STN News

Exclusively for the benefit of STN customers, the PPAK field now includes "Claim" tags for substances appearing in the Claims, and the PatentPak Interactive Viewer has been updated to support this enhancement.

Previously available only for CAS Registry(R) and CAplus(R), this valuable option is now also available for Derwent Chemistry Resource(R) (DCR) and the Derwent World Patents Index(R) (WPINDEX/WPIDS/WPIX).

Derwent World Patents Index (DWPI) now features a tremendous increase in the availability of Claims content, providing the opportunity for more comprehensive prior art searching.

Additional authorities will be announced on a quarterly basis.

Emtree is a critical resource for the most updated terminology in biomedicine, pharmacology and medical evices, and is updated three times per year.

The DCR database provides an easier workflow for cross-over into DWPI databases, higher system limits for structure searches, and hit structure highlighting.

A new and enhanced version of the Derwent World Patents Index is now available!

STNext users now have the ability to assign various search assets, including Transcripts, Structures and biosequences, and Scripts including FragCode scripts, into custom-named search Projects.

The new implementation is customized for the STNext platform and provides better recall and precision, via an improved code generation process.

The Get Prior Art Analysis feature is based on the indexing in the patent you found, and on the indexing created by CAS analysts for other patents and non-patent literature included in the CAS databases.
