What is the correspondence address in a patent application?

The correspondence address in a patent application is the address where the United States Patent and Trademark Office (USPTO) will send all official communications regarding the application. According to 37 CFR 1.33(a):

“When filing an application, a correspondence address must be set forth in either an application data sheet (§ 1.76), or elsewhere, in a clearly identifiable manner, in any paper submitted with an application filing.”

This address is crucial for ensuring that applicants receive all necessary information and notifications about their patent application.
