Who handles power of attorney changes during interference or derivation proceedings?

During interference or derivation proceedings, power of attorney changes are handled by a specific entity within the USPTO. According to MPEP 402.08:

While an application is involved in an interference or derivation proceeding, any power of attorney of or revocation of power of attorney should be forwarded to the Patent Trial and Appeal Board for consideration.

This means that the Patent Trial and Appeal Board (PTAB) is responsible for considering and processing any changes to power of attorney during these special proceedings. This differs from the normal procedure for regular patent applications, where such changes would typically be handled by the Office of Patent Application Processing or the examining corps.
