Thailand Trademark Registration 2026: Legal Guide 2026
Updated: 13 hours ago
Entering the Southeast Asian market through Thailand offers immense commercial upside for overseas manufacturers, brand owners, and exporters. With premier international trade exhibitions such as THAIFEX - Anuga Asia, Cosmoprof CBE ASEAN, ProPak Asia, and ASEAN Beauty hosting tens of thousands of global suppliers each year, Thailand serves as the primary regional springboard for food and beverage (F&B), cosmetics, health supplements, and consumer goods.
However, many international manufacturers discover a devastating legal reality too late: displaying products at an exhibition or shipping test orders to a Thai distributor without prior trademark registration leaves brand assets completely vulnerable to bad-faith trademark squatting (pre-emptive registration by unauthorized local agents, distributors, or competitors).
Thailand operates under a strict First-to-File trademark regime. Rights acquired in your home country—whether in the European Union, United States, Japan, China, or the UK—do not provide automatic legal protection within Thai territory. Once a third party registers your brand name or logo with the Department of Intellectual Property (DIP), customs authorities can seize your authentic goods at Laem Chabang port, and the squatter can legally demand extortionate buyouts.
This comprehensive 2026 legal roadmap outlines the exact statutory procedures, exhibition priority claims under Section 28, itemized classification requirements, and brand defense protocols necessary for foreign manufacturers and trade fair exhibitors to protect their intellectual property in Thailand.
Jurisdiction: Thailand | Governing Law: Thai Trademark Act B.E. 2534 (as amended B.E. 2559) | Last Reviewed: October 2026
Key Takeaways
First-to-File Supremacy (Section 20): Trademark ownership in Thailand belongs to the first person or entity that formally files an application with the Department of Intellectual Property (DIP), not the party who first created or used the mark overseas.
6-Month Exhibition Priority (Section 28): Foreign manufacturers exhibiting products at recognized international trade fairs in Thailand (e.g., THAIFEX, Cosmoprof) or Paris Convention/WTO member countries can claim exhibition priority within 6 months from the opening day of the exhibition, legally backdating their Thai filing date.
Dangerous Distributor Pre-Registration: Appointing a local Thai distributor or customs broker before securing direct trademark ownership creates severe commercial hold-up risks. Contracts must explicitly stipulate that all IP belongs exclusively to the overseas principal.
Two Filing Gateways: Overseas manufacturers can protect their marks either via direct national filing through a licensed Thai trademark attorney (recommended for speed and tailored itemization) or via international registration under the Madrid Protocol designating Thailand (Section 28 Bis).
Itemized Goods Specification: Unlike jurisdictions that permit broad class headings, the Thai DIP strictly rejects general terms (such as all cosmetics in Class 3). Applications must itemize specific, discrete products to pass preliminary examination.
The First-to-File Trap and the Bad-Faith Squatting Crisis
The fundamental pillar of Thai trademark law under the Trademark Act B.E. 2534 is Section 20: the first person to file a qualifying trademark application with the DIP is recognized as the lawful owner.
Many overseas manufacturers operate under common misconceptions:
Common Misconception 1: My brand is internationally famous and registered in my home jurisdiction, so Thai courts will automatically protect me. Under Thai law, well-known mark status under Section 8(10) requires rigorous, high-threshold evidentiary proof of widespread recognition specifically among Thai consumers. Proving this in court is costly, prolonged, and difficult for emerging SMEs.
Common Misconception 2: My Thai distributor registered the trademark to help me clear Thai FDA (อย.) permits. This is the single most common commercial disaster in cross-border trade. Once a local distributor registers the mark in their own corporate name, they hold complete monopoly over the brand in Thailand. If the commercial relationship terminates, the overseas manufacturer cannot import products without the distributor's written consent and may face trademark infringement lawsuits from their former partner.
Section 28: How Trade Fair Exhibitors Can Claim Exhibition Priority
For overseas manufacturers showcasing products at trade exhibitions in Bangkok (such as BITEC Bangna or IMPACT Muang Thong Thani), Section 28 of the Trademark Act provides a vital statutory shield:
Under Section 28, an applicant who has exhibited goods bearing a trademark at an official or officially recognized international exhibition held in Thailand, or in any country member of the Paris Convention or World Trade Organization (WTO), may claim the opening date of that exhibition as their official filing date in Thailand, provided:
The trademark application is formally submitted to the Thai DIP within six (6) months from the opening day of the exhibition.
