What this shows Zhejiang's Innovation Score is 40.3/100 (top 36% 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 12.1 claims/patent is at or below the 16.2 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 NHU Co., Ltd. is a focused PatentsView assignee: 25 CPC subclasses with 55.6% of grants classified under C07C (Acyclic OR Carbocyclic Compounds). Peak complete grant year is 2021 (6 grants) versus a trough of 1 in 2017. By volume, Zhejiang sits between XConnect, LLC and nference, Inc..

Zhejiang's three-year grant acceleration

Zhejiang NHU Co., Ltd. shows 7 grants in 2022–2024 against only 12 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.
