USS 2022-2023 survey results infographic

As part of its quality management system, the EPO carries out ongoing reviews of the quality of its services and the efficiency of its procedures.

To help us do this, we rely on the direct feedback we get from our users contacted by phone or by e-mail. 

The results from our surveys also help us to shape the content of our in-house training programmes and draw up our annual budget forecasts.


Results of the 2022/2023 user satisfaction surveys

The latest series of user satisfaction surveys, for the period 2022/2023, was conducted between September 2022 and April 2023. Thank you very much to all respondents to these surveys; we highly appreciate your feedback.


The EPO conducts regular surveys in the following areas:

search services

examination services, final actions and publication

opposition services

patent filings

online services (formerly known as epoline)

patent information services

customer services

filing services website

survey on electronic invoicing

Survey of clean and sustainable technologies

Because the target groups for most of these surveys are patent applicants and attorneys, it may be that some respondents are asked to participate in more than one exercise, although we are currently looking into ways of reducing the demands on individual participants.

We would like to take this opportunity to thank all participants for taking the time to respond to our requests for feedback.

This site area explains the purpose of each of the surveys, along with the methods used, the target groups involved, and how often they are carried out.

We also carry out one-off surveys on specific issues as required.
