What this shows China's Innovation Score is 41.2/100 (top 34% 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 10.5 claims/patent is at or below the 12.1 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 Electric Power Research Institute is a focused PatentsView assignee: 28 CPC subclasses with 42.9% of grants classified under H02J (Circuit Arrangements OR Systems FOR Supplying OR Distributing Electric POWER; Systems FOR Storing Electric Energy). Peak complete grant year is 2020 (9 grants) versus a trough of 1 in 2015. By volume, China sits between Camtek Ltd. and Code Systems Corporation.

China's three-year grant acceleration

China Electric Power Research Institute shows 8 grants in 2022–2024 against only 14 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.
