Thailand recorded over 15,000 trademark applications from foreign companies in 2024 alone — a figure that reflects how seriously international brands now treat brand protection in Southeast Asia.
For businesses sourcing products from the region or manufacturing across the supply chain, failing to register a mark before entering the Thai market can be a costly oversight.
The risk isn’t theoretical : counterfeit goods and trademark squatting remain persistent issues in Thailand, making early, structured intellectual property protection a strategic priority rather than an afterthought.
How trademark registration works in Thailand
The authority responsible for trademark registration in Thailand is the Department of Intellectual Property (DIP), operating under the Ministry of Commerce. All applications go through this single body, whether filed directly or through a licensed Thai attorney.
Foreign companies cannot file independently — they must appoint a local representative, which adds a layer of planning to the process.
The registration procedure follows a clear sequence. First, a trademark search is strongly recommended before any filing, to identify conflicting marks already on the register.
Then comes the official application, examination by the DIP, publication in the Trademark Journal, and finally registration — assuming no opposition is raised.
The typical timeline from filing to registration runs between 18 and 24 months, assuming no legal complications.
This delay matters enormously when you’re coordinating product launches, supplier contracts, or logistics across multiple sourcing markets. Planning trademark filings 12 to 18 months ahead of market entry is not overcautious — it’s simply rational.
Official fees at the DIP are relatively modest : approximately THB 1,000 per class at filing, with additional fees at registration. However, attorney costs, translation requirements, and potential opposition proceedings can push total costs significantly higher.
Budget between USD 500 and USD 1,500 per class for a straightforward registration handled by a reputable Thai IP firm.
| Step | Estimated duration | Key actor |
|---|---|---|
| Trademark search | 1–2 weeks | IP attorney / DIP database |
| Application filing | 1–3 days | Licensed Thai representative |
| Formal examination | 12–18 months | Department of Intellectual Property |
| Publication & opposition period | 90 days | Trademark Journal |
| Final registration | 1–2 months post-opposition | DIP |
Rights acquired and scope of brand protection
Thailand operates on a first-to-file system — not first-to-use. This distinction is critical. Unlike common law jurisdictions, prior use of a mark in commerce does not grant ownership rights under Thai law.
The entity that files first generally wins, regardless of who actually invented or used the brand earlier. Trademark squatting exploits this rule systematically.
Once registered, a trademark grants its owner exclusive rights for 10 years, renewable indefinitely in successive 10-year periods. The protection covers the specific classes of goods or services designated at filing under the Nice Classification system.
A fashion brand protecting its logo in Class 25 (clothing) has no automatic protection in Class 18 (bags) unless it files separately.
When managing multiple suppliers or product lines across a supply chain, it’s worth building a clear IP map : which marks are registered, in which classes, and in which markets.
Gaps in this coverage are exactly the kind of vulnerability that sophisticated counterfeiters exploit — and that surface too late when you lack systematic visibility across your commercial operations.
- Well-known marks may receive broader protection under Section 8 of the Thai Trademarks Act
- Unregistered marks have very limited legal recourse under Thai law
- Trade dress and three-dimensional marks can be registered but face higher scrutiny
- Collective marks and certification marks follow a separate registration track
Enforcement and legal remedies against trademark infringement
Trademark enforcement in Thailand operates through both civil and criminal channels — an important distinction that gives brand owners genuine leverage. The Thai Trademarks Act provides for criminal penalties including imprisonment of up to four years and fines up to THB 400,000 for willful infringement.
Criminal prosecution, while slower, creates a deterrent effect that civil injunctions alone often cannot.
On the civil side, rights holders can seek injunctions, damages, and destruction of infringing goods. Thai courts have shown increasing willingness to grant ex parte injunctions in urgent cases, particularly where evidence of ongoing infringement is well-documented.
The quality of your documentation matters : purchase records, test buys, photographs, and supply chain traceability data all strengthen your position substantially.
Customs recordation is another powerful tool. By recording a registered trademark with the Thai Customs Department, brand owners enable border agents to detain suspected counterfeit shipments before they reach distribution channels.
This upstream intervention fits naturally into a proactive supply chain monitoring approach — catching problems at the border is far less damaging than pursuing infringers downstream.
For cross-border sourcing operations, enforcement also means monitoring your own suppliers.
Unauthorized sublicensing, use of your marks on unapproved product variants, or sales outside agreed territories are forms of contractual and trademark breach that require clear contractual language and active oversight to detect early.
Building a durable trademark strategy for the Thai market
Registering a trademark in Thailand is not a one-time task — it requires active maintenance and strategic renewal.
A registration lapses if not renewed within the deadline window, and non-use for three consecutive years can expose a mark to cancellation proceedings initiated by third parties.
Beyond renewal, consider filing in additional Nice classes as your product range evolves. A brand that started in consumer electronics may expand into accessories or software — and each new category deserves dedicated IP coverage before commercial activity begins, not after.
Connecting your IP calendar to your broader sourcing and product development roadmap makes this far easier to manage systematically.
Thailand is also a signatory to the Paris Convention and a member of WIPO, meaning you can leverage a home-country priority filing date when entering the Thai market.
This priority window — six months from your original filing date — is often underused by companies expanding across Southeast Asia. Acting within this window can neutralize trademark squatters before they even have the opportunity to move.
