General Information

Legal Notes: The Thai trademark law follows the English Act of 1991. In case no complication emerges, especially for mark applications with proof of use, the Registrar shall grant registration from 10 to 12 months. Prior use of a mark is not required but in case of conflict, prior use gives better title. By legal action, a mark may be cancelled for non-use for 3 years.

Assignments must be with the business but a mere statement of transfer of goodwill in the business is deemed sufficient. Licensing is by private agreement only.

Term of Tradmark Protection

The registration of a trademark is valid for 10 years from the date of application and may be renewed within 90 days before the expiration of the trademark registration

Presenting false evidence while registering a trademark is liable to a term of imprisonment not exceeding 6 months or a fine not exceeding 10,000 Baht, or both.

Anyone who forges another person’s trademark, registered in the Kingdom, or who sells, possesses for sale, or brings into the Kingdom objects with a forged trademark, shall be punishable by imprisonment not exceeding 4 years or a fine not exceeding 400,000 Baht, or both.
