How does the USPTO handle multiple correspondence addresses?

When multiple correspondence addresses are provided, the USPTO has a specific process for selection. According to 37 CFR 1.33(a):

“If more than one correspondence address is specified, the Office will select one of the specified addresses for use as the correspondence address and, if given, may select the address associated with a Customer Number over a typed correspondence address.”

This means that the USPTO will choose one address for all official communications, with a preference for Customer Number addresses if provided. Applicants should be aware of this to ensure they provide the most appropriate address for correspondence.
