Trademark Registration in Thailand
Thai trademark registration: search for conflicting marks, choose classes that match actual use, file with the Department of Intellectual Property and monitor the opposition period after publication.
Thailand follows a first-to-file system, so long use without filing may not be enough. This guide prepares the mark, goods/services list and owner before filing; registration by the Registrar is not assured.
Information for a scope review
| Topic | Starting information | Review question |
|---|---|---|
| Applicant and owner | Individual or entity and creators | Ownership and assignments |
| Subject matter | Mark specimen, drawings or specification | Scope of protection and novelty |
| Deadlines | Disclosure and foreign filing dates | Priority, opposition and renewal |
Choose classes and items that match use
Thailand uses the Nice Classification. List goods or services actually sold or planned soon. Overly broad items may need amendment; overly narrow ones may under-protect.
Distinctiveness
Descriptive words, geographical names and common terms are often refused. Invented or arbitrary marks fare better. Prepare a clear specimen and translations or transliterations of foreign words.
After filing: examination, publication and opposition
The Registrar may require amendments or refuse, with responses due within set periods. Accepted marks are published and third parties may oppose within 60 days; the registration fee is paid afterwards.
Term and renewal
Registration lasts 10 years from the filing date and is renewable for further 10-year periods. Track deadlines, keep evidence of use and record changes of owner or address.
Owner and documents
Identify the applicant individual or entity. Overseas applicants need a Thai agent and a power of attorney, which may require certification in the form the authority accepts.
Questions before preparing an application
- I have used my mark for years. Must I register?
- Not legally, but unregistered rights are much weaker and an earlier filer may obtain the mark. Registration makes enforcement clearer.
- How long does a registration last?
- 10 years from filing, renewable for further 10-year periods.
- How long is the opposition period?
- 60 days from publication.
- Does a Thai registration protect abroad?
- No. Rights are territorial; consider the Madrid system or national filings.
- Is a pre-filing search required?
- No, but it reduces the risk of refusal or opposition after fees are paid.
- How can I obtain the service charges?
- Send the details for scope review and request a written quotation. Department of Intellectual Property fees are shown separately at the published rates.
