What this shows China's Innovation Score is 28.9/100 (29th 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 8.8 claims/patent is at or below the 11.8 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 Electronic Technology Corporation, 24th Research Institute is a focused PatentsView assignee: 12 CPC subclasses with 50% of grants classified under H03M (CODING; DECODING; Code Conversion IN General). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2019. By volume, China sits between CCL Secure Pty Ltd and Comsats Institute of Information Technology.

China's three-year grant acceleration

China Electronic Technology Corporation, 24th Research Institute shows 1 grants in 2022–2024 against only 8 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.
