Filing services

The EPO regularly conducts surveys to monitor user satisfaction with its products and services.

The input gathered from these surveys enables us to review the quality and efficiency of our internal processes and services.

The surveys are carried out on behalf of the EPO by a contractor. For the period 2018-2023, the contractor is BERENT Deutschland GmbH.


Our survey on filing services takes the form of a short web interview of less than five minutes in duration.

All users having made use of our filing services in the previous 12 months are invited by e-mail to complete the survey via a link.

The survey is anonymous and the EPO has no way of tracing answers to individual users.


The survey is normally carried out every second year.
