Patent renewal fees in Laos: costs, due dates and grace period
You pay patent renewals in Laos to the Department of Intellectual Property, in LAK, 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 50% surcharge on top.
What are the patent renewal due dates in Laos?
Laos counts annuities from the filing 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 60 days after the grant date, payable to the Department of Intellectual Property.
For example, if the grant date is 2022-01-20, then the first renewal must be paid by 2022-03-21.
Every later annuity falls due on the anniversary of the filing date, each year, until year 20.
For example, if the filing date was on September 9, then all subsequent annuities will be due on September 9 each year.
Laos is an EPO validation state, not an EPC member. A European patent covers Laos only if you requested validation and paid the validation fee while the application was pending; after grant the Department of Intellectual Property takes over, under the same rules as a national patent.

Missed a patent renewal deadline in Laos?
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?
Nothing. You pay no annuities in Laos while your application is pending. Payments start once the office grants your patent.
2. When can I pay the renewal fee?
Up to 6 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. 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 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.
