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…
