Patent registration services in Thailand

For patents, Thailand follows a first-to-file system. If you fail to register for a patent and someone else invents a similar or identical invention and obtains a patent for it, you might not be the owner of your intellectual property anymore. This is why it is important to obtain a patent as soon as possible. To register a patent in Thailand, the applicant can file an application online through the Department of Intellectual Property (DIP).

Types of Patents

Types of Patents in Thailand

There are different types of patents in Thailand, which include utility patent, design patent, and invention patent. You must follow these requirements before obtaining a patent.

The development/invention is patentable topic: Businesses wish to get various inventions patented but it is important to note that not everything can be patented. Patentable inventions include toys, machines, apparatuses, clinical gadgets, drug drugs, new assembling measures or mechanical techniques, programming, business strategies, organic material.

Novelty: If what you plan to patent is already available in the market, it is not eligible for a patent. Every single invention needs to be completely new in the public domain.

Utility: Regardless of the invention, if it is not practical enough to be used by the public or the industry, it will fail the utility factor.

There are various inventions that are not qualified for a patent, and these include numerical calculations or models, mental ideas or cycles, imaginative manifestations, plans, standards or speculations.

There are three types of patents:

  • Invention Patent: This requires that the invention be new, non-obvious, and capable of industrial application. The main point that distinguishes it from other types of patents is the ‘non-obvious’ factor.

Patents for invention can be filed in Thailand through two systems:

A national application (first filing in Thailand or within 12 months of a priority application filed in another country); or an application under the Patent Cooperation Treaty (PCT) system.

  • Design Patent: With this patent, you can protect the style and design sense of your invention. The patent report contains pictures and illustrations of your design and lacks words. Due to the lack of words, design patents are difficult to find.
  • Petty Patent: These types patents are for new inventions which could otherwise qualify for an invention patent but lack a strong, technical innovative step.

How to register a Patent in Thailand?

Step 1


Before filing an application, searching for already registered patents is always important. If you do not conduct a thorough search, you might not know if your invention is already patented or not. You can also understand the reasons of patent applications getting rejected. It is recommended to use a patent search service by an attorney or agent if you are inexperienced.

Step 1

Step 2


To file for a patent application in Thailand, the application and all of its content have to be in Thai language. If the application is filed in any other language other than Thai, then a translation must be provided along with the application. If the application is missing any information that is required by the patent office, the office will send a notice to the applicant to complete the application. If all the information is not provided on time, the application will be abandoned. The applicant is given 90 days to submit everything and if it exceeds that, additional charges have to be paid.

The application must contain:

  • The application fees;
  • Specifications and details of the patent;
  • Drawings (when necessary, for example a design);
  • Priority document (if applicable);
  • Power of Attorney;
  • Proof of application payment fee;
  • Priority claim (if applicable).

Step 3


After the application is recorded, the candidate needs to demand for assessment. The application goes through formal and meaningful assessment where the examiner takes a look at the application for archives, exactness, and culmination. Identical and similar patents are also checked.

In case there is any issue with the application or if the examiner needs extra documentation, a notification is given to the candidate which must be responded to in due time. Neglecting to react will leave the application abandoned.

The substantive examination takes place after the publication. (When requested)
