As explained in VIII, 1.1, all the documents making up a European application (i.e. those listed in II, 4.1) must be filed in one of the languages referred to in Art. 14(1) and (2). If the description and claims are not filed in one of these languages, a date of filing cannot be accorded (Art. 80(d), see also J 9/01, not published in OJ). This is particularly the case when the application is wrongly filed in an admissible non-EPO language (for instance in Italian by an applicant who is resident in Sweden and is not an Italian national).
