Sec. 1.52  Language, paper, writing, margins, compact disc specifications.

    (a) Papers that are to become a part of the permanent United States 
Patent and Trademark Office records in the file of a patent application 
or a reexamination proceeding. (1) All papers, other than drawings, that 
are submitted on paper or by facsimile transmission, and are to become a 
part of the permanent United States Patent and Trademark Office records 
in the file of a patent application or reexamination proceeding, must be 
on sheets of paper that are the same size, not permanently bound 
together, and:
    (i) Flexible, strong, smooth, non-shiny, durable, and white;

[[Page 47]]

    (ii) Either 21.0 cm by 29.7 cm (DIN size A4) or 21.6 cm by 27.9 cm 
(8\1/2\ by 11 inches), with each sheet including a top margin of at 
least 2.0 cm (\3/4\ inch), a left side margin of at least 2.5 cm (1 
inch), a right side margin of at least 2.0 cm (\3/4\ inch), and a bottom 
margin of at least 2.0 cm (\3/4\ inch);
    (iii) Written on only one side in portrait orientation;
    (iv) Plainly and legibly written either by a typewriter or machine 
printer in permanent dark ink or its equivalent; and
    (v) Presented in a form having sufficient clarity and contrast 
between the paper and the writing thereon to permit the direct 
reproduction of readily legible copies in any number by use of 
photographic, electrostatic, photo-offset, and microfilming processes 
and electronic capture by use of digital imaging and optical character 
recognition.
    (2) All papers that are submitted on paper or by facsimile 
transmission and are to become a part of the permanent records of the 
United States Patent and Trademark Office should have no holes in the 
sheets as submitted.
    (3) The provisions of this paragraph and paragraph (b) of this 
section do not apply to the pre-printed information on paper forms 
provided by the Office, or to the copy of the patent submitted on paper 
in double column format as the specification in a reissue application or 
request for reexamination.
    (4) See Sec. 1.58 for chemical and mathematical formulae and 
tables, and Sec. 1.84 for drawings.
    (5) Papers that are submitted electronically to the Office must be 
formatted and transmitted in compliance with the Office's electronic 
filing system requirements.
    (b) The application (specification, including the claims, drawings, 
and oath or declaration) or reexamination proceeding and any amendments 
or corrections to the application or reexamination proceeding. (1) The 
application or proceeding and any amendments or corrections to the 
application (including any translation submitted pursuant to paragraph 
(d) of this section) or proceeding, except as provided for in Sec. 1.69 
and paragraph (d) of this section, must:
    (i) Comply with the requirements of paragraph (a) of this section; 
and
    (ii) Be in the English language or be accompanied by a translation 
of the application and a translation of any corrections or amendments 
into the English language together with a statement that the translation 
is accurate.
    (2) The specification (including the abstract and claims) for other 
than reissue applications and reexamination proceedings, and any 
amendments for applications (including reissue applications) and 
reexamination proceedings to the specification, except as provided for 
in Sec. Sec. 1.821 through 1.825, must have:
    (i) Lines that are 1\1/2\ or double spaced;
    (ii) Text written in a nonscript type font (e.g., Arial, Times 
Roman, or Courier, preferably a font size of 12) lettering style having 
capital letters which should be at least 0.3175 cm. (0.125 inch) high, 
but may be no smaller than 0.21 cm. (0.08 inch) high (e.g., a font size 
of 6); and
    (iii) Only a single column of text.
    (3) The claim or claims must commence on a separate physical sheet 
or electronic page (Sec. 1.75(h)).
    (4) The abstract must commence on a separate physical sheet or 
electronic page or be submitted as the first page of the patent in a 
reissue application or reexamination proceeding (Sec. 1.72(b)).
    (5) Other than in a reissue application or reexamination proceeding, 
the pages of the specification including claims and abstract must be 
numbered consecutively, starting with 1, the numbers being centrally 
located above or preferably, below, the text.
    (6) Other than in a reissue application or reexamination proceeding, 
the paragraphs of the specification, other than in the claims or 
abstract, may be numbered at the time the application is filed, and 
should be individually and consecutively numbered using Arabic numerals, 
so as to unambiguously identify each paragraph. The number should 
consist of at least four numerals enclosed in square brackets, including 
leading zeros (e.g., [0001]). The numbers and enclosing brackets should 
appear to the right of the left margin as the first item in each 
paragraph, before the first word of the paragraph, and should

