Maintenance fees or renewal fees are fees paid to maintain a granted patent in force. Some patent laws require the payment of maintenance fees for pending patent applications. Not all patent laws require the payment of maintenance fees and different laws provide different regulations concerning not only the amount payable but also the regularity of the payments. In countries where maintenance fees are to be paid annually, they are sometimes called patent annuities.

Research is indicating that renewal fees can be used to improve the innovation incentives generated by patent rights.

International patent applications filed under the Patent Cooperation Treaty are not subject to the payment of maintenance fees. However, maintenance fees may fall due to designated/elected national and regional offices. If renewal fees have become due by the time the national phase starts, they must be paid before the expiration of the time limit applicable for entering the national phase.

In Canada, maintenance fees for a patent application, or a patent issued from the application, are due on each anniversary of the filing date of the application, beginning on the second anniversary. The amount due each year escalates during the life of the patent or patent application. If the maintenance fee is not paid (by the applicant or agent of record) by the due date with respect to a patent application, the application is deemed abandoned. The abandoned application may be reinstated within 12 months of the date of abandonment, by filing a request for reinstatement with payment of the maintenance fee that is due and the reinstatement fee. The maintenance fee for a patent may be paid within a one year grace period after the due date, with the payment of a late fee. If the required fee has not been paid when the grace period expires, the patent lapses.

No annuity (maintenance) fees need to be paid while applications are pending. Once granted of the patent maintenance fees are due based on the anniversary of application date. The unpaid fees while the patent was pending have to be paid on grant.

Renewal fees are payable to the European Patent Office in respect of pending European patent applications in respect of the third year from the date of filing. These fees are paid in advance of the year in which they are due (such that the renewal fee for the third year falls due two years from the date of filing) and fall due on the last day of the month containing the anniversary of the date of filing. Renewal fees may not be validly paid more than three months before they fall due, except for the third renewal fee which can be paid up to six months before its due date (in accordance with amended Rule 51(1) EPC in force since April 2018). If the payment of a renewal fee for a European patent application is not made in due time, the renewal fee may still be validly paid within 6 months of the due date, provided that the additional fee provided by is paid within the 6 months as well. For the calculation of the 6 month additional period, the so called de ultimo ad ultimo rule is applied by the EPO. For instance, if a renewal fee was due in February 2004, the additional fee fell due on August 31, 2004 (Tuesday), i. e. 6 months from the end of February 2004. The obligation to pay renewal fees terminates with the payment of the renewal fee due in respect of the year in which the mention of the grant of the European patent is published. Subsequently, renewal fees are payable to the national offices of the EPC Contracting States in which the European patent is brought into effect. Each Contracting State then pays the European Patent Organisation a proportion of each renewal fee received for a European patent in that State.

In a widely criticised move the Italian Parliament approved the cancellation of all maintenance fees due for Italian patents (including European patents validated in Italy), utility models and designs, as from January 1, 2006. Although the fees were reintroduced on January 2, 2007, the actual amounts of the fees were not announced until April 6, 2007. Consequently, for any fees that fell due between January 2, 2007, and April 30, 2007, the time limit for paying these was extended to June 30, 2007. Some, including Roland Grossenbacher, then chairman of the Administrative Council of the European Patent Organisation, considered that the abolishment of annuity fees in Italy was an error, because, if annuities were abolished, "all patents would remain in force up to the 20th year."

Patent maintenance fees are due in Russia every year starting with the third year after the application date. The maintenance fee increases from 1,700 roubles (22.43 US$) on the third year to 16,200 roubles ($213.73) on the twentieth year. Up to 5 fold discounts are available for individual inventors, small and non profit businesses, and those, who are willing to license their patents under nominal cost and non discriminatory terms. Russian law firms charge substantially larger "payment processing fees" than what Rospatent charges as patent maintenance fees. However, since June 23, 2022 most foreign patent owners have been unable to make patent maintenance payments in Russia, and their patents have expired. This is because Rospatent requires all payments to be processed via Central Bank of Russia, and this bank has been a subject of sanctions imposed by the United States and its allies.

The United Kingdom does not require renewal fees to be paid in respect of pending applications but a granted patent must be renewed on the 4th anniversary of the filing date and every year after that. Historically, and in contrast to most other European countries and the European Patent Office, the law in the United Kingdom required that renewal fees be paid on the anniversary of the filing date rather than on the last day of the month. Following amendments made by the Patents Act 2004, The Patents (Amendment) Rules 2005, which came into effect on 1 October 2005, ensured that any period prescribed for payment of a renewal fee does not expire until the end of the month in which the renewal date falls.
