Trademark Registration

Protect Your Corporate Identity

Thailand does not have any international agreements on trademark ownership. If your trademark is not registered in Thailand it is in danger of being claimed by another party. To regain control of your trademark after it has been registered by another person, is expensive and will take years, Even then you may lose your trademark in Thailand unless you register it before someone else.

If you as the true owner then wanted to challenge the ownership of the mark you may submit a petition to cancel the registration at the Intellectual Property Court in Bangkok. This petition must be submitted within five years of the date that the previous registration of the mark in Thailand was approved, and the proof needed in order to cancel the registration is substantial .

The first step that an investor who owns the trademark should do, is protect their rights by registering the trademark at The Trademark Division of the Department of Intellectual Property (Ministry of Commerce).

In order to get the trademark registered it must:
  • be distinctive
  • not be the same as or similar to a trademark already registered by another person and not be otherwise prohibited by law.
Some of the issues associated with registering marks in Thailand are:


Determining whether a given mark is distinctive is with the discretion of the Registrar at the Trademark Division of the Department of Intellectual Property. A distinctive mark separates the goods or services with which the mark is used from other goods and services. It must have one of the following:

  • a combination of colors represented in a special manner, stylized letter(s), numeral(s) or invented word(s);
  • a word or words that has no direct reference to the character or quality of the goods and is not a geographical name designated by the Ministerial Notifications;
  • a personal name, a surname not being such according to its ordinary signification, a name of a juristic person or a tradename represented in a special manner;
  • the signature of the applicant for registration or some predecessor in his business or the signature of another person with his or her permission;
  • a representation of the applicant or of another person with his or her permission or of a dead person with the permission of his or her ascendants, descendants and spouse, if any;
  • an invented device.
Three of the most common issues which arise concerning whether a mark is distinctive:
  • Stylized Letter(s), and Invented Word(s)
  • No Direct Reference to the Character or Quality of the Goods
  • Exception: Proof of Use

If you have a trademark that has been extensively used in Thailand prior to submitting the trademark application can be deemed distinctive even if it does not comply with the above listed rules. This use must be such as adverts, promo pieces, letterhead, etc in Thailand.

Not the Same or Similar to a Trademark Registered by Another Person

If a mark is the same or similar to a mark previously registered by another party you will not be allowed to register it. Many of our clients have us do a search at the Trademark Division of the Department of Intellectual Property to determine whether anyone has previously registered the same or a similar mark in Thailand . They then know (before submitting the application) that the application may be rejected on this basis.

Not Prohibited by Law

The law specifically states that marks having the following characteristics cannot be registered:

  1. a mark, registered or not, which is identical with a well-known mark, as prescribed by the Ministerial Notifications, or so similar that the public might be confused as to the owner or origin of the goods;
