How does the WIPO Standard ST.26 affect sequence listing submissions for patent applications?

This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

The WIPO Standard ST.26 has a significant impact on sequence listing submissions for patent applications:

• It applies to all patent applications with a filing date on or after July 1, 2022.
• Sequence listings must be submitted in XML format compliant with ST.26.
• It replaces the previous WIPO Standard ST.25 for these applications.
• The standard aims to harmonize sequence listing submissions across patent offices worldwide.

According to MPEP 2422.03: “For applications filed on or after July 1, 2022, a “Sequence Listing” must be submitted as an XML file compliant with WIPO Standard ST.26.” This change ensures consistency and improves the quality of sequence data in patent applications globally.
