A Sequence Listing in XML format is required for patent applications filed on or after July 1, 2022, that disclose nucleotide and/or amino acid sequences as defined in 37 CFR 1.831(b). The MPEP states:
“An application that has a filing date on or after July 1, 2022, will be required to provide a ‘Sequence Listing XML’ in accordance with 37 CFR 1.831 through 1.835 for disclosures of any nucleotide and/or amino acid sequences that meet the definitions of 37 CFR 1.831(a) and (b).”
This requirement applies to all applications with a filing date on or after July 1, 2022, including those claiming benefit or priority to earlier applications.
