You pay patent renewals in South Korea to the KIPO, in KRW, 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 a surcharge that starts at 3% and climbs to 18%.
South Korea 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 KIPO.
For example, if the grant date is 2022-01-20, then the first three annuities must be paid by 2022-04-20.
After the first three annuities, every later annuity falls due on the anniversary of the grant date, from three years after grant.
For example, if the grant date is 2022-01-20, then the fourth annuity must be paid by 2025-01-20.

In South Korea, you pay a fee per claim 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 claims. For the purpose of this example, we will assume that the patent has 11 claims, which will result in the following calculation: Base Renewal Fee KRW 40,000 + (Claim Fee KRW 22,000 x Number of claims 11) = KRW 282,000
The official fees are fixed. What your provider adds on top is not. Send your email and we'll show you what these renewals should really cost.
A six-month grace period runs from the day after the due date. You can still pay the renewal fee with a surcharge that starts at 3% and climbs to 18%, 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 and the surcharge by 20 July 2026 to keep the patent in force.

There are no annuities due in Albania before the patent is granted. Once the patent has been granted, annuities must be paid annually in accordance with the rules described above under the section Due Dates.
At present, the opening of the renewal payment window in Albania has not been officially specified. Consequently, we are unable to confirm the earliest date on which the renewal fee can be paid.
Yes, it is possible to renew an Albanian patent after its renewal due date. If you fail to pay the renewal fee before the due date, a grace period of 8 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.
For 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 2022-01-31. 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 Albania 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.
