What this shows Changzhou's Innovation Score is 46.1/100 (top 22% 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 Changzhou?

Each dot is one of Changzhou’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). Changzhou’s own 15.3 claims/patent is ABOVE the 13.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Changzhou's grants concentrate

Changzhou Mingseal Robot Technology Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 75% of grants classified under B05B (Spraying APPARATUS; Atomising APPARATUS; Nozzles). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2021. By volume, Changzhou sits between Ceramica Malpesa, S.A. and Chengdu Aircraft Industrial (GROUP) Co., Ltd..

Changzhou's three-year grant acceleration

Changzhou Mingseal Robot Technology Co., Ltd. shows 7 grants in 2022–2024 against only 1 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.
