What is the difference between ‘Express Mail’ and ‘Priority Mail Express’?
As of July 28, 2013, the United States Postal Service (USPS) renamed ‘Express Mail’ to ‘Priority Mail Express’. According to MPEP 511:
“Effective July 28, 2013, the United States Postal Service (USPS) changed the name of ‘Express Mail’ to ‘Priority Mail Express.’ All characteristics of the ‘Priority Mail Express’ service are the same as those of the former ‘Express Mail’ service (although the mailing labels differ).”
This change is important for patent applicants to note, as the USPTO’s rules and procedures now refer to ‘Priority Mail Express’ instead of ‘Express Mail’. However, the service characteristics and benefits for patent filings remain the same. When using this service for USPTO correspondence, ensure you use the correct addresses as specified in 37 CFR 1.1 and avoid using the ‘Hold for Pickup’ option, as the USPTO does not pick up mail.
