What this shows Institute's Innovation Score is 57.6/100 (top 5% 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 11.5 claims/patent is ABOVE the 10.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Institute's grants concentrate

Institute of Optics and Electronics, Chinese Academy of Sciences is a focused PatentsView assignee: 33 CPC subclasses with 40.5% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2024 (8 grants) versus a trough of 1 in 2020. By volume, Institute sits between ILI Technology Corp. and KE M.O.HOUSE Co., Ltd.

Institute's three-year grant acceleration

Institute of Optics and Electronics, Chinese Academy of Sciences shows 16 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.
