Formalities services

Every year the EPO carries out user satisfaction surveys on its search, examination and opposition services, including formalities services.

We run these surveys so that we can

  • measure user satisfaction with our search, examination and opposition services
  • obtain input to enable us to review the quality and efficiency of our internal processes in these areas

The surveys are carried out on behalf of the EPO by a contractor. For the period 2018 - 2020, the contractor is BERENT Deutschland GmbH.


This survey takes the form of an online web-form. It relates to our formalities services.

The EPO creates a list of potential survey respondents from the names of users who have contacted the EPO in the previous 12 months and forwards this list to the survey company.

Respondents are asked about formalities services in general, as well as about specific aspects relating to their work.

Once the survey has been completed the contractor reports the results to the EPO.

Data is grouped and analysed on a purely statistical basis. Aggregated results are reported to senior EPO management and to the directors concerned.


The survey on formalities services is carried out annually.
