What this shows Chinese's Innovation Score is 27.8/100 (25th 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 Chinese?

Each dot is one of Chinese’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). Chinese’s own 9.6 claims/patent is at or below the 12.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Chinese's grants concentrate

Chinese Academy OF Inspection AND Quarantine is a focused PatentsView assignee: 8 CPC subclasses with 87.5% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2021 (3 grants) versus a trough of 2 in 2022. By volume, Chinese sits between China Construction Steel Structure Co., Ltd. and Christiana Care Health System, Inc..

Chinese's three-year grant acceleration

Chinese Academy OF Inspection AND Quarantine shows 2 grants in 2022–2024 against only 3 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.
