What this shows Central's Innovation Score is 42.2/100 (top 31% 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 Central?

Each dot is one of Central’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). Central’s own 8.2 claims/patent is at or below the 12.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Central's grants concentrate

Central China Normal University is a focused PatentsView assignee: 30 CPC subclasses with 36% of grants classified under G09B (Educational OR Demonstration APPLIANCES; Appliances FOR Teaching, OR Communicating With, THE Blind, Deaf OR MUTE; MODELS; PLANETARIA; GLOBES; MAPS; Diagrams). Peak complete grant year is 2021 (5 grants) versus a trough of 1 in 2015. By volume, Central sits between Carl Zeiss Sports Optics GmbH and Clean Diesel Technologies, Inc..

Central's three-year grant acceleration

Central China Normal University shows 8 grants in 2022–2024 against only 8 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.
