How can I change the correspondence address for multiple patent applications?

Changing the correspondence address for multiple patent applications can be efficiently done using the USPTO’s Customer Number practice. Here’s how:

1. Obtain a customer number if you don’t already have one.
2. Associate your patent applications with the customer number.
3. Update the address linked to the customer number.

The MPEP explains:

A Customer Number may be used to: … (2) change the correspondence address, fee address, or list of practitioners of record for a plurality of applications or patents through a single request. (MPEP 403)

This process eliminates the need to file separate change of address forms for each application, saving time and reducing the risk of errors. To make changes, use the USPTO’s Electronic Filing System (EFS-Web) or file a written request with the USPTO.
