For the second year in a row, the European Patent Office will increase its official fees as of 1 April 2023

The European Patent Office (EPO) has announced that the official fees charged for European patent applications will be increasing from 1 April 2023. More details of the fee increases can be found on the EPO website.

On average, the official fees will increase by about 5%.

In view of the EPO’s official fee increases, applicants may want to consider the timing for paying fees in relation to their applications to maximise any opportunities to pay lower official fees.

For example, it may be sensible to file a European regional phase application (based on an international (PCT) application) before 1 April 2023, so as to avoid the fee increase. Furthermore, maintenance/renewal fees for European patent applications can be paid up to 3 months in advance of their due date, except for the first fee (for the 3rd year) which can be paid up to 6 months in advance. Filing a divisional application before 1 April 2023 would also bring savings, as would requesting examination and paying designation fees ahead of the due date.
