What this shows Institute's Innovation Score is 33.9/100 (46th 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 Institute?

Each dot is one of Institute’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). Institute’s own 12.5 claims/patent is at or below the 15.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Institute's grants concentrate

Institute of Electrical Engineering, Chinese Academy of Sciences is a focused PatentsView assignee: 16 CPC subclasses with 33.3% of grants classified under G01R (Measuring Electric VARIABLES; Measuring Magnetic Variables). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2018. By volume, Institute sits between Innovation Hammer LLC and Interlight Optotech Corporation.

Institute's three-year grant acceleration

Institute of Electrical Engineering, Chinese Academy of Sciences shows 2 grants in 2022–2024 against only 5 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.
