The application system in Brunei Darussalam operates on a ‘first-to-file’ basis; that is, the first person to apply will have priority over others for the same invention.

The key feature of the patent system in Brunei Darussalam is that it is a ‘self-assessing’ system whereby the applicants decide how to proceed and when.

The patent system is ‘formality-based’ and substantive examination work is outsourced to The Danish Patent and Trademark Office (DKPTO).
