CAS News: Numeric Search Property on More STN Databases, and New SciFinder Updates

The Chemical Abstracts Service (CAS), a division of the American Chemical Society, is an authority on chemical information that produces a number of databases (such as CAS REGISTRY, CAplus, CASREACT, CHEMCATS, CHEMLIST, CIN, and MARPAT) which are invaluable resources for prior art searches in the chemistry and pharmaceutical fields. CAS also contributes to the development of large search systems like STN and SciFinder, which patent searchers can use to locate both patent and non-patent literature prior art. Notable updates have been made to both the STN and SciFinder platforms in the last month, including more numeric property search options on STN and the option to group reaction answers by transformation type on SciFinder. SciFinder also now provides more options for sharing SciFinder plans with other users.

Continue reading to learn about recent news on two important prior art search platforms, STN and SciFinder!

STN News

The STN search platform is operated jointly by CAS and FIZ-Karlsruhe, and according to the STN International website (maintained by FIZ-Karlsruhe), the numeric property search (NPS) feature is now available on a number of additional databases on STN.  The press release states:

STN’s unique numeric property search feature (NPS) that allows for searching the numeric values of >30 physical and chemical properties is now available for 11 databases on STN, including Derwent WPI, and many patent full-text files.  Searchable properties and their respective base units comprise data like surface area (m²), molarity, molar concentration (mol/L), density, mass concentration (kg/m³),  molar mass, molecular weight (g/mol), volume (m³) and many more. The system will recognize 90 base units with 1,800 spelling variants.

Currently, databases on STN that include NPS are:

  • 1MOBILITY – Global Mobility Bibliographic database
  • 2MOBILITY – Global Mobility Standards database
  • AEROSPACE – The Aerospace and High Technology database
  • AUPATFULL – Australian patent applications and specifications
  • CANPATFULL – Canadian patent applications and specifications
  • CNFULL – China (CN) Patents Full Text
  • ENCOMPPAT / ENCOMPPAT2 – API EnCompass Patent Database
  • FSTA – Food Science Technology Abstracts
  • METADEX – Metals Abstracts/Alloy Index
  • PCTFULL – Patent Cooperation Treaty database
  • PQSCITECH – ProQuest Science and Technology
  • WPIDS – Derwent World Patents Index Subscriber File
  • WPINDEX – Derwent World Patents Index (Non-subscribers)
  • WPIX – Derwent World Patents Index Subscriber File w. Ext. Abstr.

The Latest SciFinder Updates

The CAS website lists new features available in the latest SciFinder release from September 2012, such as:

  • More Precise Reaction Answer Sets – A new default role (reactant) assigned to substances or fragments to the left of the reaction arrow improves the precision of reaction searches. (The former default role of reactant/reagent is still an option).
  • Group Reaction Answers by Transformation – Evaluate synthesis options and preferred pathways by grouping single-step reaction answers by transformation type.

  • Share SciPlanner™ Plans
    • New Export/Import options that let you share your SciPlanner plans with other SciFinder users.
    • Export a plan locally in the new SciPlanner exchange format (.pkx) and email or share the file with a colleague.
    • Collaborators or colleagues can open your plan using the new Import feature.

Conclusion

These updates to SciFinder and STN are just a few of the new features added to both platforms on a regular basis, and the community report on SciFinder and Major Recent Updates section for the STN System Report are both kept up-to-date with any changes. Continue to monitor the Intellogist System Reports and Community Reports for the latest changes to important prior art search systems.
