    CHAPTER I--PATENT AND TRADEMARK OFFICE, DEPARTMENT OF COMMERCE
 
PART 1--RULES OF PRACTICE IN PATENT CASES--Table of Contents
 
                Subpart B--National Processing Provisions
 
Sec. 1.53  Application number, filing date, and completion of application.

    (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, 
except for a provisional application under paragraph (c) of this section 
or a continued prosecution application under paragraph (d) of this 
section, is the date on which a specification as prescribed by 35 U.S.C. 
112 containing a description pursuant to Sec. 1.71 and at least one 
claim pursuant to Sec. 1.75, and any drawing required by Sec. 1.81(a) 
are filed in the Patent and Trademark Office. No new matter may be 
introduced into an application after

[[Page 36]]

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 or 365(c) and Sec. 1.78(a).
    (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 as prescribed by the first paragraph of 35 U.S.C. 112, and 
any drawing required by Sec. 1.81(a) are filed in the Patent and 
Trademark 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 Sec. 1.51(c)(1) 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,
    (i) Provided that a petition requesting the conversion, with the fee 
set forth in Sec. 1.17(q), is filed prior to the earliest of:
    (A) Abandonment of the application filed under paragraph (b) of this 
section;
    (B) Payment of the issue fee on the application filed under 
paragraph (b) of this section;
    (C) Expiration of twelve months after the filing date of the 
application filed under paragraph (b) of this section; or
    (D) The filing of a request for a statutory invention registration 
under Sec. 1.293 in the application filed under paragraph (b) of this 
section.
    (ii) The grant of any such petition will not entitle applicant to a 
refund of the fees which were properly paid in the application filed 
under paragraph (b) of this section.
    (3) A provisional application is not entitled to the right of 
priority under 35 U.S.C. 119 or 365(a) or Sec. 1.55, or to the benefit 
of an earlier filing date under 35 U.S.C. 120, 121 or 365(c) or 
Sec. 1.78 of any other application. No claim for priority under 
Sec. 1.78(a)(3) may be made in a design application based on a 
provisional application. No request under Sec. 1.293 for a statutory 
invention registration may be filed in a provisional application. The 
requirements of Secs. 1.821 through 1.825 regarding application 
disclosures containing nucleotide and/or amino acid sequences are not 
mandatory for provisional applications.
    (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 prior nonprovisional application is either:
    (A) Complete as defined by Sec. 1.51(b); or
    (B) The national stage of an international application in compliance 
with 35 U.S.C. 371; and
    (ii) 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 Sec. 1.313(b)(5) 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:

[[Page 37]]

    (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 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 for a continued prosecution application filed 
under this paragraph is:
    (i) The basic filing fee as set forth in Sec. 1.16; and
    (ii) Any additional Sec. 1.16 fee due based on the number of claims 
remaining in the application after entry of any amendment accompanying 
the request for an application under this paragraph and entry of any 
amendments under Sec. 1.116 unentered in the prior application which 
applicant has requested to be entered in the continued prosecution 
application.
    (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 a petition under Sec. 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 Sec. 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 Sec. 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) Envelopes containing only requests and fees for filing an 
application under this paragraph should be marked ``Box CPA.'' Requests 
for an application under this paragraph filed by facsimile transmission 
should be clearly marked ``Box CPA.''
    (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

[[Page 38]]

been provided, and given a time period within which to correct the 
filing error.
    (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. Any petition under this 
paragraph must be accompanied by the fee set forth in Sec. 1.17(i) in an 
application filed under paragraphs (b) or (d) of this section, and the 
fee set forth in Sec. 1.17(q) in an application filed under paragraph 
(c) of this section. In the absence of a timely (Sec. 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 (Sec. 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 
Sec. 1.21(n), will be refunded.
    (f) Completion of application subsequent to filing--Nonprovisional 
(including continued prosecution) application. If an application which 
has been accorded a filing date pursuant to paragraph (b) of this 
section, including a continuation, divisional, or continuation-in-part 
application, does not include the appropriate filing fee or an oath or 
declaration by the applicant pursuant to Sec. 1.63 or Sec. 1.175, or, if 
an application which has been accorded a filing date pursuant to 
paragraph (d) of this section does not include the appropriate filing 
fee, applicant will be so notified, if a correspondence address has been 
provided, and given a period of time within which to file the fee, oath 
or declaration, and the surcharge as set forth in Sec. 1.16(e) in order 
to prevent abandonment of the application. See Sec. 1.63(d) concerning 
the submission of a copy of the oath or declaration from the prior 
application for a continuation or divisional application. If the 
required filing fee is not timely paid, or if the processing and 
retention fee set forth in Sec. 1.21(l) is not paid within one year of 
the date of mailing of the notification required by this paragraph, the 
application may be disposed of. The notification pursuant to this 
paragraph may be made simultaneously with any notification pursuant to 
paragraph (e) of this section. If no correspondence address is included 
in the application, applicant has two months from the filing date to 
file the basic filing fee, the oath or declaration in an application 
under paragraph (b) of this section, and the surcharge as set forth in 
Sec. 1.16(e) in order to prevent abandonment of the application; or, if 
no basic filing fee has been paid, one year from the filing date to pay 
the processing and retention fee set forth in Sec. 1.21(l) to prevent 
disposal of the application.
    (g) Completion of application subsequent to filing--Provisional 
application. If a provisional application which has been accorded a 
filing date pursuant to paragraph (c) of this section does not include 
the appropriate filing fee or the cover sheet required by 
Sec. 1.51(c)(1), applicant will be so notified, if a correspondence 
address has been provided, and given a period of time within which to 
file the fee, cover sheet, and the surcharge as set forth in 
Sec. 1.16(l) in order to prevent abandonment of the application. If the 
required filing fee is not timely paid, the application may be disposed 
of. The notification pursuant to this paragraph may be made 
simultaneously with any notification pursuant to paragraph (e) of this 
section. If no correspondence address is included in the application, 
applicant has two months from the filing date to file the basic filing 
fee, cover sheet, and the surcharge as set forth in Sec. 1.16(l) in 
order to prevent abandonment of the application.
    (h) Subsequent treatment of application--Nonprovisional (including 
continued prosecution) application. 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

[[Page 39]]

with the rules relating thereto, are received, except that certain minor 
informalities may be waived subject to subsequent correction whenever 
required.
    (i) Subsequent treatment of application--Provisional application. A 
provisional application for a patent filed under paragraph (c) of this 
section will not be placed on the files for examination and will become 
abandoned no later than twelve months after its filing date pursuant to 
35 U.S.C. 111(b)(1).
    (j) Filing date of international application. The filing date of an 
international application designating the United States of America is 
treated as the filing date in the United States of America under PCT 
Article 11(3), except as provided in 35 U.S.C. 102(e).
