What is the correct address for correspondence in patent reexamination proceedings?

According to MPEP 2622, the correct address for all notices, official letters, and other communications for patent owners in reexamination proceedings is the correspondence address for the patent being reexamined. This is specified in 37 CFR 1.33(c), which states:

“All notices, official letters, and other communications for the patent owner or owners in a reexamination or supplemental examination proceeding will be directed to the correspondence address in the patent file.“

This ensures that all relevant communications are sent to the address on record for the patent undergoing reexamination.
