Derwent World Patents Index: Manual Code revision 2020

From DWPI update 2020001 onwards the DWPI Manual Codes will be indexed with the revised 2020 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 Derwent. For the 2020 revision, 59 new Manual Codes have been added, with 39 new CPI (Chemical Patents Index) codes and 20 new codes in the GMPI/EPI (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 2020 include:

• New drug administration codes e.g. Intracardiac (B12-M12Y)
• New drug nano-formulation codes e.g. Nanoparticle (B12-M11Q1)