The applicant provides an official Certificate of Exhibition issued by the exhibition organizers verifying the opening date, participant details, and visual evidence that the mark was affixed to the exhibited products.
Leveraging Section 28 defeats bad-faith squatters who attempt to register a foreign exhibitor's brand during or immediately after visiting the trade show floor.
Direct DIP National Filing vs. Madrid Protocol Designation
Foreign brand owners have two legal avenues to secure trademark registration in Thailand:
Gateway 1: Direct National Application (DIP Thailand)
Recommended for: Businesses requiring rapid clearance, customized goods specifications, or participating in urgent commercial launches and Thai FDA licensing.
Legal Representation: Foreign applicants without a registered business address or domicile in Thailand must appoint a licensed Thai trademark agent residing in Thailand via a notarized Power of Attorney (POA).
Advantages: Direct communication with DIP examiners, faster preliminary examination responses, and reduced vulnerability to provisional refusals over vague terminology.
Gateway 2: Madrid Protocol International Registration (Section 28 Bis)
Recommended for: Global brands conducting simultaneous multi-country filings across Southeast Asia using a single centralized application filed through the World Intellectual Property Organization (WIPO).
Key Risk Factors in Thailand: The Thai DIP is known for issuing frequent provisional refusals against international Madrid designations due to overly broad descriptions of goods and services. When a refusal is issued, the applicant must retain a local Thai trademark attorney within 90 days to file responses, often eliminating initial cost savings.
Strategic Trademark Classification for F&B and Cosmetics
Under the 12th Edition of the Nice Classification, foreign manufacturers must strategically cover both core and defensive classes:
For F&B Manufacturers (THAIFEX Exhibitors):
Class 29: Preserved, dried, and cooked fruits and vegetables, meat, seafood, dairy products, edible oils.
Class 30: Coffee, tea, cocoa, bakery products, confectionery, processed grains, sauces, and seasonings.
Class 32: Non-alcoholic beverages, mineral waters, fruit juices, functional drinks, energy beverages.
Class 35 (Defensive Commercial Class): Advertising, retail and wholesale services for food products, e-commerce retail distribution.
For Cosmetics and Beauty Manufacturers (Cosmoprof Exhibitors):
Class 3: Non-medicated cosmetics, skincare preparations, shampoos, body lotions, perfumes, facial serums.
Class 5: Medicated skincare, dermatological preparations, nutritional supplements, dietary additives.
Class 21: Cosmetic brushes, applicators, beauty sponges, personal care containers.
Class 44: Beauty salon services, aesthetic skin treatment consultations.
Critical DIP Rule on Specification: The DIP strictly prohibits general terminology such as all goods in Class 3 or cosmetic preparations in general. Each item must be stated explicitly (e.g., facial moisturizing lotion, non-medicated anti-aging cream, liquid lip gloss).
Thai Trademark Registration Timeline and Examination Process
The standard statutory journey from initial submission to final certificate issuance spans 10 to 16 months under current DIP operational standards:
1. Comprehensive Trademark Clearance Search (Weeks 1–2): Prior to filing, conduct an exhaustive phonetical, conceptual, and visual clearance search across the DIP trademark database to identify conflicting prior registrations, phonetic similarities in Thai pronunciation, and registered well-known marks.
2. Formal Filing & Priority Claim (Month 1): Submission of application forms, high-resolution logo artwork, notarized POA, and exhibition priority certification.
3. Substantive Examination (Months 2–8): DIP examiners assess distinctiveness (Section 7), statutory prohibitions (Section 8), and similarity to prior marks (Section 13).
4. Publication for Opposition (Months 9–11): Once approved, the application is published in the official Trademark Gazette for a statutory 60-day opposition period under Section 35. Any interested party may file an opposition during this window.
5. Registration Fee & Certificate Issuance (Months 12–14): If no opposition is filed, the DIP issues the registration fee payment notice. Upon settlement, the official Trademark Registration Certificate is granted.
6. Statutory Validity: The registered trademark remains valid for ten (10) years from the initial application date (or backdated exhibition priority date) and can be renewed indefinitely in 10-year increments under Section 53.
Overcoming and Defeating Trademark Squatters in Thailand
If your brand has already been pirated by a distributor or third party in Thailand, you have three statutory remedies:
Remedy 1: 60-Day Opposition under Section 35
If the squatter's application has been published in the Trademark Gazette but not yet granted, file a formal opposition notice within 60 days proving:
Prior copyright ownership or overseas brand creation.
