What this shows China's Innovation Score is 28.4/100 (27th 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 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 15.0 claims/patent is at or below the 15.9 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 Industries Limited is a focused PatentsView assignee: 8 CPC subclasses with 71.4% of grants classified under A63F (Card, Board, OR Roulette GAMES; Indoor Games Using Small Moving Playing BODIES; Video GAMES; Games NOT Otherwise Provided FOR). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2016. By volume, China sits between Chemex Foundry Solutions GMBH and CHM Industries, Inc..

China's three-year grant acceleration

China Industries Limited shows 1 grants in 2022–2024 against only 3 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.
