WIPO Sequence Launched to Support Patent Applicants Filing According to Standard ST.26

The World Intellectual Property Organization (WIPO) has launched new tools WIPO Sequence and WIPO Sequence Validator that support the production and cross-border filing of patent applications generated in the biotechnology sector.

Within the framework of the Committee on WIPO Standards (CWS), the Member States decided that all sequence listings being part of a patent application, filed at national, regional, and international level from 1 January 2022, must be compliant with WIPO Standard ST.26. 

The up-to-date version of ST.26 in English together with its annexes can be found here

Under the CWS guidance and in cooperation with patent offices, the following supporting tools for both applicants and patent offices have been developed:

WIPO Sequence is a global software tool that enables patent applicants to prepare amino acid and nucleotide sequence listings compliant with WIPO Standard ST.26, as part of a national or international patent application.

WIPO Sequence Validator is another tool component that enables patent offices to verify the compliance of filed sequence listing data with WIPO ST.26.


WIPO Sequence
1.0.0 (for applicants)

WIPO Sequence Validator
1.0.0 (for patent offices)

A standalone desktop application available for Windows, Linux, and macOS. A user manual is provided to assist applicants in generating their compliant sequence listings.

A microservice to be incorporated either using a JAR or WAR file in the IT environment of patent offices. An operations manual is provided to assist offices in performing this validation.


Both WIPO Sequence and WIPO Sequence Validator are available for download in English on the WIPO Sequence web page.
