What this shows Zhejiang's Innovation Score is 30.1/100 (33rd 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 14.2 claims/patent is ABOVE the 9.2 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 Ausun Pharmaceutical Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 75% of grants classified under C07C (Acyclic OR Carbocyclic Compounds). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2016. By volume, Zhejiang sits between Zeng Hsing Industrial Co., Ltd. and Zkteco Co., Ltd..

Zhejiang's three-year grant acceleration

Zhejiang Ausun Pharmaceutical Co., Ltd. shows 3 grants in 2022–2024 against only 6 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.
