Overview of Thailand Trademark Registration

The Department of Intellectual Property (DIP) under the Ministry of Commerce of Thailand is responsible for trademark registration management. Registered trademarks are valid for 10 years from the date of application and can be renewed indefinitely. After registration, they are fully protected under Thai law.

🛡️

Legal Protection

After successful registration, exclusive rights are obtained throughout Thailand, allowing the legal stop of infringement, including trademark violations on cross-border e-commerce platforms.

⏱️

Registration cycle

If successful, the entire registration process takes about 12-18 months, including key stages such as formal examination, substantive examination, announcement, and approval.

International alignment

Thailand is a member of the Madrid System and can apply for international trademark protection through the Madrid Protocol, covering the Thai market.

Trademark registration process

Trademark registration in Thailand follows a strict legal process; below are the standardized application steps

1. Trademark search

Searching DIP databases to assess trademark registrability, avoid conflicts with prior trademarks, and reduce the risk of rejection, Thailand adopts the 11th edition of the Nice Classification.

2. Submit the application

Prepare the complete application materials, submit the registration application to DIP, pay the official fee, and obtain the application receipt and application number.

3. Formal review

DIP reviews the completeness and standardization of application documents. If they do not meet the requirements, they must be corrected within a specified period, which is generally three months.

4. Substantive Examination

The examination period for examining the distinctiveness, legality, and similarity of the trademark to the prior trademark takes about 6-9 months.

5. Announcement of objections

Trademarks are published in the official Thai trademark gazette for 90 days. Any interested party may raise an opposition during this period, and if there is no objection, registration will be approved.

6. Issuance of certificates

After completing all examination procedures, DIP issues a trademark registration certificate, officially taking effect with a validity period of 10 years.

Frequently Asked Questions

Answering your common questions about trademark registration in Thailand

Yes, Thai law stipulates that non-Thai residents or companies not registered in Thailand must entrust a local Patent and Trademark Agent (TBA) to apply for trademark registration. Local agents are familiar with DIP's examination rules and Thai language communication requirements, which can effectively improve the success rate of registration.

Yes, you can. If the trademark application is rejected by DIP, the applicant may file a request for review within 60 days of receiving the notice of rejection, along with relevant evidence and reasons. If the review is still rejected, an appeal can also be filed with the Central Intellectual Property and International Trade Court of Thailand.

Yes. Thai trademark law stipulates that if a registered trademark has not been actually used in Thailand for three consecutive years after registration, any interested party may apply to cancel the trademark (revoke non-use). Therefore, after registration, it is necessary to ensure the trademark is actually used in Thailand and to retain complete evidence of use (such as sales vouchers, advertising materials, etc.).

Thai trademarks are valid for 10 years. Renewal applications must be submitted within 90 days before the expiration date, with a grace period of 6 months after expiration (additional late fees apply). No proof of use is required for renewal; only the renewal application and official fees are paid. After renewal, the validity period is extended by 10 years, allowing unlimited renewal.

Yes, it is allowed. Thailand allows the registration of Chinese trademarks, but a Thai/English translation of the trademark must be provided to clarify the meaning and pronunciation of the trademark. Pure graphic trademarks do not require translation, but the graphic must be distinctive and not violate Thailand's public order and good morals.
