Trademark registration in Thailand
A brand name, logo or sound used in trade gains statutory rights in Thailand once registered with the Department of Intellectual Property. We check for conflicts, frame the class list and prepare the filing; acceptance is decided by the Registrar.

The statutory steps
- Step 1
Clearance search
Search the DIP trademark database for similar words, devices and pronunciations in the classes you actually trade in, to judge the risk of confusion before filing.
- Step 2
Classes and specification
Thailand uses the international Nice Classification of 45 classes. Describe goods and services as actually sold: an over-broad list may draw an objection, a narrow one may leave gaps.
- Step 3
File the application
File online or at the DIP. Applicants without a Thai domicile must appoint a local agent; a power of attorney signed abroad may need legalisation as the DIP requires.
- Step 4
Examination and publication
The Registrar examines distinctiveness and conflicts. Office actions must be answered by the deadline stated. Accepted marks are published and third parties may oppose within 60 days of publication.
- Step 5
Registration fee
If there is no opposition, or it fails, the registration fee must be paid within the set period. Registration lasts 10 years from the filing date.
Marks that often run into trouble
- Plain descriptive words for the goods, or geographic names, which may lack distinctiveness.
- Words or devices close to an earlier mark in the same or related classes.
- State emblems, the national flag or names of government agencies, which the Act prohibits.
- Assuming a Thai filing protects abroad — rights are territorial.
Official fees are charged per listed item of goods or services; see the current DIP fee schedule. Our service fee is given separately in a written quotation.
Frequently asked questions
How long does protection last?
Ten years from the filing date, renewable for further 10-year terms. Renewal is filed within 90 days before expiry, or within the statutory grace period after expiry with a surcharge.
Does a Thai registration protect me abroad?
No. Rights are territorial. File in each country, or designate countries through the Madrid Protocol, to which Thailand is a party; each country still examines the mark.
Is a search compulsory?
No, but it is advisable. A similar earlier mark in the same class can lead to refusal. A search reduces risk; it does not certify the result.
Can one application cover several classes?
Yes. Official fees depend on the number of listed items — check the DIP fee schedule for current rates.
What if the Registrar objects?
Respond or appeal within the period stated in the notice; missing it can mean the application is abandoned. Send us the notice as soon as you receive it.
How long does it take and what does it cost?
Timing depends on examination and any opposition, so we do not promise a fixed period. Our fee depends on the marks, classes and responses needed and is quoted after review. We do not guarantee registration and have no refund policy.
