What this shows Zhejiang's Innovation Score is 28.4/100 (27th 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 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 7.8 claims/patent is at or below the 16.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Zhejiang's grants concentrate

Zhejiang Quhua Fluor-chemistry Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 84.6% of grants classified under C07C (Acyclic OR Carbocyclic Compounds). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2016. By volume, Zhejiang sits between Zero Motorcycles, Inc. and Zoll Respicardia, Inc..

Zhejiang's three-year grant acceleration

Zhejiang Quhua Fluor-chemistry Co., Ltd. shows 3 grants in 2022–2024 against only 7 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.
