What this shows China's Innovation Score is 42.2/100 (top 31% 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 9.2 claims/patent is ABOVE the 8.0 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 Tobacco Hubei Industrial Corporation Limited is a focused PatentsView assignee: 8 CPC subclasses with 33.3% of grants classified under A24F (Smokers' REQUISITES; Match BOXES; Simulated Smoking Devices). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2021. By volume, China sits between China National Digital Switching System Engineering & Technological R&D Center and Cigent Technology, Inc..

China's three-year grant acceleration

China Tobacco Hubei Industrial Corporation Limited shows 4 grants in 2022–2024 against only 1 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.
