What this shows Jiangsu's Innovation Score is 27.1/100 (22nd percentile 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 5.1 claims/patent is at or below the 8.3 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 Youmay Electric Appliance Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 28.6% of grants classified under F04D (Non-positive-displacement Pumps). Peak complete grant year is 2021 (3 grants) versus a trough of 2 in 2023. By volume, Jiangsu sits between Jhih Huei Trading Co., Ltd. and JIN SUN GEE Plastics Co., Ltd..

Jiangsu's three-year grant acceleration

Jiangsu Youmay Electric Appliance Co., Ltd. shows 4 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.
