MPEP § 1823.02
*****
Rule 13 ter .1 shall apply mutatis mutandis to the procedure before the International Preliminary Examining Authority.
No designated Office shall require the applicant to furnish to it a sequence listing other than a sequence listing complying with the standard provided for in the Administrative Instructions.
Any nucleotide and/or amino acid sequence listing ("sequence listing"), whether on paper or in electronic form, filed as part of the international application, or furnished together with the international application or subsequently, shall comply with Annex C.
Where an international application discloses one or more nucleotide and/or amino acid sequences, the description must contain a sequence listing complying with the standard specified in the Administrative Instructions. The standard is set forth in detail in Annex C - Standard for the Presentation of Nucleotide and Amino Acid Sequence Listings in International Patent Applications Under the PCT. The standard allows the applicant to draw up a single sequence listing which is acceptable to all receiving Offices, International Searching and Preliminary Examining Authorities for the purposes of the international phase, and to all designated and elected Offices for the purposes of the national phase. The International Searching Authority and the International Preliminary Examining Authority may, in some cases, invite the applicant to furnish a listing complying with that standard. The applicant may also be invited to furnish a listing in an electronic form provided for in the PCT Administrative Instructions. It is advisable for the applicant to submit a listing of the sequence in electronic form, if such a listing is required by the competent International Searching Authority or International Preliminary Examining Authority, together with the international application rather than to wait for an invitation by the International Searching Authority or International Preliminary Examining Authority.
The electronic form is not mandatory in international applications to be searched by the United States International Searching Authority or examined by the United States International Preliminary Examining Authority. However, if an electronic form of a sequence listing is not provided, a search or examination will be performed only to the extent possible in the absence of the electronic form. The U.S. sequence rules ( 37 CFR 1.821 - 1.825 ) and the PCT sequence requirements are substantively consistent. In this regard, full compliance with the requirements of the U.S. rules will ensure compliance with the applicable PCT requirements. For a detailed discussion of the U.S. sequence rules, see MPEP § 2420 - § 2421.04 .
provided that the other elements of the international application are filed as otherwise provided for under the Regulations and these Instructions.
Part 8 of the Administrative Instructions became effective January 11, 2001. Under Administrative Instructions Section 801(a) , applicants may file the nucleotide and/or amino acid sequence listing part of the description of an international application on an electronic medium in electronic form with certain receiving Offices. As of September 6, 2002, Part 8 of the Administrative Instructions was expanded to include tables related to sequence listings. At the present time, the United States Receiving Office (RO/US) has not notified the International Bureau (IB) under Administrative Instructions Section 801(b) that it will be generally accepting the filing of international applications under Administrative Instructions Section 801(a) . The RO/US will, however, accept such applications in a particular case pursuant to Administrative Instructions Section 801(c) , provided that applicant follows the Guidelines set forth below in subsection II. A.
Where sequence listings and/or tables are filed in electronic form under Section 801 (a), the international filing fee payable in respect of that application shall include the following two components:
Applicants will usually achieve a significant fee savings by filing international applications under Administrative Instructions Section 801 (a) in situations where the sequence listings and/or tables consume over four hundred (400) combined pages. The potentially reduced international filing fee described in Administrative Instructions Section 803 is available to applications filed pursuant to the Guidelines below. Applicants who do not wish to file under Administrative Instructions Section 801(a) may submit the sequence listing part and any related tables under conventional filing procedures but will not be eligible for the potentially reduced international filing fee described in Administrative Instructions Section 803 .
When filing an international application under Administrative Instructions Section 801(a) in the RO/US, applicant should not submit a paper copy of the Sequence Listing part and/or tables. If both a sequence listing part and a tables part are filed under Administrative Instructions Section 801 (a), the sequence listing part and the tables part must not be filed on the same electronic medium. With specific regard to tables, only tables which are related to sequence listings, as referred to in PCT Rule 5.2 (a), are covered under Part 8 of the Administrative Instructions. Currently, other types of table data may not be filed on electronic media.
