(a) It is desirable that all parts of the complete application be deposited in the Office together; otherwise, a letter must accompany each part, accurately and clearly connecting it with the other parts of the application. See § 1.53(f) and (g) with regard to completion of an application.

(b) Applicant will be informed of the application number and filing date by a filing receipt, unless the application is an application filed under § 1.53(d). A letter limited to a request for a filing receipt may be signed by a juristic applicant or patent owner.

For non-electronic filings, if a self-addressed postcard is submitted with a patent application, that postcard will be provided with both the receipt date and application number prior to returning it to the addressee. The application number identified on such a postcard receipt is merely the preliminary assignment of an application number to the application, and should not be relied upon (e.g., with respect to foreign filings) as necessarily representing the application number assigned to such application. See 37 CFR 1.53(b).

It is important that the return postcard itemize all of the components of the application. If the postcard does not itemize each of the components of the application, it will not serve as evidence that any component which was not itemized was received by the United States Patent and Trademark Office (USPTO). See subsection III, below, for additional information pertaining to return postcards. It should be recognized that the identification of an application by application number does not necessarily signify that the USPTO has accepted the application as complete (37 CFR 1.53(a)).

A provisional application filed on or after December 18, 2013 is entitled to a filing date as of the date of receipt of the specification, with or without claims, in the Office (37 CFR 1.53(c)); a provisional application filed before December 18, 2013 must also include any required drawings to be entitled to a filing date (pre-PLT (AIA) 37 CFR 1.53 (c)). See also MPEP § 608.02, subsection I. See 37 CFR 1.53(c). A cover sheet (37 CFR 1.51(c)(1)), which may be an application data sheet (37 CFR 1.76) or a cover letter, identifying the application as a provisional application is required to prevent the provisional application from being treated as a nonprovisional application. 37 CFR 1.53(c)(1).

A nonprovisional application, other than an application for a design patent including a CPA filed under 37 CFR 1.53(d), is entitled to a filing date as of the date of receipt of the specification, with or without claims. An application for a design patent, other than a CPA filed under 37 CFR 1.53(d), is entitled to a filing date as of the date of receipt of the specification, including at least one claim, and any required drawings. See 37 CFR 1.53(b). A CPA is entitled to a filing date as of the date that a proper request under 37 CFR 1.53(d) is filed. The filing receipt will be mailed at the time a determination is made that the application meets the minimum requirements to receive a filing date. The inventor's oath or declaration, basic filing fee, and search fee and examination fee as set forth in 37 CFR 1.16, may be filed later than the remaining application papers, but if so, they must be accompanied by the required surcharge (if appropriate, see MPEP § 506). See 37 CFR 1.53(f). If the inventor's oath or declaration, basic filing fee, and/or any required search fee and examination fee with the appropriate surcharge are not timely filed, the application will be abandoned. For original (non-reissue) applications filed on or after September 16, 2012, the filing of the inventor’s oath or declaration may be postponed until the date the issue fee is paid if an application data sheet in accordance with 37 CFR 1.76 is timely filed providing the required inventor information. See 35 U.S.C. 115(f) and 37 CFR 1.53(f). The surcharge required for filing the inventor’s oath or declaration after the filing date of the application, however, must be paid on filing of the application or in response to a Notice to File Missing Parts. Also, for applications filed on or after December 18, 2013, the filing of at least one claim may be postponed until the expiration of the time period set in Notice to File Missing Parts. Claim(s) and the surcharge must be filed in response to the Notice to File Missing Parts. See MPEP § 506.

If a submitter desires a receipt for any item (e.g., paper or fee) filed in the USPTO by means other than the USPTO patent electronic filing system, it may be obtained by enclosing with the paper a self-addressed postcard specifically identifying the item. See subsection I, above, and MPEP § 502.05 for Electronic Acknowledgment Receipts. To ensure the receipt of return receipt postcards, users must either: (A) purchase already stamped postcards from the United States Postal Service (USPS) or affix postage stamps to their postcards; or (B) if a postage meter is used, ensure that the meter postmark does not show the date. Any return receipt postcard containing a dated meter postmark may not be delivered by the USPS to the address provided on the postcard. Users are reminded that they are solely responsible for placing the proper postage on self-addressed postcards that are submitted to the USPTO for the purpose of obtaining a receipt for correspondence being filed in the USPTO. Users should check with the USPS regarding postage and what size cards are acceptable to the USPS. Any return receipt postcard that does not contain sufficient postage or is not acceptable may not be delivered by the USPS to the address provided on the postcard, and, if returned to the USPTO, may be discarded.

If a new application is being filed, all parts of the application being submitted should be separately listed on the postcard, e.g., the number of pages of specification (including written description, claims and abstract), number of claims, number of sheets of drawings, number of pages of oath/declaration, number of pages of cover sheet (provisional application).

