10.2.2 Refund of the further search fee 

If an applicant has paid a further search fee following a communication from the search division under Rule 64(2) but the examining division finds, on request, that the communication was not justified, the further search fee will be refunded. The same principle applies if the applicant has paid a search fee on the basis of an invitation by the examining division under Rule 164(2) (see C‑III, 3.1). In such cases, the examining division will, on request, review the justification for charging the search fee in its invitation under Rule 164(2) (see C‑III, 3.4).
