An application for a patent filed under paragraphs (b) or (d) of this section will not be placed on the files for examination until all its required parts, complying with the rules relating thereto, are received, except that the inventor's oath or declaration may be filed when the application is otherwise in condition for allowance pursuant to paragraph (f)(3) of this section and minor informalities may be waived subject to subsequent correction whenever required.

37 CFR 1.53 relates to application numbers, filing dates, and completion of applications. Note that the substantive requirements under 37 CFR 1.53 for applications filed on or after September 16, 2012 as compared to those filed prior to September 16, 2012 (pre-AIA) are the same with the exception of 37 CFR 1.53(f), pertaining to completion of a nonprovisional application subsequent to filing. Also, note that the filing date requirements under 37 CFR 1.53(b) and (c) for applications filed on or after December 18, 2013 are different from those filed prior to December 18, 2013. For example, under 37 CFR 1.53(b), except for design applications, nonprovisional applications filed on or after December 18, 2013 may receive a filing date even if the application is filed without claims or drawings. See MPEP § 601.01(a) for additional information. Similarly, provisional applications filed on or after December 18, 2013 may receive a filing date even if the application is filed without drawings. See MPEP § 601.01(b) for additional information. If the subject matter of a nonprovisional application admits of illustration by a drawing to facilitate understanding of the invention, including where a drawing is necessary for the understanding of the invention, the Office will continue the practice of requiring a drawing. See MPEP § 608.02 (item IV). Any claim or any drawing submitted after the filing date of an application may not contain new matter. 37 CFR 1.53(a) indicates that an application number is assigned for identification purposes to any paper which purports to be an application for a patent, even if the application is incomplete or informal. The remaining sections of 37 CFR 1.53 treat nonprovisional applications filed under 35 U.S.C. 111(a) separately from provisional applications filed under 35 U.S.C. 111(b).

Also, note that the filing date requirements under 37 CFR 1.53(b) and (c) for applications filed on or after December 18, 2013 are different from those filed prior to December 18, 2013. For example, under 37 CFR 1.53(b), except for design applications, nonprovisional applications filed on or after December 18, 2013 may receive a filing date even if the application is filed without claims or drawings. See MPEP § 601.01(a) for additional information. Similarly, provisional applications filed on or after December 18, 2013 may receive a filing date even if the application is filed without drawings. See MPEP § 601.01(b) for additional information. If the subject matter of a nonprovisional application admits of illustration by a drawing to facilitate understanding of the invention, including where a drawing is necessary for the understanding of the invention, the Office will continue the practice of requiring a drawing. See MPEP § 608.02 (item IV). Any claim or any drawing submitted after the filing date of an application may not contain new matter. 37 CFR 1.53(a) indicates that an application number is assigned for identification purposes to any paper which purports to be an application for a patent, even if the application is incomplete or informal.

[Editor Note: Paragraphs (b), (c), (f) and (h) below have limited applicability as follows:
(c) Application filing requirements — Provisional application. The filing date of a provisional application is the date on which a specification, with or without claims, is received in the Office. No amendment, other than to make the provisional application comply with the patent statute and all applicable regulations, may be made to the provisional application after the filing date of the provisional application. (1) A provisional application must also include the cover sheet required by § 1.51(c)(1), which may be an application data sheet (§ 1.76), or a cover letter identifying the application as a provisional application. Otherwise, the application will be treated as an application filed under paragraph (b) of this section.

…
A provisional application disclosing nucleotide and/or amino acid sequences is not required to include a separate sequence listing; however, if submitted in a provisional application filed on or after July 1, 2022, any submission of nucleotide and/or amino acid sequence data must be by way of a “Sequence Listing XML” in compliance with §§ 1.831 through 1.834.

(c) Application filing requirements — Provisional application. The filing date of a provisional application is the date on which a specification, with or without claims, is received in the Office. No amendment, other than to make the provisional application comply with the patent statute and all applicable regulations, may be made to the provisional application after the filing date of the provisional application.

