1.10 Filing of correspondence by Priority Mail Express ®.
- (a)
- (1) Any correspondence received by the U.S. Patent and Trademark Office (USPTO) that was delivered by the Priority Mail Express ® Post Office to Addressee service of the United States Postal Service (USPS) will be considered filed with the USPTO on the date of deposit with the USPS.
- (2) The date of deposit with USPS is shown by the “date accepted” on the Priority Mail Express ® label or other official USPS notation. If the USPS deposit date cannot be determined, the correspondence will be accorded the USPTO receipt date as the filing date. See § 1.6(a) .
- (b) Correspondence should be deposited directly with an employee of the USPS to ensure that the person depositing the correspondence receives a legible copy of the Priority Mail Express ® mailing label with the “date accepted” clearly marked. Persons dealing indirectly with the employees of the USPS (such as by deposit in a Priority Mail Express ® drop box) do so at the risk of not receiving a copy of the Priority Mail Express ® mailing label with the desired “date accepted” clearly marked. The paper(s) or fee(s) that constitute the correspondence should also include the Priority Mail Express ® mailing label number thereon. See paragraphs (c), (d) and (e) of this section.
- (c) Any person filing correspondence under this
section that was received by the Office and delivered by the
Priority Mail Express
® Post Office to
Addressee service of the USPS, who can show that there is a
discrepancy between the filing date accorded by the Office to the
correspondence and the date of deposit as shown by the “date
accepted” on the Priority Mail Express
®
mailing label or other official USPS notation, may petition the
Director to accord the correspondence a filing date as of the “date
accepted” on the Priority Mail Express
®
mailing label or other official USPS notation, provided that:
- (1) The petition is filed promptly after the person becomes aware that the Office has accorded, or will accord, a filing date other than the USPS deposit date;
- (2) The number of the Priority Mail Express ® mailing label was placed on the paper(s) or fee(s) that constitute the correspondence prior to the original mailing by Priority Mail Express ®; and
- (3) The petition includes a true copy of the Priority Mail Express ® mailing label showing the “date accepted,” and of any other official notation by the USPS relied upon to show the date of deposit.
- (d) Any person filing correspondence under this
section that was received by the Office and delivered by the
Priority Mail Express
® Post Office to
Addressee service of the USPS, who can show that the “date
accepted” on the Priority Mail Express
®
mailing label or other official notation entered by the USPS was
incorrectly entered or omitted by the USPS, may petition the
Director to accord the correspondence a filing date as of the date
the correspondence is shown to have been deposited with the USPS,
provided that:
- (1) The petition is filed promptly after the person becomes aware that the Office has accorded, or will accord, a filing date based upon an incorrect entry by the USPS;
- (2) The number of the Priority Mail Express ® mailing label was placed on the paper(s) or fee(s) that constitute the correspondence prior to the original mailing by Priority Mail Express ®; and
- (3) The petition includes a showing which establishes, to the satisfaction of the Director, that the requested filing date was the date the correspondence was deposited in the Priority Mail Express ® Post Office to Addressee service prior to the last scheduled pickup for that day. Any showing pursuant to this paragraph must be corroborated by evidence from the USPS or that came into being after deposit and within one business day of the deposit of the correspondence in the Priority Mail Express ® Post Office to Addressee service of the USPS.
- (e) Any person mailing correspondence addressed as set
out in §
1.1(a)

service of the USPS but not received by the Office, may petition
the Director to consider such correspondence filed in the Office on
the USPS deposit date, provided that:
- (1) The petition is filed promptly after the person becomes aware that the Office has no evidence of receipt of the correspondence;
- (2) The number of the Priority Mail Express ® mailing label was placed on the paper(s) or fee(s) that constitute the correspondence prior to the original mailing by Priority Mail Express ®;
- (3) The petition includes a copy of the originally deposited paper(s) or fee(s) that constitute the correspondence showing the number of the Priority Mail Express ® mailing label thereon, a copy of any returned postcard receipt, a copy of the Priority Mail Express ® mailing label showing the “date accepted,” a copy of any other official notation by the USPS relied upon to show the date of deposit, and, if the requested filing date is a date other than the “date accepted” on the Priority Mail Express ® mailing label or other official notation entered by the USPS, a showing pursuant to paragraph (d)(3) of this section that the requested filing date was the date the correspondence was deposited in the Priority Mail Express ® Post Office to Addressee service prior to the last scheduled pickup for that day; and
- (4) The petition includes a statement which establishes, to the satisfaction of the Director, the original deposit of the correspondence and that the copies of the correspondence, the copy of the Priority Mail Express ® mailing label, the copy of any returned postcard receipt, and any official notation entered by the USPS are true copies of the originally mailed correspondence, original Priority Mail Express ® mailing label, returned postcard receipt, and official notation entered by the USPS.
- (f) The Office may require additional evidence to determine if the correspondence was deposited as Priority Mail Express ® with the USPS on the date in question.

- (h) Any person who attempts to mail correspondence
addressed as set out in §
1.1(a)

Office with sufficient postage utilizing the Priority Mail
Express
® Post Office to Addressee
