In T 917/95 the board held that a patentee who, in inter partes proceedings, filed a new claim but no amended description prior to the oral proceedings before the board of appeal and who failed to attend the oral proceedings could not rely on the board's postponing its ruling simply to permit amendment of the description, even if the new claim was grantable (see also T 725/00, T 109/02, T 181/02, T 776/05, T 651/08, T 2294/08; however see also T 985/11). In T 1810/06 the board extended this finding of T 917/95 to an ex parte case.
