XML Sequence Listing Requirement
Note:
The specification must include an incorporation by reference statement for the XML sequence listing, except during international phase filings via USPTO electronic system or optical disc.

The incorporation by reference statement of the material in an.xml file is required to be part of the specification so it is clear to the Office, the printer, and the public that the application as originally filed includes material on an.xml file. However, for international applications during the international phase, where a “Sequence Listing XML” is submitted via the USPTO patent electronic filing system or on read-only optical disc, no such incorporation by reference statement is required.

Incorporation By Reference of Sequence Listing XML Required

If an applicant includes a 'Sequence Listing XML' but omits the required incorporation by reference paragraph, a pre-examination notice will be issued requiring its inclusion in the substitute specification under 37 CFR 1.125.

If an applicant submits a “Sequence Listing XML” with the complete specification but fails to include the required incorporation by reference paragraph, a notice can be issued by pre-examination requiring the incorporation by reference paragraph in the context of a substitute specification under 37 CFR 1.125. Similarly, the examiner could require applicant to amend the specification to include an incorporation by reference paragraph of the “Sequence Listing XML” file. See also form paragraph 24.24.26.

Incorporation By Reference of Sequence Listing XML Required
Note:
An incorporation by reference statement is needed to ensure the content of the 'Sequence Listing XML' submitted to the USPTO is considered part of the patent disclosure.

Since the “Sequence Listing XML” is not the text of the specification, but rather is sequence data in an XML file format, an incorporation by reference statement is needed to ensure that the content of the “Sequence Listing XML,” submitted to the USPTO as an XML file, is considered part of the disclosure capable of providing 35 U.S.C. 112(a) support for the disclosure and any claims relating to nucleotide and/or amino acid sequences. The incorporation by reference statement identifies: (i) the name of the file; (ii) the date of creation of the file; and (iii) the size of the file in bytes Note that this requirement pertaining to applicant submission of a “Sequence Listing XML” does not apply to a sequence listing that is part of an international application and communicated to the USPTO under PCT Article 20, for a national phase application.
