What this shows Jiangsu's Innovation Score is 36.3/100 (top 47% 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 19.1 claims/patent is ABOVE the 12.2 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 Rotam Chemistry Co., Ltd is a focused PatentsView assignee: 10 CPC subclasses with 100% of grants classified under A01N (Preservation OF Bodies OF Humans OR Animals OR Plants OR Parts Thereof ; Biocides, e.g. AS Disinfectants, AS Pesticides OR AS Herbicides ; Pest Repellants OR ATTRACTANTS; Plant Growth Regulators). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2023. By volume, Jiangsu sits between Jasper Display Corp. and Jingdong Technology Holding Co., Ltd..

Jiangsu's three-year grant acceleration

Jiangsu Rotam Chemistry Co., Ltd shows 5 grants in 2022–2024 against only 7 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.
