6 Recent STN Updates, and a New STN Platform!

Every few months, the Intellogist blog checks up on the newest features and coverage available on the STN search platform. The STN platform allows professional patent searchers to hunt for a wide range of relevant prior art by searching through valuable patent and non-patent literature (NPL) databases using a flexible command-line interface. Back in October of 2012, we described the expanded numeric property search feature available on 14 patent and NPL databases on STN. Throughout the remainder of 2012, STN had a number of additional coverage and feature updates, ranging from the addition of a Japanese patent full-text database to the implementation of the new Cooperative Patent Classification (CPC) within the portal. STN also recently announced the beta release of the first version of a new STN platform, which combines command-line searching and an intuitive user interface.

After the jump, learn about six of the most recent major updates to the coverage and features on the STN platform, and read about the release of the new version of STN!

6 Recent Updates to STN

All major recent updates to the STN platform can be found on the Intellogist System Report for STN, and the following updates represent some of the major improvements to the system during November and December 2012:

  • According to the November Issue of STNews:

    In March 2012, CAS announced that the MARPAT database would be enhanced with English-, German- and Japanese-language patents from 1987. The addition of English- and German-language patents for 1987 is now complete. Processing of English- and German-language patents from 1985 and 1986 and Japanese-language patents from 1987 is continuing. We are pleased to report that Markush information from over 2,600 patent publications has been added to date.

  • According to the November Issue of STNews:

    STN now includes JPFULL, the full-text Japanese database of patent applications and patent specifications. Currently JPFULL covers application years 2006 onwards. Historical data will continue to load (one year per week in reverse chronological order) until all records back to 1964 have been incorporated. Once completed, the database will contain approximately 16 million records.

  • According to STN International:

    From week 47/2012 onwards, CPC data are available for new and updated records of the INPADOC databases. Users have full access to all details of the CPC data including CPC codes and attributes. A CPC thesaurus feature supports classification searching, helping users to identify relevant codes and searching the hierarchy of the codes.

    For details and search examples see the INPADOC News 2012/11.

  • According to Information Today:

    FIZ Karlsruhe announced that the complete ReaxysFile is now available on STN. ReaxysFile now contains the full content from Reaxys, a leading source for chemical substance and reaction data produced by Elsevier. […] Information on several million substances has been added, including inorganic substances and substances derived from patents, bringing the database to the same content level as in Reaxys.

  • According to the December 2012 Issue of STNewsline, users can now streamline SDI set up with the new STN command, SDI STANDARD, effective December 9, 2012. The SDI STANDARD command:
    • Increases efficiency by reducing the number of questions to set up an SDI
    • Works with single file and multifile SDIs, including SDI packages
    • Accounts for SDI set-up best practices
    • Maintains flexibility with ability to customize settings using SDI EDIT
    • Reduces STN MAIL charges by changing the default Notifications setting to NO (do not send notifications) from YES
  • According to the CAS website:

    In December, CAS began enhancing its reaction coverage in SciFinder and on STN’s CASREACT® database with the addition of reactions from nearly 900 dissertations published in the Selected Organic Reaction Database (SORD) between 1961-2009.

New STN Platform

The CAS website issued a press release on December 13, 2012 that describes the first version of a new STN platform:

The STN partners, Chemical Abstracts Service (CAS) and FIZ Karlsruhe, are pleased to announce that Version One of the new STN platform is now available in beta for fixed fee customers. This is the first major milestone in a multi-year initiative to create the next generation of STN, the choice of patent experts.

The focus of this first version has been on developing the core search and retrieval system for new STN. This release combines the complete CAS REGISTRY and Chemical Abstracts content along with Thomson Reuters’ Derwent World Patents Index®.[…]

A new approach for STN is to allow organization of work in projects for easy management of search queries and results. New technologies are designed to process broad and complex searches with industry-leading performance. This is vital for patent searchers to keep pace with the continued increase of disclosed research and patent information from around the world.

The new workflow integrates the power of command line with an intuitive user interaction that enables professionals to leverage their expertise and realize instantaneous results. For the first time, text and structures can be combined in a single query to simplify searching for chemical information.

The STN Partners will incorporate additional content and functionality in the new architecture with ongoing versions. Full text patent content will be added throughout 2013. […] The current STN system, including STN Express® and the other STN products will continue to be available and fully supported throughout the development of the new platform.


The STN platform is a crucial tool for professional patent searchers, since it allows users to search a wide range of both patent and NPL databases with the ability to craft complex queries using command-line syntax. The STN platform regularly adds new coverage to existing databases, such as the additional content recently added to MARPAT, CASREACT, and ReaxysFile. The system also occasionally adds new patent full-text databases, like the new JPFULL file that contain full-text Japanese patent records. Besides the new coverage added and recent implementation of the Cooperative Patent Classification (CPC) within the portal, CAS and FIZ-Karlsruhe are also regularly improving the user’s search experience on STN by adding new search and display features (like the new SDI command) and even creating a completely new version of the platform with a streamlined user interface. The roll-out of the new STN platform will be a slow and ongoing process, but it’s exciting to witness the release of a working version of the new platform that includes key prior art content like CAS REGISTRY and DWPI. Hopefully, the new version of the platform will soon be available to all STN users and include expanded coverage.
