Trademark registration in Thailand runs through the Department of Intellectual Property (DIP) under the Trademark Act B.E. 2534. Thailand is a first-to-file country: rights go to whoever registers the mark first, not to whoever used it first in the market. A brand that trades here unregistered can watch someone else register its own name, and the Act even deems a registration effective from the date the application was filed, which makes the filing date the date that counts.
A registration lasts ten years, counted in practice from that filing date, and can be renewed for further ten year periods indefinitely. Word marks, logos, and combined marks are the common filings, and each application is examined for distinctiveness and for conflicts with earlier marks before it is published for opposition.
Registration protects one mark for the goods or services it is registered against, sorted into classes. It does not protect an invention or a creative work; those are the territory of patents and copyright, and an intellectual property lawyer can map which of the three a brand actually needs.
Official trademark fees under the Trademark Act
Fees from the schedule annexed to the Trademark Act B.E. 2534, as amended by Trademark Act (No. 3) B.E. 2559. Fees are per class of goods or services; firm fees for search, filing, and prosecution are separate and set by each firm.
| Item | Official fee |
|---|---|
| Application, 1 to 5 items of goods or services in a class | 1,000 baht per item |
| Application, over 5 items in a class | 9,000 baht per class, flat |
| Registration fee, 1 to 5 items in a class | 600 baht per item |
| Registration fee, over 5 items in a class | 5,400 baht per class, flat |
| Renewal, 1 to 5 items in a class | 2,000 baht per item |
| Renewal, over 5 items in a class | 18,000 baht per class, flat |
| Opposition against a published application | 2,000 baht per opposition |
| Recording an assignment or inheritance of a mark | 2,000 baht per application |

Note: How long does it take?
The DIP does not publish an official processing time, and any figure you see quoted is a market estimate rather than a government commitment. What is fixed by law is the shape of the process: examination, then publication with a sixty day opposition window, then payment of the registration fee. In practice the full run from filing to certificate is commonly a matter of many months, and an opposition extends it. A firm that searches the register before filing can tell you where your mark is likely to slow down.

Search before you file
The firm searches the register for identical and confusingly similar earlier marks and assesses distinctiveness. This is the cheapest point to learn that a mark needs adjusting; after filing, official fees are spent whatever the outcome.
File with the DIP
The application states the mark, the owner, and the goods or services by class. Foreign applicants act through a local agent or address for service in Thailand, so the filing itself is normally handled by the firm.
Examination
The registrar examines the mark for distinctiveness, prohibited elements, and conflicts with earlier registrations, and can order amendments. Responses to office actions carry their own deadlines, typically sixty days from receipt of an order.
Publication and the 60 day opposition window
An accepted application is published, and under Section 35 of the Trademark Act any person may oppose within sixty days of publication. If an opposition lands, the applicant has sixty days to file a counterstatement, and the registrar decides.
Pay the registration fee and receive the certificate
Once the application clears, the registration fee is paid and the certificate issues. The registration is deemed effective from the filing date and runs for ten years from it.
Renew every ten years
Renewal is filed in the three months before expiry. Miss that and the Act allows a late renewal within six months of expiry with a twenty percent surcharge; miss both and the registration is cancelled.
Thailand has been a member of the Madrid Protocol since November 7, 2017, so an international registration can designate Thailand instead of filing directly with the DIP. The designation is examined under the same Thai rules, and a local agent is still needed the moment the DIP raises an objection or a third party opposes. Which route costs less depends on how many countries the brand needs and how clean the mark is; a firm models both before filing.
For businesses building a presence here the trademark rarely travels alone. Registering the brand is a standard early step alongside company registration, and it is the foundation piece when a brand is licensed to others, which is why franchise work usually starts with the question of who owns the mark.
Registration is what makes enforcement practical. Counterfeiting a registered mark carries up to four years imprisonment or a fine up to 400,000 baht or both under Section 108 of the Trademark Act, and imitation up to two years or 200,000 baht under Section 109. Trademark disputes are heard by the Central Intellectual Property and International Trade Court, and a firm handling litigation and disputes will build the case on the registration certificate.
What registration does not do is rescue a weak mark. Generic and purely descriptive signs fail examination, a mark confusingly similar to an earlier registration draws a refusal or an opposition, and a registered mark left unused can be attacked for non-use. A lawyer can assess these risks against the register before any official fee is spent.