• (1) A provisional application must also include the cover sheet required by § 1.51(c)(1), which may be an application data sheet (§ 1.76), or a cover letter identifying the application as a provisional application. Otherwise, the application will be treated as an application filed under paragraph (b) of this section.
• (2) An application for patent filed under paragraph (b) of this section may be converted to a provisional application and be accorded the original filing date of the application filed under paragraph (b) of this section. The grant of such a request for conversion will not entitle applicant to a refund of the fees that were properly paid in the application filed under paragraph (b) of this section. Such a request for conversion must be accompanied by the processing fee set forth in § 1.17(q) and be filed prior to the earliest of:
  • (i) Abandonment of the application filed under paragraph (b) of this section;
  • (ii) Payment of the issue fee on the application filed under paragraph (b) of this section; or
  • (iii) Expiration of twelve months after the filing date of the application filed under paragraph (b) of this section.
• (3) A provisional application filed under paragraph (c) of this section may be converted to a nonprovisional application filed under paragraph (b) of this section and accorded the original filing date of the provisional application. The conversion of a provisional application to a nonprovisional application will not result in either the refund of any fee properly paid in the provisional application or the application of any such fee to the filing fee, or any other fee, for the nonprovisional application. Conversion of a provisional application to a nonprovisional application under this paragraph will result in the term of any patent to issue from the application being measured from at least the filing date of the provisional application for which conversion is requested. Thus, applicants should consider avoiding this adverse patent term impact by filing a nonprovisional application claiming the benefit of the provisional application under 35 U.S.C. 119(e), rather than converting the provisional application into a nonprovisional application pursuant to this paragraph. A request to convert a provisional application to a nonprovisional application must be accompanied by the fee set forth in § 1.17(i) and an amendment including at least one claim as prescribed by 35 U.S.C. 112(b), unless the provisional application under paragraph (c) of this section otherwise contains at least one claim as prescribed by 35 U.S.C. 112(b). The nonprovisional application resulting from conversion of a provisional application must also include the filing fee, search fee, and examination fee for a nonprovisional application, and the surcharge required by § 1.16(f) if either the basic filing fee for a nonprovisional application or the inventor's oath or declaration was not present on the filing date accorded the resulting nonprovisional application (i.e., the filing date of the original provisional application). A request to convert a provisional application to a nonprovisional application must also be filed prior to the earliest of:
  • (i) Abandonment of the provisional application filed under paragraph (c) of this section; or
  • (ii) Expiration of twelve months after the filing date of the provisional application filed under paragraph (c) of this section.
• (4) A provisional application is not entitled to the right of priority under 35 U.S.C. 119, 365(a), or 386(a) or § 1.55, or to the benefit of an earlier filing date under 35 U.S.C. 120, 121, 365(c), or 386(c) or § 1.78 of any other application. No claim for priority under 35 U.S.C. 119(e) or § 1.78(a) may be made in a design application based on a provisional application. A provisional application disclosing nucleotide and/or amino acid sequences is not required to include a separate sequence listing; however, if submitted in a provisional application filed on or after July 1, 2022, any submission of nucleotide and/or amino acid sequence data must be by way of a “Sequence Listing XML” in compliance with §§ 1.831 through 1.834.

(3) A provisional application filed under paragraph (c) of this section may be converted to a nonprovisional application filed under paragraph (b) of this section and accorded the original filing date of the provisional application. The conversion of a provisional application to a nonprovisional application will not result in either the refund of any fee properly paid in the provisional application or the application of any such fee to the filing fee, or any other fee, for the nonprovisional application. Conversion of a provisional application to a nonprovisional application under this paragraph will result in the term of any patent to issue from the application being measured from at least the filing date of the provisional application for which conversion is requested. Thus, applicants should consider avoiding this adverse patent term impact by filing a nonprovisional application claiming the benefit of the provisional application under 35 U.S.C. 119(e), rather than converting the provisional application into a nonprovisional application pursuant to this paragraph. A request to convert a provisional application to a nonprovisional application must be accompanied by the fee set forth in § 1.17(i) and an amendment including at least one claim as prescribed by 35 U.S.C. 112(b), unless the provisional application under paragraph (c) of this section otherwise contains at least one claim as prescribed by 35 U.S.C. 112(b). The nonprovisional application resulting from conversion of a provisional application must also include the filing fee, search fee, and examination fee for a nonprovisional application, and the surcharge required by § 1.16(f) if either the basic filing fee for a nonprovisional application or the inventor's oath or declaration was not present on the filing date accorded the resulting nonprovisional application (i.e., the filing date of the original provisional application). A request to convert a provisional application to a nonprovisional application must also be filed prior to the earliest of:
…
(ii) Expiration of twelve months after the filing date of the provisional application filed under paragraph (c) of this section.

[Editor Note: Paragraphs (b), (c), (f) and (h) below have limited applicability as follows:
(g) Completion of application subsequent to filing — Provisional application.

