Requirement for Sequence Listing XML
Note:
If pre-examination staff identifies that a ‘Sequence Listing XML’ is required but missing or non-compliant, they will issue a notice to the applicant indicating the deficiencies.

Part of the pre-examination process as well as initial review by the examiner involves identifying whether an application that discloses nucleotide and/or amino acid sequences requires submission of a “Sequence Listing XML,” and if so, if it contains a compliant “Sequence Listing XML.” If pre-examination staff identifies that a “Sequence Listing XML” is required but missing or that compliance with 37 CFR 1.831 – 1.835 is lacking, a notice indicating the deficiencies will be issued to the applicant. Similarly, upon having a new application placed on the examiner’s docket, the examiner can assess whether a disclosure of nucleotide and/or amino acid sequences in the application requires a “Sequence Listing XML” to be submitted where one has not been submitted. The examiner can identify the requirement for a “Sequence Listing XML” on an “OPAP Routing Sheet” (Document Code “SEQREQ”) and return the application to pre-examination for the mailing of a notice indicating the deficiencies.

Requirement for Initial Sequence Listing XML
Note:
Applicants must submit a compliant XML file, amend the specification to reference it, identify disclosed sequences, and confirm no new matter is introduced.
Applicant's response to a notice or an Office Action requiring an initial “Sequence Listing XML” would involve providing the following:
  • (1) A compliant “Sequence Listing XML” submitted as an XML file using either the USPTO patent electronic filing system (currently, XML files can only be submitted via Patent Center) or a read-only optical disc that is mailed or hand-delivered into the Office. If the size of “Sequence Listing XML” file exceeds the upload limit of Patent Center, then it must be submitted on read-only optical disc. (37 CFR 1.835(a)(1));
  • (2) An amendment to the specification to incorporate by reference the material in the “Sequence Listing XML” by reciting in a separate paragraph of the specification the name of the file, the date of creation, and the size of the file in bytes (37 CFR 1.835(a)(2) and 37 CFR 1.835(c));
  • (3) A statement identifying the basis for the added “Sequence Listing XML,” which would include, e.g., paragraphs of the originally filed specification or sheets of the drawings where a sequence is disclosed, identifying each sequence that is part of the “Sequence Listing XML” (37 CFR 1.835(a)(3)); and
  • (4) A statement that no new matter is introduced by the content of the “Sequence Listing XML” (37 CFR 1.835(a)(4)).

Note:
The rule requires that no new matter be introduced through the content of the 'Sequence Listing XML' when submitting it to comply with Office requirements.

Applicant's response to a notice or an Office Action requiring an initial “Sequence Listing XML” would involve providing the following:

(4) A statement that no new matter is introduced by the content of the “Sequence Listing XML” (37 CFR 1.835(a)(4)).
