The European Patent Convention

(2)

A European patent application shall be filed in one of the official languages or, if filed in any other language, translated into one of the official languages in accordance with the Implementing Regulations. Throughout the proceedings before the European Patent Office, such translation may be brought into conformity with the application as filed. If a required translation is not filed in due time, the application shall be deemed to be withdrawn. 

(4)

Natural or legal persons having their residence or principal place of business within a Contracting State having a language other than English, French or German as an official language, and nationals of that State who are resident abroad, may file documents which have to be filed within a time limit in an official language of that State. They shall, however, file a translation in an official language of the European Patent Office in accordance with the Implementing Regulations. If any document, other than those documents making up the European patent application, is not filed in the prescribed language, or if any required translation is not filed in due time, the document shall be deemed not to have been filed. 

(6)

Specifications of European patents shall be published in the language of the proceedings and shall include a translation of the claims in the other two official languages of the European Patent Office.
