Registration Process

Like a lot of countries with well-developed patent laws, Cambodia uses the first-to-file system. That means the applicant with the earliest filing date will get the patent grant. If the applicant claims priority, they’ll get the patent grant if they have the earlier priority date.

The priority date refers to when you first made your patent application in another country. This period will start upon filing the first application date. Its validity will last for twelve months at the maximum.

The Department of Industrial Property of the Ministry of Industry, Mines, and Energy is responsible for granting patents. If you’re not from Cambodia, you need to get a local Cambodian agent to represent you. You need to submit the application using either English or Khmer.



Your application should have the following information and documents:

  • Formal request and application
  • Invention Description
  • Claims for seeking protection
  • Diagrams
  • Abstract
  • Power of Attorney
  • Foreign filing information

If you’re the inventor, your dossier should also contain a Statement of the Applicant’s Right. Otherwise, you need to put the name and address of the inventor. Include a statement that justifies why you should get the right for the patent.

Once claiming priority, the governing body will request you to submit any search or examination reports. These should relate to your application from outside the country. You also need to show a copy of the granted foreign patent.



When applying for a patent, you need to pay the filing fee. Once you get the patent grant, you’ll need to pay a validity maintenance fee.

As for utility models, you need to pay to file for it. Take note, before you get a grant or a refusal for the patent, you can convert it into a utility model application and vice versa. Take note, you can only convert your application once, so ensure that you make the best choice.
