What this shows Jianghan's Innovation Score is 44.7/100 (top 25% 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 Jianghan?

Each dot is one of Jianghan’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). Jianghan’s own 7.6 claims/patent is at or below the 10.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Jianghan's grants concentrate

Jianghan University is a focused PatentsView assignee: 12 CPC subclasses with 33.3% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). By volume, Jianghan sits between JCDecaux SA and Johnson Controls AIR Conditioning AND Refrigeration (WUXI) Co., Ltd..

Jianghan's three-year grant acceleration

Jianghan University shows 4 grants in 2022–2024 against only 0 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.
