What this shows China's Innovation Score is 63.4/100 (top 2% 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 10.4 claims/patent is at or below the 18.0 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 University of Mining and Technology-Beijing is a focused PatentsView assignee: 43 CPC subclasses with 27.9% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2024 (16 grants) versus a trough of 2 in 2017. By volume, China sits between Cardioinsight Technologies Inc. and ExtraHop Networks, Inc..

China's three-year grant acceleration

China University of Mining and Technology-Beijing shows 32 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.
