Patent renewal fees in Bangladesh: costs, due dates and grace period
You pay patent renewals in Bangladesh to the DPDT, in BDT, up to year 20. The schedule starts at your fourth priority-date anniversary, granted or not. Miss a due date and you get a 3-month grace period, with a surcharge on top.
What are the patent renewal due dates in Bangladesh?
Bangladesh counts annuities from the priority date, and the amount depends on which patent year you are entering. A due date can arrive while the application is still pending.
The first renewal falls due at your fourth priority-date anniversary, payable to the DPDT.
For example, if the priority date is 2020-02-01, the first renewal will be due by 2024-02-01.
Every later annuity falls due on the anniversary of the priority date, each year, until year 20.
For example, if the priority date was on September 9, then all subsequent annuities will be due on September 9 each year.

Missed a patent renewal deadline in Bangladesh?
A three-month grace period runs from the day after the due date. You can still pay the renewal fee with a 1725 BDT 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 10 February 2026, the patent enters the grace period on 11 February 2026. Settle the renewal fee and the surcharge by 10 May 2026 to keep the patent in force.

1. What do I pay while the application is pending?
The same annuities you pay after grant. Bangladesh starts the schedule at your fourth priority-date anniversary, and it runs whether or not the office has granted your patent by then.
2. When can I pay the renewal fee?
Up to 3 months before the due date, and no earlier. Send it earlier and the office rejects the payment.
3. Can I renew a patent after missing a due date?
Yes. You get a 3-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 is a flat 1725 BDT. 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.
