What this shows Zhejiang's Innovation Score is 37.7/100 (top 43% 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 10.0 claims/patent is at or below the 12.2 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 Medicine Co., Ltd. Xinchang Pharmaceutical Factory is a focused PatentsView assignee: 23 CPC subclasses with 53.8% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2018 (7 grants) versus a trough of 2 in 2017. By volume, Zhejiang sits between Zest IP Holdings, LLC and Agena Bioscience, Inc..

Zhejiang's three-year grant acceleration

Zhejiang Medicine Co., Ltd. Xinchang Pharmaceutical Factory shows 2 grants in 2022–2024 against only 4 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.
