owner’s rights over a particular mark-bearing product end once the owner first sells it. Furthermore, even refill packaging carries legal risk due to specific statutory prohibitions under Thai law. Compounding these challenges, the draft Sustainable Packaging Management Act will impose extended producer responsibility (EPR) obligations on manufacturers and brand owners, requiring them to manage packaging throughout its lifecycle. These overlapping legal frameworks could deter manufacturers from pursuing ESG-aligned business models unless businesses understand how to navigate both trademark and environmental requirements. Under Thai law, this issue remains uncertain because the Trademark Act does not expressly codify the first sale doctrine, also known as the exhaustion of trademark rights. Generally, this doctrine provides that once a trademark owner has lawfully sold goods bearing its trademark, the owner’s right to control further resale of those particular goods is exhausted. The rationale is that the owner has already received commercial benefit from the first authorized sale; therefore, the purchaser should be free to resell or otherwise dispose of the goods. Although the doctrine is not expressly codified in the Trademark Act, Thai courts have recognized it in relation to genuine goods and parallel imports, as seen in a Supreme Court Judgment No. 2817/2543 in which the

On July 7, 2026, the Trade Competition Commission of Thailand (TCCT) issued a press release announcing the establishment of two new subcommittees designed to intensify oversight of digital platforms and modern trade businesses. The formation of the digital platform subcommittee marks a significant escalation in competition enforcement following the TCCT’s Guidelines on Multi-Sided Platforms and E-Commerce Businesses, which took effect on March 25, 2026. Platform operators, sellers, and related service providers should expect heightened regulatory scrutiny and potential investigations into practices already flagged under the March guidelines. Two Dedicated Enforcement Bodies The first new body is the digital platform subcommittee—formally the Subcommittee on Supervision, Monitoring, and Prevention of Trade Conduct in Digital Platform Business. It is tasked with driving intensive oversight of digital platform businesses. It will coordinate with government agencies, the private sector, business operators, and other relevant stakeholders to supervise and prevent trade conduct that may affect competition, and to promote free and fair competition in the digital platform sector. The subcommittee will be composed of TCCT members and representatives from the Department of Internal Trade. The second body—the Subcommittee on Determining Guidelines and Action Plans Concerning Competition Conditions in Modern Wholesale and Retail Business—will study, analyze, and monitor market structure in modern wholesale and retail businesses, compile databases to analyze retail business concentration, assess impacts on small-scale operators, and propose supervisory measures for the retail sector. TCCT members will serve on the subcommittee alongside experts from government and private organizations, including the Office of Industrial Economics, the Office of Small and Medium Enterprises Promotion, the Thai SME Federation, and the Thai SME Council. Operational Impact for Industry Participants These subcommittees provide the TCCT with a focused mechanism to investigate various trade practices deemed unfair, and the TCCT has authority under the Trade Competition Act to issue cease-and-desist
