Derwent World Patents Index - Manual Code revision 2022

From DWPI update 2022001 onwards the DWPI Manual Codes will be indexed with the revised 2022 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. For the 2022 revision, 79 new Manual Codes have been added, with 65 new CPI (Chemical Patents Index) codes and 14 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.
