FAQs Relating to Trademark Registration

Trademark registration in Thailand helps protect your brand name, logo, or mark from unauthorized use. Registering a trademark gives you exclusive rights under Thai law and strengthens your ability to enforce those rights against infringement. Understanding the types of trademarks recognized in Thailand is an important first step before filing an application.

What is a Trademark?

A trademark is a recognizable sign, design, word, symbol, or expression that distinguishes the products or services of one business or source from those of others. Any individual, business organization, or legal entity may own a trademark and apply for trademark registration in Thailand.

What types of trademarks does Thailand recognize?

Thailand recognizes the following types of marks:

  • Trademarks
  • Service Marks
  • Collective Marks
  • Certification Marks

Service Mark

A service mark is a type of trademark used to identify services rather than goods. It allows businesses to distinguish their services from those of others.

Certification Mark

A certification mark is a mark used by its owner to certify that the goods or services of another person meet certain standards, such as origin, quality, composition, method of production, or other specified characteristics.

Collective Mark
A collective mark is a trademark or service mark used by members of the same association, group, cooperative, union, or other organization, whether public or private, to indicate that the goods or services originate from members of that group.

Is Trademark Registration Compulsory in Thailand?

Trademark registration is not compulsory in Thailand. However, registering a trademark provides significant legal and commercial advantages that are strongly recommended for brand protection.

What Are the Advantages of Trademark Registration?

Registering a trademark offers stronger legal protection against infringement and counterfeiting, as it protects a company’s name, logo, or mark and grants the owner exclusive nationwide rights under Thai law.

A registered trademark also helps deter others from using or applying for the same or a similar mark. Once registered, the trademark appears in official trademark search records, which may discourage third parties from proceeding with conflicting applications.

In addition, trademark registration provides the owner with stronger legal remedies. Registered trademark owners are generally in a better position to enforce their rights and pursue legal action against infringers through administrative, civil, or criminal proceedings.

How Can a Trademark Be Eligible for Registration?

A trademark is eligible for registration in Thailand if it is distinctive and not confusingly similar to a trademark already registered by another person. It must not contain any characteristics prohibited under Section 8 of the Thailand Trademark Act B.E. 2534 (with B.E. 2543 amendment).

Additionally, the applicant or their agent must have an office or address in Thailand where the Registrar can send official communications.

What Types of Trademarks Cannot Be Registered Under Thai Law?

According to Section 8 of the Trademark Act B.E. 2534 (with B.E. 2543 amendment), the following types of marks cannot be registered in Thailand:


  • State or Royal Symbols
  • State arms or crests, royal seals, Chakkri emblems, and emblems or insignia of royal orders and decorations.

  • National and Official Flags
  • National flags of Thailand, royal standard flags, or other official flags.

  • Royal Names or Monograms
  • Names, monograms, abbreviations, words, emblems, or representations signifying the King, Queen, Heir to the Throne, or members of the royal family.

  • Foreign or International Emblems
  • Official emblems, names, monograms, or flags of foreign states, heads of states, or international organizations, unless permission is granted by the competent authority.

  • Red Cross Symbols
  • Official emblems of the Red Cross or the words “Red Cross” or “Geneva Cross.”

  • Medals, Certificates, or Diplomas
  • Marks resembling medals, diplomas, or certificates awarded at trade exhibitions or competitions held by Thai or foreign governments or international organizations, unless the applicant actually received the award and uses it in connection with the trademark.

  • Marks Contrary to Public Order or Morality
  • Any mark that is contrary to public order, morality, or public policy.

  • Well-Known Marks
  • Marks identical or confusingly similar to well-known marks under Ministerial Notifications, where the public might be misled about the owner or origin of goods.

  • Geographical Indications
  • Marks that are protected as geographical indications under Thai law.

    How Long Does Trademark Registration Take?

    Generally, 6 to 12 months, depending on:

    • The completeness of the application
    • Whether objections or oppositions arise
    • Whether the application qualifies for fast-track examination

    Complex cases or those requiring amendments may take longer.

    How Long Is Trademark Protection Valid?

    A registered trademark provides protection for 10 years from the application-filing date.

    The registration can be renewed indefinitely in successive 10-year terms. To maintain protection, the owner must file a renewal application within 90 days before the expiration of each term. Once the renewal application is filed, the trademark remains effective until the Registrar issues a final decision. Renewals must comply with the procedures outlined in the relevant Ministerial Regulations.

    Are there faster options for trademark registration in Thailand?

    Yes. The Thai Department of Intellectual Property (DIP) offers fast-track examination options for trademark applications that meet specific criteria, such as:

    • A limited number of goods or services
    • Clear and standard descriptions
    • No amendments during examination

    Eligible applications may receive examination results faster than the normal process.
