Documents making up the European patent application can only be filed in the wrong language on the occasion of its amendment, since the application can originally be filed in any language (see
A‑VII, 1.1). In such a case, as well as if any other document is not filed in the prescribed language or any required translation is not filed in due time, the document is deemed not to have been filed. The person who has filed the document will be notified accordingly by the EPO.
