If the Review Panel finds that a protest was entirely justified, the additional examination fees and the protest fee will be refunded.[Rule 68.3(c); (e); ]
If it finds that the protest was justified only in part, the corresponding additional examination fees will be refunded, but not the protest fee (see GL/PCT‑EPO C‑V, 5.2).
