What this shows Jiangsu's Innovation Score is 59.2/100 (top 4% 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 13.8 claims/patent is ABOVE the 12.8 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 Contemporary Amperex Technology Limited is a focused PatentsView assignee: 22 CPC subclasses with 93.7% of grants classified under H01M (Processes OR Means, e.g. Batteries, FOR THE Direct Conversion OF Chemical Energy Into Electrical Energy). Peak complete grant year is 2024 (24 grants) versus a trough of 4 in 2021. By volume, Jiangsu sits between Innoscience (ZHUHAI) Technology Co., Ltd. and Nationwide Mutual Insurance Company.

Jiangsu's three-year grant acceleration

Jiangsu Contemporary Amperex Technology Limited shows 46 grants in 2022–2024 against only 4 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.
