How does changing the correspondence address in a patent application affect a patent practitioner’s address in the USPTO roster?

Changing the correspondence address in a patent application does not affect a patent practitioner’s address in the USPTO roster of patent attorneys and agents. This is explicitly stated in 37 CFR 1.33(e):

A change of address filed in a patent application or patent does not change the address for a patent practitioner in the roster of patent attorneys and agents. See § 11.11 of this title.

This means that practitioners must separately update their contact information in the USPTO roster if they wish to change their official address on record with the USPTO. The change of correspondence address in a specific application or patent is independent of the practitioner’s address in the official roster.
