What is the significance of WIPO Standard ST.26 in defining amino acids for patent applications?
WIPO Standard ST.26 plays a crucial role in defining amino acids for patent applications, as referenced in MPEP 2412.03(b). The MPEP states: “WIPO Standard ST.26, paragraph 3(a), defines ‘amino acid’ to mean any amino acid that can be represented using any of the symbols shown in Table 3: List of Amino Acid Symbols (reproduced in…

According to MPEP 2412.03(b), peptide nucleic acid (PNA) residues have a special status in amino acid sequence listings. The MPEP clearly states: “A peptide nucleic acid (PNA) residue is not considered an amino acid, but is considered a nucleotide.” This distinction is important for patent applicants and examiners because: PNA residues should not be included…

According to MPEP 2412.03(b), the definition of “amino acid” is broad and inclusive. The section states: “‘Amino acid’ includes any D- or L-amino acid or modified amino acid as defined in paragraph 3(a) of WIPO Standard ST.26.” This definition encompasses not only standard L-amino acids but also D-amino acids and modified amino acids with synthetic…
Read MoreHow are L-amino acids and D-amino acids treated in patent applications?
According to MPEP 2412.03(b), both L-amino acids and D-amino acids are included in the definition of “amino acid” for patent applications. The MPEP states: “Amino acids will be construed as unmodified L-amino acids unless further described in a feature table.” This means that: L-amino acids are the default assumption and do not require special notation.…
