How to register a trademark in Thailand

  1. Search the DIP public trademark database for earlier conflicting marks.
  2. File the application in Thai with the DIP, online or on paper; foreign applicants file through a Thai agent under a power of attorney.
  3. The DIP registrar examines formalities and registrability, including conflicts with earlier marks; office actions must be answered within 60 days.
  4. Accepted applications are published for 60 days, during which third parties may oppose.
  5. If there is no opposition or it fails, pay the registration fee within 60 days of notification.
  6. The mark is registered and a registration certificate is issued.

Examination, publication and opposition

  • Examination: DIP registrars examine formalities and substance; no general official time frame was found. A First Action Fast Track service can give a first office action within about 6 months for applications meeting its conditions.
  • Opposition period: 60 days from publication (reduced from 90 days by the 2016 amendment); the applicant has 60 days to file a counter-statement

Protection, renewal and use

  • Term: 10 years from the registration date, renewable.
  • Late renewal: Renewal may be filed within 90 days before expiry, or within 6 months after expiry with a surcharge of 20% of the renewal fee
  • Use requirement: a registration can be challenged after 3 years of non-use.
  • Rights system: first to file.

Filing from abroad

  • Local agent: Foreign applicants must appoint a Thai agent, who acts as the address for service in Thailand.
  • Power of attorney: A power of attorney is required when filing through an agent; secondary sources state it must be notarised if signed abroad. Legalisation requirements were not verified.
  • Language: Thai

Madrid Protocol

Thailand is a member of the Madrid System (in force since 2017). You can designate it in an international application filed through your home office, or file a national application directly. A local firm can advise which route is cheaper for your classes and timeline.

Trademark classes

Nice Classification (45 classes); official fees are charged per item of goods/services up to five items in a class, then at a flat rate per class. One application can cover several classes. Not sure which classes you need? See all 45 classes or classes by business type.

How Thailand compares

Guides: registering in any country · costs by country · Madrid

Good to know in Thailand

  • Official fees depend on the number of goods/services items: up to five items in a class are charged per item, and more than five items are charged a flat per-class rate, so long specifications cost noticeably more.
  • Multi-class applications and sound marks became possible with the 2016 amendment to the Trademark Act.
  • The DIP offers a First Action Fast Track service that can give a first office action within about 6 months if strict conditions are met (for example, limited items using DIP-approved descriptions).
  • A registration can be cancelled after three consecutive years of non-use.
