              TITLE 37--PATENTS, TRADEMARKS, AND COPYRIGHTS
 
  CHAPTER I--UNITED STATES PATENT AND TRADEMARK OFFICE, DEPARTMENT OF 
                                COMMERCE
 
PART 1_RULES OF PRACTICE IN PATENT CASES--Table of Contents
 
                      Subpart A_General Provisions
 
Sec. 1.4  Nature of correspondence and signature requirements.

    (a) Correspondence with the Patent and Trademark Office comprises:
    (1) Correspondence relating to services and facilities of the 
Office, such as general inquiries, requests for publications supplied by 
the Office, orders for printed copies of patents, orders for copies of 
records, transmission of assignments for recording, and the like, and
    (2) Correspondence in and relating to a particular application or 
other proceeding in the Office. See particularly the rules relating to 
the filing, processing, or other proceedings of national applications in 
subpart B, Sec. Sec. 1.31 to 1.378; of international applications in 
subpart C, Sec. Sec. 1.401 to 1.499; of ex parte reexaminations of 
patents in subpart D,

[[Page 13]]

Sec. Sec. 1.501 to 1.570; of extension of patent term in subpart F, 
Sec. Sec. 1.710 to 1.785; of inter partes reexaminations of patents in 
subpart H, Sec. Sec. 1.902 to 1.997; and of the Board of Patent Appeals 
and Interferences in part 41 of this title.
    (b) Since each file must be complete in itself, a separate copy of 
every paper to be filed in a patent application, patent file, or other 
proceeding must be furnished for each file to which the paper pertains, 
even though the contents of the papers filed in two or more files may be 
identical. The filing of duplicate copies of correspondence in the file 
of an application, patent, or other proceeding should be avoided, except 
in situations in which the Office requires the filing of duplicate 
copies. The Office may dispose of duplicate copies of correspondence in 
the file of an application, patent, or other proceeding.
    (c) Since different matters may be considered by different branches 
or sections of the United States Patent and Trademark Office, each 
distinct subject, inquiry or order must be contained in a separate paper 
to avoid confusion and delay in answering papers dealing with different 
subjects.
    (d)(1) Handwritten signature. Each piece of correspondence, except 
as provided in paragraphs (d)(2), (d)(3), (e) and (f) of this section, 
filed in an application, patent file, or other proceeding in the Office 
which requires a person's signature, must:
    (i) Be an original, that is, have an original handwritten signature 
personally signed, in permanent dark ink or its equivalent, by that 
person; or
    (ii) Be a direct or indirect copy, such as a photocopy or facsimile 
transmission (Sec. 1.6(d)), of an original. In the event that a copy of 
the original is filed, the original should be retained as evidence of 
authenticity. If a question of authenticity arises, the Office may 
require submission of the original.
    (2) S-signature. An S-signature is a signature inserted between 
forward slash marks, but not a handwritten signature as defined by Sec. 
1.4(d)(1). An S-signature includes any signature made by electronic or 
mechanical means, and any other mode of making or applying a signature 
not covered by a handwritten signature of Sec. 1.4(d)(1). 
Correspondence being filed in the Office in paper, by facsimile 
transmission as provided in Sec. 1.6(d), or via the Office electronic 
filing system as an attachment as provided in Sec. 1.6(a)(4), for a 
patent application, patent, or a reexamination proceeding may be S-
signature signed instead of being personally signed (i.e., with a 
handwritten signature) as provided for in paragraph (d)(1) of this 
section. The requirements for an S-signature under this paragraph (d)(2) 
of this section are as follows.
    (i) The S-signature must consist only of letters, or Arabic 
numerals, or both, with appropriate spaces and commas, periods, 
apostrophes, or hyphens for punctuation, and the person signing the 
correspondence must insert his or her own S-signature with a first 
single forward slash mark before, and a second single forward slash mark 
after, the S-signature (e.g., /Dr. James T. Jones, Jr./); and
    (ii) A patent practitioner (Sec. 1.32(a)(1)), signing pursuant to 
Sec. Sec. 1.33(b)(1) or 1.33(b)(2), must supply his/her registration 
number either as part of the S-signature, or immediately below or 
adjacent to the S-signature. The number () character may be 
used only as part of the S-signature when appearing before a 
practitioner's registration number; otherwise the number character may 
not be used in an S-signature.
    (iii) The signer's name must be:
    (A) Presented in printed or typed form preferably immediately below 
or adjacent the S-signature, and
    (B) Reasonably specific enough so that the identity of the signer 
can be readily recognized.
    (3) Forms. The Office provides forms to the public to use in certain 
situations to assist in the filing of correspondence for a certain 
purpose and to meet certain requirements for patent applications and 
proceedings. Use of the forms for purposes for which they were not 
designed is prohibited. No changes to certification statements on the 
Office forms (e.g., oath or declaration forms, terminal disclaimer 
forms, petition forms, and nonpublication request form) may be made. The 
existing text of a form, other than a certification statement, may be 
modified, deleted, or added to, if all text identifying the form as an 
Office form

