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 1.0 claims/patent is at or below the 11.0 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 Wellspring PET Articles Co., Ltd. is a focused PatentsView assignee: 0 CPC subclasses . By volume, Jiangsu sits between Jiangsu Cherrity Optronics Co., Ltd. and Joi Scientific, Inc..
Jiangsu's three-year grant acceleration
Jiangsu Wellspring PET Articles Co., Ltd. shows 4 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.
