What is WIPO Standard ST.26 and how does it relate to patent applications?
WIPO Standard ST.26 is an international standard that defines the format and content requirements for nucleotide and amino acid sequence listings in patent applications. It was developed by the World Intellectual Property Organization (WIPO) to standardize the presentation of sequence information across different patent offices globally.
According to MPEP 2412.02(a), WIPO Standard ST.26 is incorporated by reference in USPTO regulations:
“…where the residues are represented in the manner as defined in paragraph 3(c)(i) or (ii) of WIPO Standard ST.26 (incorporated by reference, see § 1.839).”
This standard provides specific guidelines on how to enumerate residues in sequence listings, ensuring consistency and facilitating the exchange of sequence data between patent offices and public sequence databases. It applies to patent applications filed on or after July 1, 2022, that contain nucleotide and/or amino acid sequence disclosures.
