What this shows Chinese's Innovation Score is 32.0/100 (40th 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 12.0 claims/patent is at or below the 16.1 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 Sciences, Institute of Geology and Geophysics is a focused PatentsView assignee: 11 CPC subclasses with 62.5% of grants classified under B81B (Microstructural Devices OR Systems, e.g. Micromechanical Devices). Peak complete grant year is 2017 (5 grants) versus a trough of 1 in 2015. By volume, Chinese sits between ChargEdge, Inc. and Cloud Light Technology Limited.

Chinese's three-year grant acceleration

Chinese Academy of Sciences, Institute of Geology and Geophysics shows 3 grants in 2022–2024 against only 6 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.
