Oral proceedings may take place either at the instance of the UPP Division, if deemed expedient, or at the request of any party to the proceedings (Rule 21(1) UPR).
However, oral proceedings in the procedure concerning the request for unitary effect can only be held at the request of the proprietor if the UPP Division considers it expedient (Rule 21(2) UPR). In this context, procedures for re‑establishment of rights are not considered part of the procedure concerning the request for unitary effect.
Oral proceedings before the UPP Division are not open to the public (Rule 21(3) UPR).