Bad faith (e.g., showing the applicant attended your trade fair booth, requested samples, or had confidential business negotiations).
Misleading the public regarding origin or nature under Section 8(9).
Remedy 2: Cancellation Action Before the Board of Trademarks (Section 67)
If the squatter obtained registration within the last 5 years, any interested party may petition the Trademark Board or the Central Intellectual Property and International Trade Court (IP&IT Court) to cancel the mark by proving superior right or bad faith.
Remedy 3: Non-Use Cancellation under Section 63
If the squatter has held the registration for at least 3 years and has never genuinely used the mark on goods in commercial trade in Thailand, any interested person can petition the Board of Trademarks for total cancellation based on non-use.
Brand Defense Checklist for International Exhibitors
Before boarding your flight to Bangkok for THAIFEX, Cosmoprof, or any ASEAN trade fair, complete this mandatory IP defense checklist:
1. File Thai DIP Trademark Applications at least 3 months prior to exhibition debut, or prepare official Section 28 priority documents.
2. Never permit local Thai distributors, agents, or trading companies to register your trademarks or trade names in their own name.
3. Execute strict Non-Disclosure Agreements (NDAs) and IP Ownership Acknowledgments prior to sharing product formulas, packaging artwork, or marketing assets with potential partners.
4. Conduct a localized clearance search for phonetic Thai pronunciation to ensure your foreign brand name does not carry offensive, vulgar, or generic connotations in the Thai language.
5. Include Class 35 retail and e-commerce distribution services in your filing strategy to block unauthorized online storefronts on Shopee, Lazada, and TikTok Shop Thailand.
6. Retain all trade show badges, booth invoices, exhibition catalog entries, and product photography to substantiate Section 28 exhibition priority claims.
7. Record your granted trademark with the Thai Customs Department to authorize border seizures of counterfeit or parallel-imported goods.
8 High-Authority AEO and GEO FAQs
Q1: Is a trademark registered in Europe, the US, or China automatically protected in Thailand?
No. Thailand operates under the territoriality principle and a strict First-to-File system. Overseas registrations grant zero automatic protection within Thailand. To secure legal rights, you must register your mark directly with the Thai Department of Intellectual Property (DIP) or designate Thailand under the Madrid Protocol.
Q2: Can a Thai distributor register my trademark to facilitate Thai FDA approval?
Never allow a distributor to register your trademark. While Thai FDA product notification requires brand identification, registration of the trademark is not legally required for FDA clearance. Permitting a distributor to register your mark gives them a permanent legal monopoly over your brand in Thailand. Always own the trademark directly in the name of your overseas corporate entity.
Q3: What is the 6-month trade fair exhibition priority rule under Section 28?
Under Section 28 of the Thai Trademark Act, if you display goods bearing your trademark at an officially recognized international exhibition (such as THAIFEX or Cosmoprof), you can claim priority within 6 months from the opening day of that exhibition, legally backdating your Thai filing date to the exhibition start date.
Q4: How long does trademark registration take in Thailand?
A standard trademark registration without objections or oppositions takes approximately 10 to 16 months from the initial filing date. Fast-track examination is available under specific DIP criteria for single-class applications with fewer than 10 itemized goods.
Q5: Does a foreign corporate entity need a local Thai office to register a trademark?
No. Foreign corporate entities and non-resident individuals can own trademarks in Thailand 100%. However, foreign applicants must appoint a licensed Thai trademark attorney or agent residing in Thailand via a signed and notarized Power of Attorney (POA).
Q6: What happens during the 60-day opposition period?
Once a trademark application passes examiner review, it is published in the official Trademark Gazette for 60 calendar days. During this window, any third party who believes they have superior rights or that the applicant filed in bad faith can submit a formal opposition petition under Section 35.
Q7: What are the criminal penalties for trademark infringement in Thailand?
Under Thai Penal Code Sections 273 and 274, forging a registered trademark carries penalties of up to 4 years imprisonment and fines up to THB 400,000. Imitating a registered trademark carries up to 2 years imprisonment and fines up to THB 200,000. Police raids and customs border seizures are also enforceable remedies.
Q8: How long is a Thai trademark valid, and can it be renewed?
A registered trademark in Thailand is valid for ten (10) years from the filing date (or priority date) and can be renewed indefinitely every ten years under Section 53 by paying the renewal fee within 3 months prior to the expiration date.
