What this shows China's Innovation Score is 37.4/100 (top 44% 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 China?

Each dot is one of China’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). China’s own 7.0 claims/patent is at or below the 11.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where China's grants concentrate

China Pharmaceutical University is a focused PatentsView assignee: 13 CPC subclasses with 88% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2017. By volume, China sits between C. Rob. Hammerstein GmbH & Co. KG and Clearwire IP Holdings L.L.C..

China's three-year grant acceleration

China Pharmaceutical University shows 11 grants in 2022–2024 against only 8 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.