The applicant is required to submit a complete copy of the international application, wherein the sequence listing part and/or tables part of the application is submitted on electronic media rather than on paper. The application is to be accompanied by a transmittal letter entitled "Compact Disc Transmittal Sheet For Submission Of Sequence Listing and/or Tables To the United States Receiving Office Under PCT Administrative Instructions - Part 8."
Applicant shall submit a paper copy of the complete international application, with the exception that the sequence listing part and/or tables part is provided on electronic media rather than on paper. Four (4) copies of the sequence listing part and/or three (3) copies of the tables part are to be included with the application, each copy on an electronic medium or set of electronic media if additional capacity is needed. One copy of the sequence listing part, called the "computer readable form" (CRF) copy required by the Administrative Instructions (see Annex C of the Administrative Instructions, paragraphs 39-46), may be submitted on any acceptable medium under 37 CFR 1.824(c) , although compact disc (CD) media is preferred. All other copies must be submitted only on CD media as specified below:
(1) CD-R
Type: 120mm Compact Disc Recordable
Specification: ISO 9660, 650MB; or
(2) CD-ROM
Type: ISO/IEC 10149:1995, 120mm Compact Disc Read Only Memory
Specification: ISO 9660, 650MB
Each electronic medium shall be enclosed in a hard protective case within a padded envelope. If a sequence listing file is included, the four (4) sequence listing part copies shall be labeled as follows:
If tables file(s) are included, the three (3) tables part copies shall be labeled as follows:
(1) "COPY 1 – TABLES PART"
(2) "COPY 2 – TABLES PART"
(3) "COPY 3 – TABLES PART"
Additionally, the labeling shall contain the following information:
Examples of properly labeled electronic media appear below.
Example of properly labeled electronic medium 

Important Notes :
The electronic medium itself must be neatly labeled with the required information. Labeling of the protective case is recommended, but not required. Sequence listings or tables submitted for correction, rectification, or amendment must satisfy the additional labeling requirements of Administrative Instructions Section 802(d) .
Each CD shall contain either: (1) only a sequence listing part or (2) only a tables part. A sequence listing part and a tables part must not reside together on the same CD. Furthermore, each file in the tables part must have a file name which indicates the name of the table contained therein, e.g., "table-1.txt", "table-2.txt", etc. In addition, no programs or any explanatory files shall appear on any CD.
The sequence listing file and/or tables file(s) must be in compliance with the American Standard Code for Information Interchange (ASCII) and formatted in accordance with Administrative Instructions Annex C, paragraph 41 and Administrative Instructions Annex C- bis . No copy protection or encryption techniques are permitted. File compression is acceptable for the sequence listing part, so long as the compressed file is in a self-extracting format and uses the compression method described in Administrative Instructions Part 7, Annex F, Section 4.1.1. File Compression is not permitted for the tables part.
If applicant desires for an application to be accepted pursuant to Administrative Instructions Section 801(c) , the application must be submitted with a document entitled "Compact Disc Transmittal Sheet For Submission Of Sequence Listing and/or Tables To The United States Receiving Office Under PCT Administrative Instructions - Part 8." This document is available as a PDF sheet that may be downloaded from http://www.uspto.gov/web/offices/pac/dapps/pct/part8translett.pdf. The PDF sheet includes the following information:
Important Note: The "Compact Disc Transmittal Sheet For Submission Of Sequence Listing and/or Tables To The United States Receiving Office Under PCT Administrative Instructions - Part 8" is separate and apart from any other transmittal letter. The Transmittal Sheet requirement cannot be satisfied by incorporating the above information into any other document. A sample copy of a "Compact Disc Transmittal Sheet for Submission of Sequence Listing To the United States Receiving Office Under PCT Administrative Instructions - Part 8" is reproduced on the following page.
