1. Admissible languages on filing
The international application, i.e. the request, description, claim(s), drawing(s) and abstract, must be filed with the EPO as receiving Office in English, French or German.
An international application filed in another language will be transmitted to the IB to act as receiving Office instead of the EPO. This means that it is not possible to file an international application with the EPO as receiving Office in a language other than the three indicated in Art. 14 EPC for European patent applications not filed via the PCT route (Euro-direct applications).
