What this shows Zhejiang's Innovation Score is 48.6/100 (top 16% 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 Zhejiang?

Each dot is one of Zhejiang’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). Zhejiang’s own 13.8 claims/patent is ABOVE the 8.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Zhejiang's grants concentrate

Zhejiang Liankong Technologies Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 25% of grants classified under B60K (Arrangement OR Mounting OF Propulsion Units OR OF Transmissions IN VEHICLES; Arrangement OR Mounting OF Plural Diverse Prime-movers IN VEHICLES; Auxiliary Drives FOR VEHICLES; Instrumentation OR Dashb). By volume, Zhejiang sits between Zhejiang A & F University and Zhengzhou University OF Light Industry.

Zhejiang's three-year grant acceleration

Zhejiang Liankong Technologies Co., Ltd. shows 3 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.
