What this shows Zhejiang's Innovation Score is 29.2/100 (30th 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 11.5 claims/patent is ABOVE the 1.0 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 Medicine Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 50% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2016. By volume, Zhejiang sits between ZeroWheel, LLC and Zhonghao Chenguang Research Institute of Chemiccal Industry Company Limited.

Zhejiang's three-year grant acceleration

Zhejiang Medicine Co., Ltd. shows 1 grants in 2022–2024 against only 2 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.
