What are the requirements for representing amino acid sequences in patent applications?

The requirements for representing amino acid sequences in patent applications are detailed in MPEP 2421.02. Key points include:

  • Amino acid sequences must be represented using the standard three-letter or single-letter amino acid codes.
  • Sequences with 4 or more amino acids must be included in the sequence listing.
  • Each sequence must be assigned a unique SEQ ID NO.
  • D-amino acids should be represented in the sequence by describing the amino acid as the D-isomer.

The MPEP specifically states: “Unbranched nucleotide sequences of 10 or more residues and unbranched, non-D amino acid sequences of 4 or more residues, provided that there are at least 10 nucleotides or 4 amino acids within the defined sequence, are required to be included in the sequence listing.” This requirement ensures standardization and clarity in the presentation of amino acid sequence information in patent applications.
