Patent renewal fees in Vietnam: costs, due dates and grace period
You pay patent renewals in Vietnam to the NOIP, in VND, up to year 20. You pay nothing until the office grants your patent. Miss a due date and you get a 6-month grace period, with no surcharge.
What are the patent renewal due dates in Vietnam?
Vietnam counts annuities from the grant date, and the amount depends on which patent year you are entering. You pay nothing while the application is still pending.
The first renewal falls due three months after the grant date, payable to the NOIP.
For example, if the grant date is 2022-01-20, then the first three annuities must be paid by 2022-04-20.
Every later annuity falls due on the anniversary of the grant date, each year, until year 20.
For example, if the grant date was on November 9, then all subsequent annuities will be due on November 9 each year.

In Vietnam, you pay a fee per individual independent claim greater than one in addition to the base renewal fee.
For example, if you are to pay annuity 4, you will have to pay the base renewal fee plus the claim fee multiplied by the number of independent claims greater than one. For the purpose of this example, we will assume that the patent has 11 independent claims, which will result in the following calculation: Base Renewal Fee VND 1,000,000 + (Claim Fee VND 600,000 x 10) = VND 7,000,000.

Missed a patent renewal deadline in Vietnam?
A six-month grace period runs from the day after the due date. You can still pay the renewal fee, with no surcharge on top, and the patent continues without interruption. Once the grace period closes, the patent lapses.
If you miss a renewal due date of 20 January 2026, the patent enters the grace period on 21 January 2026. Settle the renewal fee by 20 July 2026 to keep the patent in force.

1. What do I pay while the application is pending?
Nothing. You pay no annuities in Vietnam while your application is pending. Payments start once the office grants your patent.
2. When can I pay the renewal fee?
Whenever you like. In Vietnam, you can settle renewal fees at any time and pay several annuities together in one go.
3. Can I renew a patent after missing a due date?
Yes. You get a 6-month grace period, starting the day after you miss the due date, and Vietnam adds no surcharge. Pay the renewal fee inside that window and your patent stays in force. Miss the window too and the patent lapses.
4. How long does a patent last?
Up to 20 years from the filing date, as long as you pay every annuity on time. Stop paying and it lapses at the end of the grace period that follows the last due date.
