DWPI: Latest Manual Code Revision goes live

07. January 2016

The Derwent World Patents Index® (DWPISM) manual coding system annual revision for 2015 is now complete and is being used by the editorial teams to code records appearing in the database from DWPI Update 201601 onward. The editorial team consistently applies DWPI manual codes to new inventions across all 50 authorities covered in the database. Since the coding highlights the novel technical aspects of the invention as well as the application(s), it is extremely useful to improve the precision and recall of searches and the subsequent analysis of result sets.

As with previous revisions, the coding has been updated to:

  • Reflect changes in technology
  • Take into account suggestions for improvements
  • Enhance code descriptions and scope notes to improve the consistency of code application by the editorial teams and understanding of what each code covers.
  • 220 changes have been made to DWPI codes, including 176 new codes, as well as the updating of existing Titles, Scope notes and/or Search terms.

Significant enhancements include:

  • Introduction of codes for Biosimilars
  • Expansion of coding for specific Immunoglobulins and other antibody types
  • Recasting and expansion of Diagnostics sections B/C 12-K04A (moved to new section B/C12-K04G to facilitate a better coding structure and additional codes).
  • 22 new codes added to the X25-A08 3D printing / additive manufacturing hierarchy

The Coding Manuals and reference guides on the Thomson Reuters website have all been updated to include the changes. These resources are available at:
