DWPI Manual Code revision 2018

15. January 2018

From DWPI update 201801 onwards the DWPI Manual Codes will be indexed with the revised 2018 set of codes. The Manual Codes are revised at the start of each year to include new codes suggested by customers as well as the patent analysts at Clarivate Analytics. For the 2018 revision, 36 new Manual Codes have been added, with 15 new CPI (Chemical Patents Index) codes and 21 new codes in the GMPI/EPI (ie General and Mechanical Patents Index and Electrical Engineering Patents Index) areas. The new codes allow newly emerging technologies to be indexed in DWPI, and the revision also includes a number of scope note changes to ensure clarity of the scope of the codes.

Significant enhancements for 2018 include:

  • New code for anti-settling agent (polymer additive) - A08-S09
  • New codes for protein sequencing methods - B11-C08E9 and C11-C08E9
  • New sub-codes and enhancements in W05-D06 (Transmission medium) section with particular regard to ‘Internet-of-Things’ aspects
  • New code for vehicle anti-theft/anti-hacking - X21-X03
