In March 2016 the World Intellectual Property Organization’s (WIPO) Committee on WIPO Standards (CWS) adopted a new standard for Sequence Listings, ST.26. IP Australia, under the Patent Cooperation Treaty (PCT), has implemented the new standard as it came into effect by CWS, thus we now accept Sequence Listing Patent applications in this standard.
IP Australia sought public comment on the new WIPO Standard for Sequence Listing.
Previously, patent specifications in Sequence Listings were made in ST.25, a text format which can be hard to validate. The revised standard, ST.26, has enhanced the scope of current standards and better supports digital transaction activities.
Summary of the main differences between ST.25 and ST.26 are as follows:
- ST.25 supports text format, ST.26 supports Extensible Markup Language (XML) format.
ST.25 accepts sequence listings in electronic form as well as on paper whereas ST.26 accepts sequence listings in electronic form (XML file) only.
- The scope of new standard ST.26 is wider than ST.25 as it is filing route neutral, that is, it does not contain any processing arrangements specific to national, regional or international applications but, in its entirety, is applicable to all patent applications, be they national, regional or international.
