Normally, the documents which are indicated in the international preliminary examination report as forming the basis for that report will also form the basis for the substantive examination in the EPO as an elected Office in the European phase. New documents (claims, description, drawings) submitted during the international preliminary examination and replacing the earlier filed documents will be attached to the international preliminary examination report. If the documents attached to the international preliminary examination report are in a language other than the language of the proceedings of the European application in the European phase, the applicant must be requested to file the documents in the language of the proceedings within a fixed period.
The applicant may also request that the examination be based on the documents in the international application as published or on amendments made on entry into the European phase. If the declarations of the applicant are unclear in this respect, the examiner will have to clarify the situation.
