What this shows Jiangsu's Innovation Score is 51.7/100 (top 11% 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 16.8 claims/patent is ABOVE the 4.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Jiangsu's grants concentrate

Jiangsu Kangrui New Material Technology Co., Ltd. is a focused PatentsView assignee: 15 CPC subclasses with 66.7% of grants classified under B24B (Machines, Devices, OR Processes FOR Grinding OR Polishing ; Dressing OR Conditioning OF Abrading SURFACES; Feeding OF Grinding, Polishing, OR Lapping Agents). Peak complete grant year is 2024 (7 grants) versus a trough of 1 in 2021. By volume, Jiangsu sits between Jenoptik Advanced Systems GmbH and Jsyard Home Technology Co., Ltd.

Jiangsu's three-year grant acceleration

Jiangsu Kangrui New Material Technology Co., Ltd. shows 7 grants in 2022–2024 against only 1 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.
