Renewal fees in Sri Lanka must be paid by certain dates. In this section you will find a description of how these renewal due dates are calculated, both the very first renewal due date and all subsequent renewal due dates.
No annuities are due throughout the application process. The first annuity is paid 24 months after the grant date to the National Intellectual Property Office of Sri Lanka.
For example, if the grant date is 2022-01-20, then the first annuity must be paid by 2024-01-20.
After the first annuity has been paid, all subsequent annuities must be paid annually on the anniversary of the grant date. The due date should be the month and date corresponding to the grant date.
For example, if the grant date was on November 9, then all subsequent annuities will be due on November 9 each year.

Renewal fees must be paid in Sri Lanka regardless of whether the patent is granted or not. You can find the rules for calculating the renewal due dates above in the Due Dates section.
The renewal fee in Sri Lanka can be paid up to 12 months before the renewal due date. It is important to note that the renewal fee cannot be paid earlier than this. Any payments made before the opening of the payment window will result in the payment being rejected.
Yes, it is possible to renew a Sri Lankan patent after its renewal due date. If you fail to pay the renewal fee before the due date, a grace period of 6 months is given wherein the renewal fees can still be settled. When entering the grace period you will incur a surcharge fee to be settled along with the renewal fee. If you wish to maintain the patent, both the renewal fee and the surcharge fee will have to be settled.\n\n\u200dFor example, if a patent has a renewal due date of 2021-05-31 and the due date is missed, the patent will enter the grace period from 2021-06-01. After this point both the renewal fee and the surcharge fee will need to be settled by 2021-11-30. Failure to pay these fees before the surcharge due date will result in the patent lapsing.

A patent will stay in force for 20 years in Sri Lanka from the filing date if successfully renewed in accordance with the rules described above. If the patent is not renewed, it will lapse by the end of the grace period measured from the latest renewal due date.
