When different correspondence addresses are specified in multiple documents submitted with a patent application, the USPTO follows a specific priority order to determine which address to use. According to MPEP 601.03(b) , the priority order is as follows: Application Data Sheet (ADS) Application Transmittal Oath or Declaration (unless a more current power of attorney exists) Power of Attorney The MPEP states: “In the experience of the Office, the ADS is the most recently created document and tends to have the most current address.” Therefore, if you want to ensure a specific correspondence address is used, it’s best to include it in the Application Data Sheet.