See pre-AIA 37 CFR 1.53 for paragraphs (f) and (h) otherwise in effect.

37 CFR 1.53 relates to application numbers, filing dates, and completion of applications. Note that the substantive requirements under 37 CFR 1.53 for applications filed on or after September 16, 2012 as compared to those filed prior to September 16, 2012 (pre-AIA) are the same with the exception of 37 CFR 1.53(f), pertaining to completion of a nonprovisional application subsequent to filing. Also, note that the filing date requirements under 37 CFR 1.53(b) and (c) for applications filed on or after December 18, 2013 are different from those filed prior to December 18, 2013. For example, under 37 CFR 1.53(b), except for design applications, nonprovisional applications filed on or after December 18, 2013 may receive a filing date even if the application is filed without claims or drawings. See MPEP § 601.01(a) for additional information. Similarly, provisional applications filed on or after December 18, 2013 may receive a filing date even if the application is filed without drawings. See MPEP § 601.01(b) for additional information. If the subject matter of a nonprovisional application admits of illustration by a drawing to facilitate understanding of the invention, including where a drawing is necessary for the understanding of the invention, the Office will continue the practice of requiring a drawing. See MPEP § 608.02 (item IV). Any claim or any drawing submitted after the filing date of an application may not contain new matter. 37 CFR 1.53(a) indicates that an application number is assigned for identification purposes to any paper which purports to be an application for a patent, even if the application is incomplete or informal. The remaining sections of 37 CFR 1.53 treat nonprovisional applications filed under 35 U.S.C. 111(a) separately from provisional applications filed under 35 U.S.C. 111(b).

(b) Application filing requirements — Nonprovisional application. The filing date of an application for patent filed under this section, other than an application for a design patent or a provisional application under paragraph (c) of this section, is the date on which a specification, with or without claims, is received in the Office. The filing date of an application for a design patent filed under this section, except for a continued prosecution application under paragraph (d) of this section, is the date on which the specification as prescribed by 35 U.S.C. 112, including at least one claim, and any required drawings are received in the Office. No new matter may be introduced into an application after its filing date. A continuing application, which may be a continuation, divisional, or continuation-in-part application, may be filed under the conditions specified in 35 U.S.C. 120, 121, 365(c), or 386(c) and § 1.78.

