What is the difference between a correspondence address and a fee address in USPTO filings?

In USPTO filings, the correspondence address and fee address serve different purposes:

• Correspondence Address: Where the USPTO sends all official communications regarding a patent application or patent.
• Fee Address: Where the USPTO sends maintenance fee reminders for granted patents.

The MPEP clarifies:

The correspondence address is the address associated with the Customer Number to which correspondence is directed. The fee address is the address associated with the Customer Number to which maintenance fee reminders are directed. (MPEP 403)

While these addresses can be the same, they don’t have to be. Applicants or patent owners might choose different addresses, for example, if a law firm handles prosecution but the company itself manages maintenance fees. Using a customer number allows for easy management of both addresses.
