The EPO has no interpreters of its own but uses external services, which is costly and involves considerable organisation. As laid down in Rule 4(5) EPC, the cost of interpreters is borne by the EPO.
Every year, around 750 interpreting days are cancelled at short notice. In opposition proceedings, this can happen for various reasons, e.g.
- the oral proceedings are cancelled due to a withdrawal of the application, the opposition, or the request for oral proceedings
- the oral proceedings are postponed due to late submissions
- the party who requested interpreting does not attend the oral proceedings.
