A trademark application normally takes approximately 8 to 14 months to proceed to registration if no objection from the Registrar or opposition from an interested party is encountered. There are three steps to registering a trademark in Thailand: 

1. The application will be examined by the Registrar, who may require amendments to the application and or object to registration of the application. If necessary, an appeal against the Registrar’s required amendments and or objections may be filed with the Trademark Board.

2. Once the mark is accepted for publication, the mark will be advertised in the Thai Trademark Gazette. An opposition may be filed with the Registrar by any interested party during the 90 day period starting from the date of publication. The decision of the Registrar on the opposition may be appealed to the Trademark Committee by either party and the decision of the Trademark Committee may in turn be appealed to the Central Intellectual Property and International Trade Court.

3. Finally, the Registrar will request payment of the registration fees.  Upon payment of the registration fees, the Certificate of Registration will be issued

An applicant who has filed an application in a foreign country may claim the first foreign filing date as the filing date in Thailand if the first foreign application was filed not more than six months prior to application in Thailand and the applicant is a Thai national or is based in Thailand, or is a national of or is based in a country which accords reciprocal rights to Thai nationals. Please note that the deadline for filing a priority application is the day before the expiration of the six month period from the date of first filing.

The duration of a trademark registration is 10 years from the date of application. An application to renew must be filed during the 90-day period immediately preceding its expiry date. A trademark may be renewed an indefinite number of times.

Although it is not necessary to file a declaration or evidence of use in order to maintain registration, failure to use the mark without good reason for any consecutive three year period will render registration of the mark vulnerable to cancellation. To satisfy the use requirements, use of the mark must be by the registered owner or registered licensee.  In the case of non-use, any interested party may file a cancellation petition with the Trademark Committee. 

Trademark assignment and license agreements must be in writing and registered with the Registrar. Such agreements must clearly identify the trademarks by description, application, registration and class. In the case of license, the goods or services to be licensed must also be clearly identified and the agreement must contain conditions to insure effective control by the registered owner of the goods over the quality of the goods or services.
