On September 27, 2004, the USPTO published a Postal Interruption Notice stating that
37 CFR 1.10(i) (effective September 21, 2004) addresses interruptions or emergencies in USPS "Express Mail Post Office to Addressee" service that are designated by the Director. Correspondence covered by 37 CFR 1.10 (non-trademark correspondence) that would have been filed with the USPTO under 37 CFR 1.10 during this USPS service interruption, but which was not filed due to the USPS service interruption, should be filed promptly after the termination of the USPS service interruption with a petition in accordance with 37 CFR 1.10(i) using "Express Mail" service in accordance with 37 CFR 1.10. . . . As soon as the USPTO receives further information from the USPS as to when postal services in the affected areas will be resumed, the USPTO will post updated information regarding this situation on the USPTO Web site (http://ww.uspto.gov) and in the Official Gazette. Inquiries concerning this notice may be directed to Fred Silverberg by e-mail at email@example.com or by telephone at 703-305-8986 or 571-272-7719.
