Patent renewal fees in Tajikistan: costs, due dates and grace period
Where you pay in Tajikistan depends on where you filed: filings made at the EAPO renew there, national filings at the NCPI. The patent runs up to year 20 either way. Miss a due date and you get a 6-month grace period, with a surcharge set by your fee tier.
What are the patent renewal due dates in Tajikistan?
Tajikistan is a contracting state of the Eurasian Patent Office (EAPO). An EAPO patent takes effect in Tajikistan once the EAPO grants it, and you pay its renewal fees directly to the EAPO, not to the NCPI. National patents follow their own rules.
Official patent renewal fees by year in Tajikistan
Official fees payable to the NCPI, by patent year, in TJS. These are the national route fees. A patent filed through the EAPO is renewed there instead, on its own fee schedule.

Missed a patent renewal deadline in Tajikistan?
A six-month grace period runs from the day after the due date. You can still pay the renewal fee with a surcharge set by your fee tier, 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?
It depends where you filed. At the EAPO, nothing until grant, and your first payment then covers what built up. Filed nationally, you pay any annuity that falls due while you wait.
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 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. Your fee tier sets the amount. 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.
