What happens to a power of attorney during an interference or derivation proceeding?

During an interference or derivation proceeding, any changes to the power of attorney must be forwarded to a specific board for review. As stated in MPEP 402.05: While an application is involved in an interference or derivation proceeding, any power of attorney or revocation of power of attorney should be forwarded to the Patent Trial and Appeal Board for consideration. This ensures that the appropriate authority handles changes in representation during these specialized proceedings.
