Registering a trademark gives you the exclusive right to use your mark and offers you protection against infringement of your Intellectual Property. Trademark Registration enhances your ability to apply the full force of the law against possible trademark violations and ensures that you are not unknowingly infringing on someone else’s trademark. We can help you with registering your trademarks, service marks, certification marks and collective marks in Thailand and worldwide.

Requirements for a Mark to be Accepted in Thailand

A mark must meet three requirements to be accepted for registration. It must be distinctive, not prohibited by law and not the same or similar to an already existing trademark held by others.



Examples of Characteristics Deemed Distinctive

  • A personal name, surname, name of a juristic person or trade name represented in a special manner and having no direct reference to the character and quality of the goods

  • A word or phrase that has no direct reference to the character of the goods and which is not deemed a geographical name as stated by the minister

  • Stylized letters and numerals,

  • A combination of colors represented in a special manner and an invented device

Not Prohibited by Law   


Marks must not be prohibited by law.

Examples of marks that are strictly prohibited:

  • Marks that disturb the public order or go against morality or public policy

  • Any marks that are identical or similar to medals, certificates,  diplomas issued by the Thai Government

  • Geographical identifications protected by law

  • Marks with references to the royal family

  • Emblems and flags of Thailand and foreign states

Not identical or similar to an already existing

trademark held by others.



To make sure that trademarks are not identical or similar we can check availability in advance.
