What is a Customer Number and how is it used in patent applications?
A Customer Number is a USPTO-assigned number that can be used to:
- Designate the correspondence address for a patent application or patent
- Designate the fee address for a patent
- Submit a list of practitioners with power of attorney
According to MPEP 403: “A Customer Number may be used to designate the address associated with the Customer Number as the correspondence address of an application (or patent) or the fee address of a patent, and may also be used to submit a power of attorney in the application (or patent) to the registered practitioners associated with the Customer Number.”
Using a Customer Number simplifies making changes to correspondence addresses and practitioner information across multiple applications.
