European Patent Convention (EPC 1973)

Rule 88 128 Correction of errors in documents filed with the European Patent Office

Art. 78, 88, 91 R. 51

Linguistic errors, errors of transcription and mistakes in any document filed with the European Patent Office may be corrected on request. However, if the request for such correction concerns a description, claims or drawings, the correction must be obvious in the sense that it is immediately evident that nothing else would have been intended than what is offered as the correction.
