Patent Law FAQ

The MPEP provides guidance on what constitutes a valid mailing address for inventors in patent applications. According to MPEP 602.08(a):

“The inventor’s mailing address means that address at which he or she customarily receives his or her mail, even if it is not the main mailing address of the inventor. Either the inventor’s home or business address is acceptable as the mailing address. A post office box is also acceptable.”

The mailing address should include the ZIP Code designation. It’s important to note that the address of an attorney with instructions to forward communications is not sufficient, as the purpose is to enable direct communication between the USPTO and the inventor if necessary.
