An applicant may also appoint an agent to represent him
specifically before the EPO in its capacity as SISA. Moreover, the agent appointed for the international phase - and thus including for the procedure before the SISA - may appoint a sub-agent to represent the applicant specifically before the EPO as SISA. All communications issued by the EPO as SISA are sent to the agent specifically appointed for the procedure before the EPO as SISA. An agent specifically appointed to act before the EPO as SISA must be entitled to practise before the EPO (see
point 97).
