Register Your Trademark in Thailand

To check if your trademark is available in Thailand, you should conduct a search using the DIP’s official online trademark database, which allows you to look for identical or similar registered and pending marks. You may also the WIPO Global Brand Database to broaden your search.

Emerhub can help conduct trademark research before you begin your application.

The trademark registration process in Thailand typically takes between 9 to 18 months, depending on various factors. After filing the application, the DIP conducts a formal and substantive examination, usually completed within about 9 months. If no objections arise, the application is published in the Official Gazette, triggering a 60-day opposition period. If opposed, the resolution process can extend the timeline significantly, sometimes by several years if appeals occur. If unopposed or after successful defense against opposition, the applicant pays the registration fee, and the trademark is registered, valid for 10 years from the filing date. 

The official application fee is approximately THB 5,000 for up to five classes of goods or services, with an additional THB 9,000 charged from the sixth class onward. There are also smaller fees such as a THB  500 disclosure fee and a THB 600 fee for granting the registration certificate. 

If you file a right-of-way ownership application, the fee is around THB 2,000. Renewal fees are about THB 5,000 per class and must be paid within 90 days before expiration to maintain protection. Additional fees may apply for late renewals or oppositions.

If someone opposes your trademark application in Thailand, the Registrar will notify you immediately. Afterwards, you must file a counterstatement within 60 days of receiving the opposition notice. Failure to respond within this period results in abandonment of your application. 

After you submit the counterstatement, both parties may present evidence, and the Registrar will review the case and issue a decision. If either party disagrees with the Registrar’s decision, they can appeal to the Trademark Board within 60 days. They may also subsequently appeal to the Intellectual Property and International Trade Court and higher courts if necessary.

A registered trademark is valid for 10 years from the filing date and can be renewed indefinitely in successive 10-year periods. The trademark owner must apply for renewal within 90 days before the expiration date. If the renewal is not filed within this period, there is a grace period of up to 6 months after expiration during which renewal is still possible, but it incurs an additional late fee of about 20% on top of the normal renewal fee. 

After filing a trademark application in Thailand, amendments to the application are limited and generally restricted to non-essential particulars. According to the Trademark Act and related regulations, you cannot amend essential elements of the trademark itself or add goods/services to the application once filed; such changes require filing a new application. 

Amendments to the trademark specimen itself are usually only allowed at the registrar’s request, typically to remove specific elements from the logo. Changes like name or address updates require supporting official documents and take several months to process.
