What is the difference between ST.25 and ST.26 for Sequence Listings?
What is the difference between ST.25 and ST.26 for Sequence Listings?
The main differences between ST.25 and ST.26 for Sequence Listings, as implied in MPEP 2415.01, are:
- Format: ST.25 used a text-based format, while ST.26 requires XML format
- Application Date: ST.25 applied to applications filed before July 1, 2022, while ST.26 applies to applications filed on or after July 1, 2022
- Standardization: ST.26 provides a more standardized approach across different patent offices
The MPEP states: “For applications filed on or after July 1, 2022, all sequence listings must be submitted as an XML file named ‘SequenceListing.xml’ in accordance with the ‘Standard for the Presentation of Nucleotide and Amino Acid Sequence Listings in Patent Applications’ (hereinafter ‘ST.26 Standard’).”
This transition from ST.25 to ST.26 represents a significant change in how Sequence Listings are submitted and processed in patent applications.
