What is WIPO ST.26 and how does it differ from WIPO ST.25?

WIPO ST.26 is a new standard for the presentation of nucleotide and amino acid sequence listings in patent applications. It replaces WIPO ST.25 for applications filed on or after July 1, 2022. The MPEP states:

“See MPEP §§ 2412 – 2419 for guidance on WIPO ST.26 requirements for applications filed on or after July 1, 2022.”

The main differences include:

  • Format: ST.26 uses XML format, while ST.25 used a text-based format.
  • Scope: ST.26 covers more types of sequences than ST.25.
  • Mandatory inclusion: ST.26 requires the inclusion of more sequences in the listing.

For detailed information on WIPO ST.26 requirements, refer to MPEP §§ 2412 – 2419.
