1.2 Language of the proceedings

The official language of the EPO (chosen fromEnglish, French or German) in which the application is filed, or into which it is subsequently translated, constitutes the "language of the proceedings". Amendments to a European patent application or European patent must be filed in the language of the proceedings. This language is also used by the EPO in written proceedings. (As regards documents which are not filed in the correct language, see A‑VII, 4 below).
