1. Description of the area to be revised:
H02J17/00
Circuit arrangements or systems for wireless supply or distribution of electric power
2. The request will be evaluated according to the following criteria:
Reasons for revision a Subdivision of IPC groups having an excessive file size b High rate of growth of the PCT minimum documentation
Av.- file size
> 9,900
Growth rate
> c Due to changes in technology the classification structure has become inefficient for searching. A gain in efficiency is expected with the proposed new scheme d Clarification of wordings in order to improve consistency in classifying or to avoid overlap with other places of the IPC e A high number of searches are executed in the technical field (i.e. a high number of patent applications or a high number of searches for other purposes) f New technology not specifically covered in the current IPC patent appl. other searches
Factors influencing the cost and effort of the project g Appropriate subdivisions already exist in a local classification scheme and can be easily brought into the IPC

Additional Remarks
This revision request is based on the result of IP5 GCI project F035.
The five offices determined that each subgroup should be hierarchically developed by establishing numbers of more detailed subdivisions in order. It is aimed at improving effectiveness of the IPC as a search tool since, among group H02J17/00, each subgroup contains on average a large number of
9,900 patent documents.
The proposed scheme and RCL presented in this report, agreed upon by the five offices after review at the F035, intend to introduce the FI ’s groups H02J17/00.

Note(s)
1. In this group, multi-aspect classification is applied, so that subject matter characterised by aspects covered by more than one of its subgroups should be classified in each of those subgroups.
2. When classifying in this group, the specific technology used for the wireless power transmission is classified in the relevant group of H02J 17/05 - H02J 17/30, while arrangements or functional aspects are classified in groups H02J 17/40 - H02J
17/90.