[[Page 48]]

be highlighted in bold. A gap, equivalent to approximately four spaces, 
should follow the number. Nontext elements (e.g., tables, mathematical 
or chemical formulae, chemical structures, and sequence data) are 
considered part of the numbered paragraph around or above the elements, 
and should not be independently numbered. If a nontext element extends 
to the left margin, it should not be numbered as a separate and 
independent paragraph. A list is also treated as part of the paragraph 
around or above the list, and should not be independently numbered. 
Paragraph or section headers (titles), whether abutting the left margin 
or centered on the page, are not considered paragraphs and should not be 
numbered.
    (c)(1) Any interlineation, erasure, cancellation or other alteration 
of the application papers filed must be made before the signing of any 
accompanying oath or declaration pursuant to Sec. 1.63 referring to 
those application papers and should be dated and initialed or signed by 
the applicant on the same sheet of paper. Application papers containing 
alterations made after the signing of an oath or declaration referring 
to those application papers must be supported by a supplemental oath or 
declaration under Sec. 1.67. In either situation, a substitute 
specification (Sec. 1.125) is required if the application papers do not 
comply with paragraphs (a) and (b) of this section.
    (2) After the signing of the oath or declaration referring to the 
application papers, amendments may only be made in the manner provided 
by Sec. 1.121.
    (3) Notwithstanding the provisions of this paragraph, if an oath or 
declaration is a copy of the oath or declaration from a prior 
application, the application for which such copy is submitted may 
contain alterations that do not introduce matter that would have been 
new matter in the prior application.
    (d) A nonprovisional or provisional application may be filed in a 
language other than English.
    (1) Nonprovisional application. If a nonprovisional application is 
filed in a language other than English, an English language translation 
of the non-English language application, a statement that the 
translation is accurate, and the processing fee set forth in Sec. 
1.17(i) are required. If these items are not filed with the application, 
applicant will be notified and given a period of time within which they 
must be filed in order to avoid abandonment.
    (2) Provisional application. If a provisional application is filed 
in a language other than English and the benefit of such provisional 
application is claimed in a nonprovisional application, an English 
language translation of the non-English language provisional application 
will be required in the provisional application. See Sec. 1.78(b).
    (e) Electronic documents that are to become part of the permanent 
United States Patent and Trademark Office records in the file of a 
patent application or reexamination proceeding. (1) The following 
documents may be submitted to the Office on a compact disc in compliance 
with this paragraph:
    (i) A computer program listing (see Sec. 1.96);
    (ii) A ``Sequence Listing'' (submitted under Sec. 1.821(c)); or
    (iii) Any individual table (see Sec. 1.58) if the table is more 
than 50 pages in length, or if the total number of pages of all the 
tables in an application exceeds 100 pages in length, where a table page 
is a page printed on paper in conformance with paragraph (b) of this 
section and Sec. 1.58(c).
    (2) A compact disc as used in this part means a Compact Disc-Read 
Only Memory (CD-ROM) or a Compact Disc-Recordable (CD-R) in compliance 
with this paragraph. A CD-ROM is a ``read-only'' medium on which the 
data is pressed into the disc so that it cannot be changed or erased. A 
CD-R is a ``write once'' medium on which once the data is recorded, it 
is permanent and cannot be changed or erased.
    (3)(i) Each compact disc must conform to the International Standards 
Organization (ISO) 9660 standard, and the contents of each compact disc 
must be in compliance with the American Standard Code for Information 
Interchange (ASCII).
    (ii) Each compact disc must be enclosed in a hard compact disc case 
within an unsealed padded and protective mailing envelope and 
accompanied

