What this shows University's Innovation Score is 35.4/100 (top 49% 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 University?

Each dot is one of University’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). University’s own 11.1 claims/patent is at or below the 14.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where University's grants concentrate

University OF Chinese Academy OF Sciences is a focused PatentsView assignee: 12 CPC subclasses with 37.5% of grants classified under C08F (Macromolecular Compounds Obtained BY Reactions Only Involving Carbon-to-carbon Unsaturated Bonds). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2017. By volume, University sits between Universita' Degli Studi DI Trento and UNIVERSITÄT Wien.

University's three-year grant acceleration

University OF Chinese Academy OF Sciences shows 4 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.
