How to Renew a Patent in Thailand?

While a patent is in the pending application stage, no renewal fees are due. Once a patent is granted in Thailand, you are obliged to pay a recurring renewal fee to the Department of Industrial Property (DIP) of Thailand to maintain the patent.The first renewal fee will be due annually starting from the fourth anniversary of the patent’s filing date (Year 5) upon the grant of the patent.

For example, if the filing date of a patent is 2015-01-15, and the grant date of the patent is 2018-12-15, you will only have to settle the first renewal fee on the fourth anniversary (Year 5) of the patent’s filing date on 2019-01-15. The next annuity will be due on 2020-01-5 (from the anniversary of filing date). Years 1, 2, 3, and 4 are exempted from the payment of renewal fees.

In the event that the patent is granted more than five years after the date of filing, you will have to settle the renewal fees within 2 months from the grant of the patent. 

For example, if the filing date of a patent is 2015-01-15 with the fourth anniversary of the filing date on 2019-01-15, and the grant date of the patent is 2019-12-15, you will have to settle the first renewal fee for Year 5 within 2 months from the grant of the patent on 2020-02-15. The next annuity for Year 6 will be due on 2020-01-15 (on the anniversary of filing date). Years 1, 2, 3, and 4 are exempted from the payment of renewal fees. The next annuity will be due for renewal on 2021-01-15.

Thailand Patent Renewal Fees FAQ

When is the first patent renewal fee due in Thailand?
keyboard arrow down

The first renewal fee is paid after they have granted the patent in Thailand. The first renewal of a granted patent is due on the fourth anniversary of the patent’s filing date. The renewal fee is intended to maintain the patent in force for the upcoming 5th year. 

For example, if the filing date of a patent is 2015.01.15, and the grant date of the patent is 2018.12.15, you will only have to settle the first renewal fee on the fourth anniversary (Year 5) of the patent’s filing date on 2019.01.15. The next annuity will be due on 2020.01.15 (from the anniversary of filing date). Years 1, 2, 3 and 4 are exempted from the payment of renewal fees.

keyboard arrow down

The renewal fees can be paid anytime before the payment due date.

Can I renew a patent after I miss a renewal deadline?
keyboard arrow down

Yes, it is possible to renew a patent in Thailand after its deadline. There is a 6-month grace period given, whereby the renewal fees can still be settled. When entering this grace period, there is no penalty fee for the first 2 months. However, for the next 4 months you will incur a penalty fee of 30% in addition to the regular annual renewal fee for the corresponding year. Failure to pay this fee during the grace period will result in the patent lapsing.

Do I need assistance from the local council?
