    Procedure for Patent Registration in Vietnam

    To do patent registration in Vietnam, you must follow the steps listed below:

    1. Initial search

    Firstly, perform an initial search to find out if your innovation qualifies for patent protection and if any Vietnamese patents with a similar scope currently are present. This stage aids in evaluating the novelty and originality of your invention.

    2. Prepare your Patent application

    To do patent filing in Vietnam, you must first complete the application form given by the National Office of Intellectual Property (NOIP). You must present a detailed explanation of your invention, detailing all of its technical components as well as its uses and benefits.

    3. Application Submission 

    Send or deliver the filled-out application to the NOIP either physically or by mail. Make sure all required paperwork is enclosed, duly completed, and signed.

    4. Formality check 

    To ensure that all necessary documentation has been submitted and properly filled out, the NOIP will perform a formality check on your application. If errors are discovered, you will be informed and given a deadline to eliminate them.

    5. Publication

    Within 19 months, measured from the initial filing date, your patent application is going to be released in the IP Gazette after completing the formality assessment.

    6. Substantive examination request

    You have to ask for a substantive examination within 42 months of the filing date or priority date (whichever comes first).

    7. Examination result

    The NOIP shall publish an examination statement indicating if the innovation satisfies the criteria for patentability. The substantive examination result must be released by NOIP 18 months after the date of publication. If the outcome is positive, the patent must be awarded within one to two months. If not, the individual who applied for the patent has a period of three months (extended for a further three months) to reply to the refusal.

    8. Granting the Patent

    After a decision to issue a patent is officially produced, the patent right will become effective upon its entry into the Patent Register, provided the person submitting the application has paid the applicable patent cost, within one to three months of the notice of patent issuing.
