What this shows Jiangsu's Innovation Score is 40.4/100 (top 36% 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 11.4 claims/patent is ABOVE the 11.0 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 Shemar Electric Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 71.4% of grants classified under H01B (CABLES; CONDUCTORS; INSULATORS; Selection OF Materials FOR Their Conductive, Insulating OR Dielectric Properties). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2017. By volume, Jiangsu sits between Japan Radio Co., Ltd. and Japan Capacitor Industrial Co., Ltd..

Jiangsu's three-year grant acceleration

Jiangsu Shemar Electric Co., Ltd. shows 7 grants in 2022–2024 against only 3 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.
