DWPI Manual Code revision 2019

04. January 2019

From DWPI update 201901 onwards the DWPI Manual Codes will be indexed with the revised 2019 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 2019 revision, 37 new Manual Codes have been added, with 28 new CPI (Chemical Patents Index) codes and 9 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.

Significant revisions for 2019 include:

  • Biocatalysts – New, more precise code (N05-E04)
  • Electronic finance (T05)/ transmission systems (W05)
  • updated numerous code descriptions
  • New code for Pharmaceutical dispensing and delivery systems (S05-M05)
  • New codes for sequencing methods (B11-C08F7, plus subdivisions for DNA etc)
  • X15 hierarchy extended to include further details of renewable energy systems (e.g. X15-A15 – Manufacture, maintenance etc. of solar power systems)
