7.10. Minutes of oral proceedings (Rule 124 EPC)
According to R. 124(3) EPC, the minutes shall be authenticated by the employee responsible for drawing them up and by the employee who conducted the oral proceedings or taking of evidence, either by signature or by any other appropriate means.
In case T 2076/11 the minutes were signed by a director rather than by the chairman who had presided over the oral proceedings before the opposition division. This was a substantial procedural violation.
