What this shows Changzhou's Innovation Score is 35.0/100 (49th 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 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 14.8 claims/patent is ABOVE the 10.9 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 Jwei Intelligent Technology Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 100% of grants classified under A24F (Smokers' REQUISITES; Match BOXES; Simulated Smoking Devices). Peak complete grant year is 2021 (7 grants) versus a trough of 1 in 2019. By volume, Changzhou sits between Capsa Solutions Limited and Comigo Ltd..

Changzhou's three-year grant acceleration

Changzhou Jwei Intelligent Technology Co., Ltd. shows 6 grants in 2022–2024 against only 14 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.
