Trademark Registration Checklist for Thailand
Complete document checklist for registering a trademark with Thailand's Department of Intellectual Property (DIP).
Document Checklist
Conduct trademark search on DIP database (ipthailand.go.th)
Search for identical and similar marks in your class of goods/services. Professional search recommended.
Trademark specimen (clear image of the mark)
Provide a high-resolution image of the trademark. For word marks, standard characters are acceptable. For design marks, provide the exact design.
Completed application form (Kor. 01)
Available from DIP or downloadable from ipthailand.go.th. Must be in Thai.
Power of attorney (if filing through an agent)
Must be signed by the applicant. No notarization required for Thai agents, but foreign applicants should have it notarized.
Classification of goods/services under Nice Classification
Identify the correct class(es) for your goods/services. Filing fee is THB 1,000 per class.
Payment of filing fee (THB 1,000 per class)
Payable at DIP or via bank transfer. Registration fee of THB 600 per class is due after approval.
Company registration documents or applicant ID
Thai company: company certificate and director ID. Foreign company: certificate of incorporation. Individual: passport or Thai ID.
Priority claim documents (if claiming convention priority)
If claiming priority from a foreign application, provide certified copy of the earlier application within 3 months.
Common Mistakes to Avoid
Filing a generic or descriptive mark — DIP will refuse marks that describe the product/service.
Not searching for existing marks before filing — identical or similar marks will be refused.
Wrong Nice Classification — filing in the wrong class means no protection for your actual goods/services.
Not responding to office actions within 60 days — the application will automatically lapse.
Assuming a company name registration equals trademark protection — they are separate legal concepts.
Helpful Tips
Thailand uses a first-to-file system — file early to secure your rights.
Consider engaging a Thai trademark attorney — they handle DIP communications and office action responses.
File in English and Thai if your mark uses English text — this provides broader protection.
Monitor the Trademark Gazette for similar marks being published — you have 60 days to oppose.
Register your trademark with Thai Customs to prevent counterfeit imports.
