What this shows Jiangsu's Innovation Score is 39.8/100 (top 37% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Jiangsu?

Each dot is one of Jiangsu’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Jiangsu’s own 5.6 claims/patent is at or below the 11.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Jiangsu's grants concentrate

Jiangsu Dongcheng Tools Technology Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 21.4% of grants classified under H02P (Control OR Regulation OF Electric Motors, Electric Generators OR Dynamo-electric CONVERTERS; Controlling Transformers, Reactors OR Choke Coils). By volume, Jiangsu sits between Jamf Software, LLC and John Crane Inc..

Jiangsu's three-year grant acceleration

Jiangsu Dongcheng Tools Technology Co., Ltd. shows 5 grants in 2022–2024 against only 0 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