[[Page 49]]

by a transmittal letter on paper in accordance with paragraph (a) of 
this section. The transmittal letter must list for each compact disc the 
machine format (e.g., IBM-PC, Macintosh), the operating system 
compatibility (e.g., MS-DOS, MS-Windows, Macintosh, Unix), a list of 
files contained on the compact disc including their names, sizes in 
bytes, and dates of creation, plus any other special information that is 
necessary to identify, maintain, and interpret (e.g., tables in 
landscape orientation should be identified as landscape orientation or 
be identified when inquired about) the information on the compact disc. 
Compact discs submitted to the Office will not be returned to the 
applicant.
    (4) Any compact disc must be submitted in duplicate unless it 
contains only the ``Sequence Listing'' in computer readable form 
required by Sec. 1.821(e). The compact disc and duplicate copy must be 
labeled ``Copy 1'' and ``Copy 2,'' respectively. The transmittal letter 
which accompanies the compact disc must include a statement that the two 
compact discs are identical. In the event that the two compact discs are 
not identical, the Office will use the compact disc labeled ``Copy 1'' 
for further processing. Any amendment to the information on a compact 
disc must be by way of a replacement compact disc in compliance with 
this paragraph containing the substitute information, and must be 
accompanied by a statement that the replacement compact disc contains no 
new matter. The compact disc and copy must be labeled ``COPY 1 
REPLACEMENT MM/DD/YYYY'' (with the month, day and year of creation 
indicated), and ``COPY 2 REPLACEMENT MM/DD/YYYY,'' respectively.
    (5) The specification must contain an incorporation-by-reference of 
the material on the compact disc in a separate paragraph (Sec. 
1.77(b)(5)), identifying each compact disc by the names of the files 
contained on each of the compact discs, their date of creation and their 
sizes in bytes. The Office may require applicant to amend the 
specification to include in the paper portion any part of the 
specification previously submitted on compact disc.
    (6) A compact disc must also be labeled with the following 
information:
    (i) The name of each inventor (if known);
    (ii) Title of the invention;
    (iii) The docket number, or application number if known, used by the 
person filing the application to identify the application; and
    (iv) A creation date of the compact disc.
    (v) If multiple compact discs are submitted, the label shall 
indicate their order (e.g. ``1 of X'').
    (vi) An indication that the disk is ``Copy 1'' or ``Copy 2'' of the 
submission. See paragraph (b)(4) of this section.
    (7) If a file is unreadable on both copies of the disc, the 
unreadable file will be treated as not having been submitted. A file is 
unreadable if, for example, it is of a format that does not comply with 
the requirements of paragraph (e)(3) of this section, it is corrupted by 
a computer virus, or it is written onto a defective compact disc.
    (f)(1) Any sequence listing in an electronic medium in compliance 
with Sec. Sec. 1.52(e) and 1.821(c) or (e), and any computer program 
listing filed in an electronic medium in compliance with Sec. Sec. 
1.52(e) and 1.96, will be excluded when determining the application size 
fee required by Sec. 1.16(s) or Sec. 1.492(j). For purposes of 
determining the application size fee required by Sec. 1.16(s) or Sec. 
1.492(j), for an application the specification and drawings of which, 
excluding any sequence listing in compliance with Sec. 1.821(c) or (e), 
and any computer program listing filed in an electronic medium in 
compliance with Sec. Sec. 1.52(e) and 1.96, are submitted in whole or 
in part on an electronic medium other than the Office electronic filing 
system, each three kilobytes of content submitted on an electronic 
medium shall be counted as a sheet of paper.
    (2) Except as otherwise provided in this paragraph, the paper size 
equivalent of the specification and drawings of an application submitted 
via the Office electronic filing system will be considered to be 
seventy-five percent of the number of sheets of paper present in the 
specification and drawings of the application when entered into the 
Office file wrapper after being rendered

[[Page 50]]

by the Office electronic filing system for purposes of determining the 
application size fee required by Sec. 1.16(s). Any sequence listing in 
compliance with Sec. 1.821(c) or (e), and any computer program listing 
in compliance with Sec. 1.96, submitted via the Office electronic 
filing system will be excluded when determining the application size fee 
required by Sec. 1.16(s) if the listing is submitted in ASCII text as 
part of an associated file.
