What is a customer number and how does it simplify patent correspondence?

A customer number is a unique identifier assigned by the USPTO to simplify patent correspondence. According to MPEP 403:

‘A customer number allows a patent applicant, patent owner, or assignee to designate a single correspondence address for all applications and patents associated with that customer number.’

Benefits of using a customer number include:

• Easier management of correspondence addresses for multiple applications
• Simplified process for changing the address or representative for all linked applications
• Improved efficiency in USPTO communications

To obtain a customer number, you need to file a request with the USPTO using the appropriate form.
