111.02 Requirements for Priority Mail Express®
As 37 CFR § 2.198(b) provides, prior to the original mailing, the Priority Mail Express® mailing label number should be placed on correspondence filed thereunder. The number of the mailing label should be placed on each separate submission and each fee transmitted, either directly on the document or on a separate paper firmly and securely attached to the document.
A party that wishes to send mail to the Board by the Priority Mail Express® service of the U.S. Postal Service should be careful to use the "Priority Mail Express® Post Office to Addressee" service, rather than the Priority Mail Express® "Hold for Pickup" service which delivers the mail Post Office to Post Office .
