MPEP 500 - Receipt and Handling of Mail and Papers (3)

If you cannot file your patent application electronically or by Priority Mail Express® due to an emergency, consider the following options:

  1. Use first-class mail with a Certificate of Mailing under 37 CFR 1.8
  2. Hand-deliver the application to the USPTO, if possible
  3. If the emergency is a designated postal service interruption, follow the specific instructions provided by the USPTO on their website or in the Official Gazette

Remember that the provisions for postal emergencies only apply to actual USPS service interruptions, not other circumstances like computer failures or office inaccessibility.

As stated in MPEP 511: “Applicants are cautioned that the provisions of 35 U.S.C. 21(a) and 37 CFR 1.10(g) to (i) only apply to postal interruptions and emergencies.

In the event of a postal interruption or emergency:

  • An announcement will be placed on the USPTO website at www.uspto.gov
  • A notice will be published in the Official Gazette