For applications filed via the USPTO patent electronic filing system, after the Office receives a successful submission, an Electronic Acknowledgement Receipt is provided to the person filing the application. The acknowledgment receipt contains the "receipt date," the time the correspondence was received at the Office (not the local time at the submitter's location), and a full listing of the correspondence submitted. The Electronic Acknowledgement Receipt is the electronic equivalent of a postcard receipt. See MPEP § 502.05.

The identifying data on the postcard should include:

• (A) inventor’s name(s);
• (B) title of invention;
• (C) number of pages of specification, claims (for nonprovisional applications), and sheet(s) of drawing(s);
• (D) whether the inventor's oath or declaration is included;
• (E) a list of any additional forms included with the application (e.g., application transmittal form, application data sheet, fee transmittal form, and/or provisional application cover sheet); and
• (F) amount and manner of paying the fee.

The postcard receipt will not serve as prima facie evidence of receipt of any item which is not adequately itemized on the postcard. For example, merely listing on the postcard “a complete application” or “patent application” will not serve as a proper receipt for each of the required components of an application (e.g., specification (including claims), drawings (if necessary), oath or declaration and the application filing fee) or missing portions (e.g., pages, sheets of drawings) of an application if one of the components or portion of a component is found to be missing by the USPTO. Each separate component should be specifically and properly itemized on the postcard. Furthermore, merely incorporating by reference in the postcard receipt, the items listed in a transmittal letter will not serve as prima facie evidence of receipt of those items.

Attorney docket numbers must be limited to a maximum of 25 characters to prevent truncation. The USPTO system data base allows a maximum of 25 characters for the attorney docket numbers. Spaces, slashes, and hyphens will no longer be included in the entered docket number on the official filing receipt. In an application where CASE or NAVY-CASE appears before the first character in the docket number, only the characters after CASE or NAVY-CASE will be entered on the official filing receipt.

A nonprovisional application, other than an application for a design patent including a CPA filed under 37 CFR 1.53(d), is entitled to a filing date as of the date of receipt of the specification, with or without claims. An application for a design patent, other than a CPA filed under 37 CFR 1.53(d), is entitled to a filing date as of the date of receipt of the specification, including at least one claim, and any required drawings. See 37 CFR 1.53(b). A CPA is entitled to a filing date as of the date that a proper request under 37 CFR 1.53(d) is filed. The filing receipt will be mailed at the time a determination is made that the application meets the minimum requirements to receive a filing date. The inventor's oath or declaration, basic filing fee, and search fee and examination fee as set forth in 37 CFR 1.16, may be filed later than the remaining application papers, but if so, they must be accompanied by the required surcharge (if appropriate, see MPEP § 506). See 37 CFR 1.53(f). If the inventor's oath or declaration, basic filing fee, and/or any required search fee and examination fee with the appropriate surcharge are not timely filed, the application will be abandoned. For original (non-reissue) applications filed on or after September 16, 2012, the filing of the inventor’s oath or declaration may be postponed until the date the issue fee is paid if an application data sheet in accordance with 37 CFR 1.76 is timely filed providing the required inventor information. See 35 U.S.C. 115(f) and 37 CFR 1.53(f). The surcharge required for filing the inventor’s oath or declaration after the filing date of the application, however, must be paid on filing of the application or in response to a Notice to File Missing Parts. Also, for applications filed on or after December 18, 2013, the filing of at least one claim may be postponed until the expiration of the time period set in Notice to File Missing Parts. Claim(s) and the surcharge must be filed in response to the Notice to File Missing Parts. See MPEP § 506.

OPAP mails a filing receipt to the attorney or agent, if any, otherwise to the applicant, at the correspondence address of record for each application filed which meets the minimum requirements to receive a filing date. The filing receipt includes the application number, filing date, a confirmation number, and, if available, the number of an art unit where the application is likely to be examined. The filing receipt also includes other information about the application as applicable, such as continuing data, national stage data, foreign priority data, foreign filing license data, entity status information, and the date the Office anticipates publishing the application under 35 U.S.C. 122(b). The filing receipt represents the official assignment by the USPTO of a specific application number and confirmation number to a particular application. See 37 CFR 1.54(b). The application number officially assigned to an application on the filing receipt may differ from the application number identified on a postcard receipt submitted with such application, and, as between inconsistent filing receipts and postcard receipts, the application number on the filing receipt is controlling.

The postcard receipt will not serve as prima facie evidence of receipt of any item which is not adequately itemized on the postcard. For example, merely listing on the postcard “a complete application” or “patent application” will not serve as a proper receipt for each of the required components of an application (e.g., specification (including claims), drawings (if necessary), oath or declaration and the application filing fee) or missing portions (e.g., pages, sheets of drawings) of an application if one of the components or portion of a component is found to be missing by the USPTO. Each separate component should be specifically and properly itemized on the postcard. Furthermore, merely incorporating by reference in the postcard receipt, the items listed in a transmittal letter will not serve as prima facie evidence of receipt of those items.
