Who can sign amendments and papers on behalf of patent owners in ex parte reexamination proceedings?

In ex parte reexamination proceedings, the MPEP specifies who can sign amendments and other papers on behalf of patent owners:

“Amendments and other papers filed on behalf of patent owners must be signed by the patent owners, or the registered attorney or agent of record in the patent file, or any registered attorney or agent acting in a representative capacity under 37 CFR 1.34(a).”

This means that the following individuals can sign documents:
