J 0007/80 (Correction of mistakes; Languages) du 11.03.1981

I. If the wrong applicant is named in an application and the wrong applicant and the correct applicant are both companies forming part of the same group of companies then the mistake may be corrected under Rule 88 EPC, if there is sufficient evidence to support the request for correction.

II. Where documents making up an application are partly in an official language of the European Patent Office and partly in another language which is an official language of a Contracting State, then, for the purposes of deciding whether the application complies with Article 14(1) or (2) EPC, in accordance with Article 80(d) EPC, the significant language is that used for the description and claims. Other documents making up the application should normally be corrected by translation into that language.
