DPDT conducts formality examination and substantive examination of invention patent applications. The substantive examination starts automatically, and the applicant does not need to file a separate request for substantive examination. If the conditions for patent granted are met, the patent application will enter the public stage. If there is no objection within 4 months after publication, the patent application will be authorized.
It is protected for 5 years from the date of application, renewed every 5 years, and can be renewed twice, up to a maximum of 15 years.
