Thailand’s first-to-file trademark system has a serious vulnerability: it lacks both an explicit mechanism for refusing bad-faith registrations and any means of invalidating them in court after the five-year limitation period has expired. While brand owners worldwide confront trademark squatting, Thailand’s statutory silence stands out, particularly in light of AIPPI’s 2017 Resolution Q249, which recommended that every jurisdiction provide clear tools to address bad faith at all stages of the trademark lifecycle. Nearly a decade later, Thailand has yet to act. This article proposes a concrete reform blueprint, drawing on the legislative models of China, the United Kingdom, and the European Union. The Statutory Gap Under the Thai Trademark Act B.E. 2534, no provision expressly authorizes examiners to reject an application on grounds of bad faith. Section 8(10) addresses well-known marks but offers no relief where the targeted mark lacks well-known status. Practitioners have resorted to Section 8(9)—which bars marks “contrary to public order, morality, or public policy”—as a workaround. However, this provision was designed to address the characteristics of the mark itself, not the applicant’s intent. Thai Supreme Court decisions have split on whether it can reach bad-faith conduct, creating persistent legal uncertainty. The gap extends beyond examination. Civil actions to cancel a bad-faith registration must be brought within five years—a deadline that frequently expires before foreign brand owners discover the squatted mark. Cancellation through the Board of Trademarks remains available but is slow, costly, and subject to court appeal, leaving bad-faith registrations in force during protracted proceedings. The system effectively rewards squatters and penalizes legitimate owners. Lessons from International Best Practices Several major jurisdictions have already closed this gap. China’s 2019 amendment to Article 4 of the Trademark Law introduced an absolute ground for refusal: “bad faith trademark applications without intent to use shall be rejected.” Bad

Thailand’s Office of the Consumer Protection Board (OCPB) has released for public comment a draft bill to amend the Consumer Protection Act B.E. 2522 (1979), the country’s foundational consumer protection legislation. The draft amendment aims to modernize the nearly five-decade-old framework to address the rapid growth of digital commerce, online advertising, influencer marketing, and new business models. The public consultation period is open until October 10, 2026. Expanded Definitions Covering Digital Commerce The draft significantly broadens several core definitions to capture modern commercial activities: “Consumer” is expanded to include natural persons and nonprofit juristic persons who purchase or receive services, including those solicited by businesses and end users who do not directly pay for the goods or services. “Business operator” now explicitly covers advertising business operators and hired advertising persons, such as influencers and content creators. “Advertising media” is expanded to include digital platforms, social media, and social media user accounts. “Label” now encompasses electronic labels—symbols, codes, or other electronic formats displaying product information. Influencer and Advertising Disclosure Requirements In addition to these expanded definitions, “hired advertising person for selling goods or services” is a new definition covering influencers, content creators, live streamers, affiliate marketers, and virtual online media operators who receive monetary compensation or other benefits for advertising goods or services. Hired advertising persons—including influencers and content creators—must disclose to consumers that content is advertising and reveal their relationship with the business owner. Disclosure is required when the business owner employs the advertiser, pays or provides other benefits for the advertisement, or provides free or discounted products or services. These requirements apply where consumers would not otherwise know that the business has a connection to the person presenting the content. Labeling Requirements for Importers The draft introduces a clearer labeling obligation for importers of label-controlled goods, who must
