Database News

DWPI Databases (WPINDEX, WPIDS, WPIX) Enhanced: Numerical Property Search Feature; more than 22 million records.

An enhanced version of Derwent World Patents Index® is now available. For the first time, the new implementation of DWPI on STN offers the patent information searcher a unique numeric property search feature that allows for searching the numeric values of 55 physical and chemical properties, found in the English text of all documents. Searchable properties and their respective base units comprise data like /SAR (Surface Area, m²), /CMOL (Molarity, Molar Concentration, mol/L), /DEN (Density, Mass Concentration, kg/m³), /MFR (Mass Flow Rate, Kg/s), /MM (Molar Mass, Molecular Weight, g/mol), /VOL (Volume, m³) and many more. The system will recognize 55 base units with 1,700 variants.

A search employing numerical property field codes will now be covering data from all fields comprising text in English language. A search for a physical property value will not only find hits in the text showing the exact value but will also include hits where the value is part of a given range (e.g. => s 10/cmol will find "at least 0.008 mol/l" or => s 45/deg will find "0 to 80 degrees"). Open ranges encountered in the database like ‘less than 100 degrees’ have been indexed as well and are routinely searched through. A search for a temperature in Kelvin units will also retrieve documents with the corresponding value (ranges) in Degrees Celsius or Degrees Fahrenheit units.

Search field codes and related text for all physical properties available for numerical property searches have been indexed in the /PHP search field. Details on the newly available search fields and units are listed under HELP NPS.

The database now contains more than 22 million records.

The Eurasian Patent Organization Becomes 63rd Authority on CASM/CAplusSM

CAS enhanced its extensive patent authority coverage in CA/CAplus by adding the Eurasian Patent Organization (EAPO). EAPO (country code EA) is headquartered in Moscow and the 63rd authority covered by CAS.
Eurasian patent documents expand CAS’ already substantial coverage of the world’s major patent authorities. CAS actively continues to expand coverage, particularly from smaller patent authorities which would otherwise be largely inaccessible to many patent searchers.
Coverage of Eurasian kind code B1 is retroactive to February 27, 2007. The B1 kind code covers patents. Eurasian B1 patents are eligible to be covered as basics or added to existing patent families. Approximately 1,700 patents are expected per year including approximately 420 basic patents.

NAPRALERT Updated with More Natural Product Information

Get more information on natural products from the NAPRALERT (NAtural PRoducts ALERT) database on STN with the recent addition of content indexed between 2006 and 2011. NAPRALERT is also now part of the STN Fixed Fee Program.

The NAPRALERT database is a key source for bibliographic information on natural products, including information on the pharmacology, biological activity, taxonomic distribution, chemistry of plant, microbial and animal extracts, as well as ethnomedicine use records. This database is an excellent source for prior art in the areas of traditional medicine and natural products.

For more information about the NAPRALERT database on STN, please refer to the Database Summary Sheet.

Search Tip of the Month

The Value of SUBSET Searching in CAS REGISTRYSM

There are times when a structure search of the full REGISTRY database may contain unanticipated answers. These answers can be removed in many ways.
We show you an effective strategy that uses Molecular Formulas (MF) to create a more focused SUBSET of the REGISTRY database that does not contain the unanticipated answers.

RSS Delivery for STN® Alerts (SDIs) is Now Available on STN

STN alerts (SDIs) can now be delivered by RSS feeds. New RSS alert delivery on STN:

•    Allows you to easily distribute STN alert results throughout your organization to support critical research and business decisions.
•    Supports your workflow by seamlessly integrating with most commercially available RSS readers and custom applications, such as portals.

To set up a new alert for RSS delivery, just enter RSS as the method of delivery during the STN SDI set-up process. Existing alerts can be changed to RSS delivery using the SDI EDIT command. Alerts being delivered by RSS can also be delivered to specific email addresses simultaneously by including these addresses in the Optional Email IDs section of the SDI set-up. At the completion of the SDI set-up process, you will receive the URL for the RSS feed, which can be accessed by any standard RSS reader to display the results.

Add RSS delivery to existing SDI alerts

SDI EDIT provides an easy option to modify existing alerts including delivery method.

1. Enter the database(s) for an existing SDI.
2. To make the change automatically, enter SDI EDIT at the command prompt to assign a line number to each alert parameter.
3. Answer prompts for additional information as needed.
4. Use END to save the changes.
5. If RSS is selected as the delivery option, you will be provided a URL when you save the changes. Use this URL in your RSS reader to subscribe to this alert.
