The European Patent Office (EPO) has announced a revised
schedule of official fees, set to take effect from 1 April 2026.
This update follows a decision by the Administrative Council on 11
December 2025 (CA/D 9/25) and represents a return to biennial
inflation-based adjustments.
The adjustments generally reflect an average increase of 5%
across most procedural stages. While many core fees will rise, the
EPO has opted to maintain current rates for specific filing and
contentious proceedings to manage the burden on applicants at early
and late stages.
The following table outlines the most common procedural fees
affected by the 5% adjustment:
