2.2 Language for the purpose of the supplementary international search

For the purpose of the supplementary international search by the EPO as Supplementary International Searching Authority, the international application must be in one of its three official languages, i.e. English, French or German. Where the international application is filed in a different language, and no translation into any of these languages has been filed for the purpose of the proceedings before the International Searching Authority or for the purpose of international publication, a translation into one of these languages must be filed with the IB together with the request for supplementary international search.
