Derwent WPI: The New Cooperative Patent Classification Is Now Available
The Cooperative Patent Classification (CPC) is a new patent classification system jointly developed and maintained by the European Patent Office (EPO) and the US Patent and Trademark Office (USPTO). The Derwent World Patents Index® (DWPISM) accommodates CPC data from two different sources including CPCs published by the European Patent Office in DOCDB and CPCs published by the USPTO on the front page of the original US patent documents. CPC information is currently provided for updated DWPI records from Derwent update (/DW) 18/2013 onwards (14th of March). In addition, new records cover the CPC published by the USPTO. The CPC backfile is expected to be loaded in June 2013 providing CPC data published to the third week of January 2013. Later, the standard quarterly reclassification updates include CPC data for new patent publications and CPC revisions, beginning in July 2013. The European patent classifications ECLA and ICO as well as the US Patent Classification will be retained as historical classification data in DWPI.

STN Updated to Reflect Streamlining of CAS Roles
Effective May 18, 2013, the list of CAS Roles has been streamlined to increase clarity and search efficiency. Selected roles no longer in use have been replaced in the CASM/CAplusSM backfile indexing with the appropriate broader term from the role hierarchy. The CAS Roles Thesaurus on STN has also been updated to reflect this change and an STN search edit has been implemented to ensure continued comprehensive retrieval by automatically updating users' search queries with the current applicable role.
Roles and super roles are used in the CA/CAplus family of files to allow searching for precise information on substances. For example, searching:
S SIMVASTATIN/CT (L) THU/RL
restricts retrieval to documents focused on THerapeutic Uses of simvastatin. Roles are assigned to every indexed substance and to controlled index terms for classes of compounds.
For documentation of current roles, super roles and their meanings, see our updated Quick Reference Card.

STN Adds Indian Patent Full Text File - INFULL
Effective May 28, 2013, INFULL adds the full-text of Indian patent applications and granted patents in English to STN. The Indian Patent Office (Intellectual Property India) published about 30,000 documents annually in recent years.
The records of the database contain bibliographic data including patent applicant and inventor, patent number, application, priority, and related application data, IPC, CPC, EPC, and ICO classification codes, abstract, and the full text of descriptions and claims. Abstracts are either original or taken from equivalent documents (according to DOCDB) if available. If original description and claims are not present in sufficient quality or are not available, they are taken from equivalent documents as well. The content of equivalent descriptions and claims are indexed as usual in the fields DETD, CLM, and BI. The search fields are indexed as usual as DETD and CLM in the field availability (FA) and additionally as DETD.EQ and CLM.EQ. In this way, the equivalent description and claims are searchable separately.
Each database record contains all documents published for one application, displayed in order of appearance. Family display formats from the INPADOCDB database up to 2004 are available too. Online thesauri for the International Patent Classification (/IPC), Cooperative Patent Classification (/CPC) and European Patent Classification (/EPC and /ICO) are searchable. Numeric values of 55 physical and chemical properties (/PHP) in about 1,800 unit variants are searchable in all full-text fields.
The INFULL file contains over 440,000 records and about 120,000 images from 1912 onwards. About 500 documents are published each week, which are available in INFULL about a week after publication with the complete content.
For additional information about this new databases, refer to the STN Database Summary Sheet or STN Guide (=> s INFULL/DBN).