• (a) Application number. Any papers received in the Patent and Trademark Office which purport to be an application for a patent will be assigned an application number for identification purposes.
• (b) Application filing requirements — Nonprovisional application. The filing date of an application for patent filed under this section, other than an application for a design patent or a provisional application under paragraph (c) of this section, is the date on which a specification, with or without claims, is received in the Office. The filing date of an application for a design patent filed under this section, except for a continued prosecution application under paragraph (d) of this section, is the date on which the specification as prescribed by 35 U.S.C. 112, including at least one claim, and any required drawings are received in the Office. No new matter may be introduced into an application after its filing date. A continuing application, which may be a continuation, divisional, or continuation-in-part application, may be filed under the conditions specified in 35 U.S.C. 120, 121, 365(c), or 386(c) and § 1.78.
  • (1) A continuation or divisional application that names as inventors the same or fewer than all of the inventors named in the prior application may be filed under this paragraph or paragraph (d) of this section.
  • (2) A continuation-in-part application (which may disclose and claim subject matter not disclosed in the prior application) or a continuation or divisional application naming an inventor not named in the prior application must be filed under this paragraph.
• (c) Application filing requirements — Provisional application. The filing date of a provisional application is the date on which a specification, with or without claims, is received in the Office. No amendment, other than to make the provisional application comply with the patent statute and all applicable regulations, may be made to the provisional application after the filing date of the provisional application.
  • (1) A provisional application must also include the cover sheet required by § 1.51(c)(1), which may be an application data sheet (§ 1.76), or a cover letter identifying the application as a provisional application. Otherwise, the application will be treated as an application filed under paragraph (b) of this section.
  • (2) An application for patent filed under paragraph (b) of this section may be converted to a provisional application and be accorded the original filing date of the application filed under paragraph (b) of this section. The grant of such a request for conversion will not entitle applicant to a refund of the fees that were properly paid in the application filed under paragraph (b) of this section. Such a request for conversion must be accompanied by the processing fee set forth in § 1.17(q) and be filed prior to the earliest of:
    • (i) Abandonment of the application filed under paragraph (b) of this section;
    • (ii) Payment of the issue fee on the application filed under paragraph (b) of this section; or
    • (iii) Expiration of twelve months after the filing date of the application filed under paragraph (b) of this section.
  • (3) A provisional application filed under paragraph (c) of this section may be converted to a nonprovisional application filed under paragraph (b) of this section and accorded the original filing date of the provisional application. The conversion of a provisional application to a nonprovisional application will not result in either the refund of any fee properly paid in the provisional application or the application of any such fee to the filing fee, or any other fee, for the nonprovisional application. Conversion of a provisional application to a nonprovisional application under this paragraph will result in the term of any patent to issue from the application being measured from at least the filing date of the provisional application for which conversion is requested. Thus, applicants should consider avoiding this adverse patent term impact by filing a nonprovisional application claiming the benefit of the provisional application under 35 U.S.C. 119(e), rather than converting the provisional application into a nonprovisional application pursuant to this paragraph. A request to convert a provisional application to a nonprovisional application must be accompanied by the fee set forth in § 1.17(i) and an amendment including at least one claim as prescribed by 35 U.S.C. 112(b), unless the provisional application under paragraph (c) of this section otherwise contains at least one claim as prescribed by 35 U.S.C. 112(b). The nonprovisional application resulting from conversion of a provisional application must also include the filing fee, search fee, and examination fee for a nonprovisional application, and the surcharge required by § 1.16(f) if either the basic filing fee for a nonprovisional application or the inventor's oath or declaration was not present on the filing date accorded the resulting nonprovisional application (i.e., the filing date of the original provisional application). A request to convert a provisional application to a nonprovisional application must also be filed prior to the earliest of:
    • (i) Abandonment of the provisional application filed under paragraph (c) of this section; or
    • (ii) Expiration of twelve months after the filing date of the provisional application filed under paragraph (c) of this section.
  • (4) A provisional application is not entitled to the right of priority under 35 U.S.C. 119, 365(a), or 386(a) or § 1.55, or to the benefit of an earlier filing date under 35 U.S.C. 120, 121, 365(c), or 386(c) or § 1.78 of any other application. No claim for priority under 35 U.S.C. 119(e) or § 1.78(a) may be made in a design application based on a provisional application. A provisional application disclosing nucleotide and/or amino acid sequences is not required to include a separate sequence listing; however, if submitted in a provisional application filed on or after July 1, 2022, any submission of nucleotide and/or amino acid sequence data must be by way of a “Sequence Listing XML” in compliance with §§ 1.831 through 1.834.
• (d) Application filing requirements — Continued prosecution (nonprovisional) application.
  • (1) A continuation or divisional application (but not a continuation-in-part) of a prior nonprovisional application may be filed as a continued prosecution application under this paragraph, provided that:
    • (i) The application is for a design patent;
    • (ii) The prior nonprovisional application is a design application, but not an international design application, that is complete as defined by § 1.51(b) except for the inventor’s oath or declaration if the application is filed on or after September 16, 2012, and the prior nonprovisional application contains an application data sheet meeting the conditions specified in § 1.53(f)(3)(i); and
    • (iii) The application under this paragraph is filed before the earliest of:
      • (A) Payment of the issue fee on the prior application, unless a petition under § 1.313(c) is granted in the prior application;
      • (B) Abandonment of the prior application; or
      • (C) Termination of proceedings on the prior application.
  • (2) The filing date of a continued prosecution application is the date on which a request on a separate paper for an application under this paragraph is filed. An application filed under this paragraph:
    • (i) Must identify the prior application;
    • (ii) Discloses and claims only subject matter disclosed in the prior application;
    • (iii) Names as inventors the same inventors named in the prior application on the date the application under this paragraph was filed, except as provided in paragraph (d)(4) of this section;
    • (iv) Includes the request for an application under this paragraph, will utilize the file jacket and contents of the prior application, including the specification, drawings and the inventor's oath or declaration from the prior application, to constitute the new application, and will be assigned the application number of the prior application for identification purposes; and
    • (v) Is a request to expressly abandon the prior application as of the filing date of the request for an application under this paragraph.
  • (3) The filing fee, search fee, and examination fee for a continued prosecution application filed under this paragraph are the basic filing fee as set forth in § 1.16(b), the search fee as set forth in § 1.16(l), and the examination fee as set forth in § 1.16(p).
  • (4) An application filed under this paragraph may be filed by fewer than all the inventors named in the prior application, provided that the request for an application under this paragraph when filed is accompanied by a statement requesting deletion of the name or names of the person or persons who are not inventors of the invention being claimed in the new application. No person may be named as an inventor in an application filed under this paragraph who was not named as an inventor in the prior application on the date the application under this paragraph was filed, except by way of correction of inventorship under § 1.48.
  • (5) Any new change must be made in the form of an amendment to the prior application as it existed prior to the filing of an application under this paragraph. No amendment in an application under this paragraph (a continued prosecution application) may introduce new matter or matter that would have been new matter in the prior application. Any new specification filed with the request for an application under this paragraph will not be considered part of the original application papers, but will be treated as a substitute specification in accordance with § 1.125.
  • (6) The filing of a continued prosecution application under this paragraph will be construed to include a waiver of confidentiality by the applicant under 35 U.S.C. 122 to the extent that any member of the public, who is entitled under the provisions of § 1.14 to access to, copies of, or information concerning either the prior application or any continuing application filed under the provisions of this paragraph, may be given similar access to, copies of, or similar information concerning the other application or applications in the file jacket.
  • (7) A request for an application under this paragraph is the specific reference required by 35 U.S.C. 120 to every application assigned the application number identified in such request. No amendment in an application under this paragraph may delete this specific reference to any prior application.
  • (8) In addition to identifying the application number of the prior application, applicant should furnish in the request for an application under this paragraph the following information relating to the prior application to the best of his or her ability:
    • (i) Title of invention;
    • (ii) Name of applicant(s); and
    • (iii) Correspondence address.
  • (9) See § 1.103(b) for requesting a limited suspension of action in an application filed under this paragraph.
• (e) Failure to meet filing date requirements.
  • (1) If an application deposited under paragraph (b), (c), or (d) of this section does not meet the requirements of such paragraph to be entitled to a filing date, applicant will be so notified, if a correspondence address has been provided, and given a period of time within which to correct the filing error. If, however, a request for an application under paragraph (d) of this section does not meet the requirements of that paragraph because the application in which the request was filed is not a design application, and if the application in which the request was filed was itself filed on or after June 8, 1995, the request for an application under paragraph (d) of this section will be treated as a request for continued examination under § 1.114.
  • (2) Any request for review of a notification pursuant to paragraph (e)(1) of this section, or a notification that the original application papers lack a portion of the specification or drawing(s), must be by way of a petition pursuant to this paragraph accompanied by the fee set forth in § 1.17(f). In the absence of a timely (§ 1.181(f)) petition pursuant to this paragraph, the filing date of an application in which the applicant was notified of a filing error pursuant to paragraph (e)(1) of this section will be the date the filing error is corrected.
  • (3) If an applicant is notified of a filing error pursuant to paragraph (e)(1) of this section, but fails to correct the filing error within the given time period or otherwise timely (§ 1.181(f)) take action pursuant to this paragraph, proceedings in the application will be considered terminated. Where proceedings in an application are terminated pursuant to this paragraph, the application may be disposed of, and any filing fees, less the handling fee set forth in § 1.21(n), will be refunded.
• (f) Completion of application subsequent to filing — Nonprovisional (including continued prosecution or reissue) application.
  • (1) If an application which has been accorded a filing date pursuant to paragraph (b) or (d) of this section does not include the basic filing fee, search fee, or examination fee, or if an application which has been accorded a filing date pursuant to paragraph (b) of this section does not include at least one claim or the inventor's oath or declaration (§§ 1.63, 1.64, 1.162 or 1.175), and the applicant has provided a correspondence address (§ 1.33(a)), the applicant will be notified and given a period of time within which to file a claim or claims, pay the basic filing fee, search fee, and examination fee, and pay the surcharge if required by § 1.16(f) to avoid abandonment.
  • (2) If an application which has been accorded a filing date pursuant to paragraph (b) of this section does not include the basic filing fee, search fee, examination fee, at least one claim, or the inventor's oath or declaration, and the applicant has not provided a correspondence address (§ 1.33(a)), the applicant has three months from the filing date of the application within which to file a claim or claims, pay the basic filing fee, search fee, and examination fee, and pay the surcharge required by § 1.16(f) to avoid abandonment.
  • (3) The inventor's oath or declaration in an application under § 1.53(b) must also be filed within the period specified in paragraph (f)(1) or (f)(2) of this section, except that the filing of the inventor's oath or declaration may be postponed until the application is otherwise in condition for allowance under the conditions specified in paragraphs (f)(3)(i) and (f)(3)(ii) of this section.
    • (i) The application must be an original (non-reissue) application that contains an application data sheet in accordance with § 1.76 identifying:

