Registering a trademark in Thailand is a crucial step for protecting your brand identity. It helps prevent others from using your brand name, logo, or slogan without permission. If you are a foreign founder or run a foreign-owned SME, understanding the trademark registration process in Thailand is essential for compliant business operations. We will walk you through the key steps, what you need to prepare, and practical tips to navigate the process smoothly.
Understanding the Trademark Registration Process Thailand
Trademark registration in Thailand is governed by the Department of Intellectual Property (DIP). The process involves several stages, each with specific requirements and timelines. The goal is to secure exclusive rights to your trademark within Thailand, which can be vital for your business reputation and legal protection.
Here is a structured overview of the trademark registration process:
Trademark Search
Before applying, conduct a thorough search to check if similar trademarks already exist. This reduces the risk of rejection or opposition later.
Filing the Application
Submit your trademark application to the DIP. You will need to provide details such as the trademark image, the goods or services it covers, and applicant information.
Formal Examination
The DIP reviews your application for compliance with formal requirements. If there are issues, you may be asked to correct them.
Substantive Examination
The DIP examines whether your trademark is distinctive and not conflicting with existing marks.
Publication in the Trademark Journal
If the application passes examination, it is published for opposition. Third parties have 90 days to file objections.
Registration and Certificate Issuance
If no opposition is filed or resolved in your favor, the DIP registers the trademark and issues a certificate.
Renewal
Trademark registration lasts 10 years and can be renewed indefinitely every 10 years.

What You Need to Prepare for Trademark Registration
Preparation is key to a smooth trademark registration process. Here is a checklist of what you should have ready before filing:
Clear Trademark Representation
Provide a clear image or word mark of your trademark. For logos, use high-quality digital files.
List of Goods or Services
Identify the specific goods or services your trademark will cover. Thailand follows the Nice Classification system, so classify your products accordingly.
Applicant Information
Include full legal name, address, and nationality of the applicant. For foreign applicants, a local agent or representative is usually required.
Power of Attorney (if applicable)
If you use an agent or lawyer, prepare a signed power of attorney authorizing them to act on your behalf.
Filing Fees
Be ready to pay the official filing fees. Fees vary depending on the number of classes and type of trademark.
Supporting Documents
If your trademark includes non-standard elements (like colors or sounds), prepare additional explanations or samples.
Practical Tips to Avoid Common Pitfalls
Trademark registration can be complex, especially for foreign applicants. Here are some practical recommendations to reduce risks and delays:
Conduct a Comprehensive Search
Use the DIP’s online database or hire a professional to ensure your trademark does not conflict with existing marks.
Choose Distinctive Marks
Avoid generic or descriptive terms that may be rejected. Unique and creative marks have a better chance of approval.
Use a Local Agent
Foreign applicants must appoint a local agent. Choose someone experienced in intellectual property law in Thailand.
Respond Promptly to Office Actions
If the DIP requests clarifications or corrections, respond within the given timeframe to avoid abandonment.
Monitor the Publication Period
Keep track of the 90-day opposition window and be prepared to defend your trademark if challenged.
Plan for Renewal
Mark your calendar for renewal deadlines to maintain your trademark rights without interruption.
