How does the USPTO handle multiple correspondence addresses specified in a single document?

When multiple correspondence addresses are specified in a single document, the USPTO has a specific procedure for selecting which address to use. According to MPEP 601.03(b):

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

This means that if you provide multiple addresses, the USPTO will choose one, giving preference to a Customer Number address over a typed address. To avoid confusion, it’s best to clearly specify only one correspondence address in your patent application documents.
