What type of issues can I report via this channel?

Individuals and organisations outside the EPO can report suspected fraud, corruption, abuse or other wrongdoing committed against the interests of the EPO or by a staff member or a person affiliated with the EPO.

Please assess critically if the issue you want to report falls into this category, bearing in mind that there are other contact channels for other types of communications (General comments, Formal complaint / feedback, Ombuds Office). Further guidance can be found in the Red Line sections of the Handbook for workplace ethics at the EPO.
