What this shows China's Innovation Score is 58.0/100 (top 5% 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 8.4 claims/patent is at or below the 13.1 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 Institute of Water Resources and Hydropower Research is a focused PatentsView assignee: 48 CPC subclasses with 23.9% of grants classified under A01G (HORTICULTURE; Cultivation OF Vegetables, Flowers, Rice, Fruit, Vines, Hops OR SEAWEED; FORESTRY; Watering). Peak complete grant year is 2023 (12 grants) versus a trough of 1 in 2018. By volume, China sits between Crisi Medical Systems, Inc. and Danfoss Power Solutions Inc..

China's three-year grant acceleration

China Institute of Water Resources and Hydropower Research shows 25 grants in 2022–2024 against only 11 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.
