What should I do if the Priority Mail Express® label is illegible?

If the Priority Mail Express® label on your patent application package becomes illegible, it’s crucial to take immediate action to protect your filing date. The MPEP 513 provides guidance on this situation:

“If the Priority Mail Express® mailing label is not placed on the papers to be filed but on the outside of a package, the person mailing the papers should ensure that the Priority Mail Express® mailing label number is placed on each paper filed.”

To address an illegible label:

  • Immediately contact the USPTO to report the issue
  • Provide any available evidence of the mailing (e.g., receipt, tracking information)
  • Submit a petition to the USPTO explaining the circumstances
  • Include any supporting documentation to prove the mailing date

It’s best to prevent this issue by clearly writing the Priority Mail Express® label number on each document in the package before mailing. This ensures that even if the label becomes illegible, the USPTO can still identify and date your submission correctly.
