(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 (§ 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 or supplemental examination proceeding (§ 1.72(b) ).(5) Other than in a reissue application or a reexamination or supplemental examination 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 or supplemental examination 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 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) Interlineation, erasure, cancellation, or other alteration of the application papers may be made before or after the signing of the inventor's oath or declaration referring to those application papers, provided that the statements in the inventor's oath or declaration pursuant to § 1.63 remain applicable to those application papers. A substitute specification (§ 1.125 ) may be required if the application papers do not comply with paragraphs (a) and (b) of this section.(d) A nonprovisional or provisional application under 35 U.S.C. 111 may be in a language other than English.(1)Nonprovisional application.

If these items are not filed with the application, the 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 under 35 U.S.C. 111(b) is filed in a language other than English, an English language translation of the non-English language provisional application will not be required in the provisional application. See§ 1.78(a) for the requirements for claiming the benefit of such provisional application in a nonprovisional application.(e)Electronic documents submitted on a read-only optical disc that are to become part of the permanent United States Patent and Trademark Office records in the file of a patent application, reexamination, or supplemental examination proceeding.(1) The following documents may be submitted to the Office on a read-only optical disc in compliance with this paragraph (e):(i) A "Computer Program Listing Appendix" (see§ 1.96(c) );(ii) A "Sequence Listing" (submitted under § 1.821(c) in compliance with §§ 1.822 through 1.824 ) or a "Sequence Listing XML" (submitted under § 1.831(a) in compliance with §§ 1.832 through 1.834 ); or(iii) "Large Tables" (see§ 1.58(c) ).(2) Read-only optical disc as used in this part means a finalized disc, in conformance with International Organization for Standardization (ISO) 9660, on which the data is recorded so it is permanent and cannot be changed or erased, and is one of:(i) Compact Disc-Read-Only Memory (CD-ROM) or a Compact Disc-Recordable (CD-R); or(ii) Digital Video Disc-Recordable (DVD-R or DVD+R);(3) Each read-only optical disc must conform to the following requirements: (i) Computer compatibility: PC or Mac®;(ii) Operating system compatibility: MS-DOS®, MS-Windows®, MacOS®, or Unix®/Linux®;(iii) The contents of each read-only optical disc must be in American Standard Code for Information Interchange (ASCII) plain text and if compressed, must be compressed in accordance with § 1.58 for "Large Tables," with § 1.96 for a "Computer Program Listing Appendix," or § 1.824 for a "Sequence Listing" or Computer Readable Form (CRF) of the "Sequence Listing," as applicable; and(iv) The contents of each read-only optical disc for a "Sequence Listing XML" must be in eXtensible Markup Language (XML) file format, and if compressed, must be compressed in accordance with § 1.834 .(4) Each read-only optical disc must be enclosed in a hard case within an unsealed, padded, and protective mailing envelope, and must be accompanied by a transmittal letter in accordance with paragraph (a) of this section, including the following information: (i) First-named inventor (if known);(ii) Title of the invention;(iii) Attorney docket or file reference number (if applicable);(iv) Application number and filing date (if known);(v) The operating system (MS-DOS®, MS-Windows®, Mac OS®, or Unix®/Linux®) used to produce the disc; and(vi) The file(s) contained on the read-only optical disc, including the name of the file, the size of the file in bytes, and the date of creation.(5) Each read-only optical disc must have a label permanently affixed thereto on which the following information has been hand-printed or typed: (i) First-named inventor (if known);(ii) Title of the invention;(iii) Attorney docket or file reference number (if applicable);(iv) Application number and filing date (if known);(v) Date on which the data were recorded on the read-only optical disc; and(vi) Disc order (e.g., "1 of X"), if multiple read-only optical discs are submitted.(6) Read-only optical discs will not be returned to the applicant and may not be retained as part of the patent application file.(7) Any amendment to the information on a read-only optical disc must be by way of a replacement read-only optical disc, in compliance with § 1.58(g) for "Large Tables," § 1.96(c)(5) for a "Computer Program Listing Appendix," § 1.825(b) for a "Sequence Listing" or CRF of a "Sequence Listing," and § 1.835(b) for a "Sequence Listing XML."(8) The specification must contain an incorporation by reference of the material on each read-only optical disc in a separate paragraph (§ 1.77(b)(5) ), identifying the name of each file, their date of creation, and their size in bytes, except for an international application in the international stage. The Office may require the applicant to amend the specification to include the material incorporated by reference.(9) If a file is unreadable, it will be treated as not having been submitted, and a notice will be issued to require a compliant submission.(f)Determining application size fees for applications containing electronic documents submitted on a read-only optical disc or via the USPTO patent electronic filing system -(1)Submission on read-only optical discs. The application size fee required by § 1.16(s) or § 1.492(j) , for an application component submitted in part on a read-only optical disc in compliance with paragraph (e) of this section, shall be determined such that each three kilobytes of content submitted on a read-only optical disc shall be counted as a sheet of paper. Excluded from this determination is any ASCII plain text file or any XML file (as applicable) submitted on a read-only optical disc under paragraph (e) of this section containing:(i) Any "Sequence Listing" or CRF of a "Sequence Listing" in compliance with § 1.821(c) or (e) , or any "Sequence Listing XML" in compliance with § 1.831(a) ; or(ii) Any "Computer Program Listing Appendix" in compliance with § 1.96(c) .(2)Submission via the USPTO patent electronic filing system.
