What this shows Jiangsu's Innovation Score is 43.7/100 (top 27% 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 8.9 claims/patent is at or below the 10.1 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 Conant Optical Co., LTD; is a focused PatentsView assignee: 10 CPC subclasses with 85.7% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2023. By volume, Jiangsu sits between JDV Control Valves Co., Ltd. and Jiangsu Zhongtian Technology Co., Ltd..

Jiangsu's three-year grant acceleration

Jiangsu Conant Optical Co., LTD; shows 3 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.