      • (B) A mailing address where the inventor customarily receives mail, and residence, if an inventor lives at a location which is different from where the inventor customarily receives mail, for each inventor.
    • (ii) The applicant must file each required oath or declaration in compliance with § 1.63, or substitute statement in compliance with § 1.64, no later than the date on which the issue fee for the patent is paid. If the applicant is notified in a notice of allowability that an oath or declaration in compliance with § 1.63, or substitute statement in compliance with § 1.64, executed by or with respect to each named inventor has not been filed, the applicant must file each required oath or declaration in compliance with § 1.63, or substitute statement in compliance with § 1.64, no later than the date on which the issue fee is paid to avoid abandonment. This time period is not extendable under § 1.136 (see § 1.136(c)). The Office may dispense with the notice provided for in paragraph (f)(1) of this section if each required oath or declaration in compliance with § 1.63, or substitute statement in compliance with § 1.64, has been filed before the application is in condition for allowance.
  • (4) If the excess claims fees required by § 1.16(h) and (i) and multiple dependent claim fee required by § 1.16(j) are not paid on filing or on later presentation of the claims for which the excess claims or multiple dependent claim fees are due, the fees required by § 1.16(h), (i), and (j) must be paid or the claims canceled by amendment prior to the expiration of the time period set for reply by the Office in any notice of fee deficiency. If the application size fee required by § 1.16(s) (if any) is not paid on filing or on later presentation of the amendment necessitating a fee or additional fee under § 1.16(s), the fee required by § 1.16(s) must be paid prior to the expiration of the time period set for reply by the Office in any notice of fee deficiency in order to avoid abandonment.
  • (5) This paragraph applies to continuation or divisional applications under paragraphs (b) or (d) of this section and to continuation-in-part applications under paragraph (b) of this section. See § 1.63(d) concerning the submission of a copy of the inventor's oath or declaration from the prior application for a continuing application under paragraph (b) of this section.
  • (6) If applicant does not pay the basic filing fee during the pendency of the application, the Office may dispose of the application.
• (g) Completion of application subsequent to filing — Provisional application.
  • (1) If a provisional application which has been accorded a filing date pursuant to paragraph (c) of this section does not include the cover sheet required by § 1.51(c)(1) or the basic filing fee (§ 1.16(d)), and applicant has provided a correspondence address (§ 1.33(a)), applicant will be notified and given a period of time within which to pay the basic filing fee, file a cover sheet (§ 1.51(c)(1)), and pay the surcharge required by § 1.16(g) to avoid abandonment.
  • (2) If a provisional application which has been accorded a filing date pursuant to paragraph (c) of this section does not include the cover sheet required by § 1.51(c)(1) or the basic filing fee (§ 1.16(d)), and applicant has not provided a correspondence address (§ 1.33(a)), applicant has two months from the filing date of the application within which to pay the basic filing fee, file a cover sheet (§ 1.51(c)(1)), and pay the surcharge required by § 1.16(g) to avoid abandonment.

