New version of WIPO Sequence Suite software released
Tool ensures biological sequence listings comply with mandatory WIPO Standard
A new version of WIPO’s free-of-charge software for preparing and validating sequence listings in patent applications is now available.
The WIPO Sequence Suite ensures that sequence listings comply with WIPO Standard ST.26 – a requirement for PCT applications disclosing amino acid and nucleotide sequences.
Both WIPO Sequence, the desktop application for applicants, and WIPO Sequence Validator, the web service that patent Offices use, have been updated.

Version 3.1.2 is the first production release in three years. Improvements include extended bulk editing, enhanced navigation and warnings for short sequences. Following user feedback, a “hot-fix” patch which resolved reported issues, version 3.1.3, has also been published.
To benefit from improved functionality and ensure you are using the most stable version available, all WIPO Sequence users are strongly encouraged to upgrade to the latest version. It is available for Windows (10/11), Mac and Linux, and the Mac binaries are now signed by WIPO.
Users can download WIPO Sequence from the WIPO website or simply accept the pop-up prompt when you open an earlier version. Contact the International Bureau with any feedback via wiposequence@wipo.int.
