Patent renewal fees in Angola: costs, due dates and grace period
You pay patent renewals in Angola to the IAPI, in AOA, up to year 15. Nothing is due for the first two years; the schedule then runs from your filing date, granted or not. Miss a due date and you get a 6-month grace period, with a 50% surcharge on top.
What are the patent renewal due dates in Angola?
Angola counts annuities from the filing date, and the amount depends on which patent year you are entering. A due date can arrive while the application is still pending.
No annuity is due for years 1 and 2. The first payment is the year-3 annuity, due at your second filing anniversary, payable to the IAPI.
For example, if the filing date is 2020-02-01, the first payment falls due by 2022-02-01.
Every later annuity falls due on the anniversary of the filing date, each year, until year 15.
For example, if the filing date was on September 9, then all subsequent annuities will be due on September 9 each year.

Missed a patent renewal deadline in Angola?
A six-month grace period runs from the day after the due date. You can still pay the renewal fee with a 50% 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 15 March 2026, the patent enters the grace period on 16 March 2026. Settle the renewal fee and the surcharge by 15 September 2026 to keep the patent in force.

1. What do I pay while the application is pending?
The same annuities you pay after grant. Angola counts them from your filing date, so a due date can arrive before the office grants your patent.
2. When can I pay the renewal fee?
The patent office in Angola has not published an opening date for its payment window, so we cannot confirm the earliest date you can pay.
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. Pay the renewal fee plus a surcharge inside that window and your patent stays in force. The surcharge runs at 50% of the renewal fee. Miss the window too and the patent lapses.
4. How long does a patent last?
Up to 15 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.