37 CFR 1.53 relates to application numbers, filing dates, and completion of applications. Note that the substantive requirements under 37 CFR 1.53 for applications filed on or after September 16, 2012 as compared to those filed prior to September 16, 2012 (pre-AIA) are the same with the exception of 37 CFR 1.53(f), pertaining to completion of a nonprovisional application subsequent to filing. Also, note that the filing date requirements under 37 CFR 1.53(b) and (c) for applications filed on or after December 18, 2013 are different from those filed prior to December 18, 2013. For example, under 37 CFR 1.53(b), except for design applications, nonprovisional applications filed on or after December 18, 2013 may receive a filing date even if the application is filed without claims or drawings. See MPEP § 601.01(a) for additional information. Similarly, provisional applications filed on or after December 18, 2013 may receive a filing date even if the application is filed without drawings. See MPEP § 601.01(b) for additional information. If the subject matter of a nonprovisional application admits of illustration by a drawing to facilitate understanding of the invention, including where a drawing is necessary for the understanding of the invention, the Office will continue the practice of requiring a drawing. See MPEP § 608.02 (item IV). Any claim or any drawing submitted after the filing date of an application may not contain new matter. 37 CFR 1.53(a) indicates that an application number is assigned for identification purposes to any paper which purports to be an application for a patent, even if the application is incomplete or informal. The remaining sections of 37 CFR 1.53 treat nonprovisional applications filed under 35 U.S.C. 111(a) separately from provisional applications filed under 35 U.S.C. 111(b).
