A Thai trademark registration protects your local or foreign brands in Thailand against any kind of infringement and counterfeiting of your intellectual property. Registering a trademark enables you to enforce your rights and makes sure that you don't accidentally infringe on the trademark held by others.

When registering a foreign trademark, the Thai law can only provide limited protection at its best. Thailand is not obligated to international conventions or treaties that provide reciprocal enforcement associated with trademarks. Only with the trademark registration, you can be assured of your enforceable rights. While the registration of the trademark can be a lengthy and cumbersome process in Thailand, your trademark is protected from the day your registration application is submitted.

For the registration of the trademark, the business should have a principal address in Thailand. Foreign applicants can only apply for trademark registration by appointing a Thai agent and granting him the power of attorney. The trademark application must be filed in the Thai language.

Cloud 7 Legal Services will assist you throughout the registration process to ensure fast approval of your trademark registration. Before forwarding your trademark registration application to the Trademark Registrar, we ensure that the trademark to be registered is not similar to any other mark that has already been registered. Upon subsequent submission of the application, our legal experts will give explanations, statements and suggestions to the Trademark Registrar on your behalf. Our proactive involvement and response to queries of the Trademark Registrar ensure timely approval of your application.

For the trademark registration, the applicant needs to file an application in the Thai language with the Department of Intellectual Property. Additionally, the application must bear the principal address of the applicant and an attachment of a sample product. If the applicant is a foreigner, the business office or premises will be considered as the domicile.

A duly filed registration application will be published in the Trademark Gazette for 90 days and the payment of the registration fee will be due as long as no one files an objection during this period of time.

For the registration application, the applicant is required to produce certain documents/information as given below:

  • The Trademark logo with accurate color.
  • A copy of company affidavit if the applicant is a foreign company and an original company affidavit if the applicant is a Thai company.
  • A duly signed passport copy of the authorized director(s).
  • A duly signed Power of Attorney. It should be notarized if it is signed from abroad.



The trademark registration applications are coordinated by the current 11th edition of the Nice Classification system hence making filing simpler as the goods or services will be classified as same in all countries who use this system. Additionally, the Nice Classification is available in several languages making it easy for the applicants when filing from abroad. If the applicant needs to file for more than one class, a separate application for each classification must be filed.
