How does WIPO Standard ST.26 differ from WIPO Standard ST.25 for sequence listings?

WIPO Standard ST.26 and ST.25 are different standards for sequence listings in patent applications:

• ST.26 applies to applications filed on or after July 1, 2022.
• ST.25 applies to applications filed before July 1, 2022.
• ST.26 requires sequence listings in XML format, while ST.25 uses a different format.
• ST.26 allows for a single, internationally acceptable sequence listing across WIPO member states.

The MPEP states: WIPO Standard ST.26 permits applicants to submit a single, internationally acceptable sequence listing in a language-neutral format using specified International Nucleotide Sequence Database Collaboration (INSDC) identifiers in international applications filed under the Patent Cooperation Treaty (PCT) and in national and regional applications in the intellectual property offices (IPOs) of WIPO member states.
