What this shows China's Innovation Score is 29.4/100 (31st 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 15.5 claims/patent is ABOVE the 10.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where China's grants concentrate

China Automotive Systems, Inc. is a focused PatentsView assignee: 11 CPC subclasses with 66.7% of grants classified under B62D (Motor VEHICLES; Trailers). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2019. By volume, China sits between Chenfeng Optronics Corporation and China Three Gorges Renewables (GROUP) Co., Ltd..

China's three-year grant acceleration

China Automotive Systems, Inc. shows 1 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.
