The STN AnaVist Database Summary Sheet for WPINDEX includes the following:
Description
Derwent World Patents Index (DWPI non-Subscriber file) provides information on patent publications from the 41 most important patent issuing authorities of the world.
Each record in the database describes a patent family, starting with the new invention (Basic Patent) and adding information about the same invention issued in other countries (Equivalents). Two levels of data are available within the database for each record. The Invention Level comprises bibliographic data and Thomson Scientific value-added titles, abstracts, general and where appropriate, in-depth chemical and electrical indexing. Thomson Scientific applies various algorithms to collate and deduplicate the data from the individual member patents of the patent family when creating this 'Patent Family' (Invention Level) view. The Member Patent Level (Publication Level) allows users to search and display bibliographic data and general indexing information associated with individual documents that make up the patent family Invention Level. Users can do very specific searching of individual documents. Additional first level data elements and agent information are also present at the Member Patent Level. The Invention and Member Patent Levels can be searched individually or in combination.
Electrical and engineering drawings may be present in records dating back to 1988, and chemical structure drawings may be present in records dating back to 1992. Beginning with Update 1999-08, two Thomson Scientific value-added content fields, Novelty (NOV) and Technology Focus (TECH), were added. The Novelty field outlines the novelty of the invention. The Technology Focus provides further information to the Basic (Alert) Abstract (AB), describing the invention from different technological viewpoints, thus helping to present the practical scientific content of the patent in a more easily understood form.
The Chemistry Resource (DCR), available beginning with Update 1999-16, offers structure searching and various other substance identification and indexing fields. DCR search results are linked to bibliographic records.
Online thesauri are available in the IPC (/IPC), Manual Code (/MC), and Title Terms (/TT) fields. There is a thesaurus-like feature in the Compound Number (/DCN), Derwent Registry Number (/DRN), and Patent Assignee Code (/PACO) fields.
LWPI is the low cost companion training file for the WPINDEX/WPIDS/WPIX files (images included). Fast-alerting access to newly-published patent documentation is available in Derwent World Patents Index First View (SM) - file WPIFV.
Left truncation and simultaneous left and right truncation (SLART) are available in many fields. See SEARCH AND DISPLAY FIELDS.
In this file, you can SET ABBREVIATONS ON and have abbreviations for certain terms automatically added to the search profile. This file participates in the STN Information Keep & Share Program. Enter HELP SHARETERMS for more information. This file may be used in a multifile SDI.