[[Page 14]]

is removed. The presentation to the Office (whether by signing, filing, 
submitting, or later advocating) of any Office form with text 
identifying the form as an Office form by a party, whether a 
practitioner or non-practitioner, constitutes a certification under 
Sec. 10.18(b) of this chapter that the existing text and any 
certification statements on the form have not been altered other than 
permitted by EFS-Web customization.
    (4) Certifications. (i) Section 10.18 certifications: The 
presentation to the Office (whether by signing, filing, submitting, or 
later advocating) of any paper by a party, whether a practitioner or 
non-practitioner, constitutes a certification under Sec. 10.18(b) of 
this chapter. Violations of Sec. 10.18(b)(2) of this chapter by a 
party, whether a practitioner or non-practitioner, may result in the 
imposition of sanctions under Sec. 10.18(c) of this chapter. Any 
practitioner violating Sec. 10.18(b) of this chapter may also be 
subject to disciplinary action. See Sec. Sec. 10.18(d) and 10.23(c)(15) 
of this chapter.
    (ii) Certifications as to the signature:
    (A) Of another: A person submitting a document signed by another 
under paragraph (d)(2) of this section is obligated to have a reasonable 
basis to believe that the person whose signature is present on the 
document was actually inserted by that person, and should retain 
evidence of authenticity of the signature.
    (B) Self certification: The person inserting a signature under 
paragraph (d)(2) of this section in a document submitted to the Office 
certifies that the inserted signature appearing in the document is his 
or her own signature.
    (e) Correspondence requiring a person's signature and relating to 
registration practice before the Patent and Trademark Office in patent 
cases, enrollment and disciplinary investigations, or disciplinary 
proceedings must be submitted with an original handwritten signature 
personally signed in permanent dark ink or its equivalent by that 
person.
    (f) When a document that is required by statute to be certified must 
be filed, a copy, including a photocopy or facsimile transmission, of 
the certification is not acceptable.
    (g) An applicant who has not made of record a registered attorney or 
agent may be required to state whether assistance was received in the 
preparation or prosecution of the patent application, for which any 
compensation or consideration was given or charged, and if so, to 
disclose the name or names of the person or persons providing such 
assistance. Assistance includes the preparation for the applicant of the 
specification and amendments or other papers to be filed in the Patent 
and Trademark Office, as well as other assistance in such matters, but 
does not include merely making drawings by draftsmen or stenographic 
services in typing papers.
    (h) Ratification/confirmation/evidence of authenticity: The Office 
may require ratification, confirmation (which includes submission of a 
duplicate document but with a proper signature), or evidence of 
authenticity of a signature, such as when the Office has reasonable 
doubt as to the authenticity (veracity) of the signature, e.g., where 
there are variations of a signature, or where the signature and the 
typed or printed name, do not clearly identify the person signing.
