What this shows Central's Innovation Score is 38.4/100 (top 41% 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 10.8 claims/patent is at or below the 11.7 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 South University OF Forestry AND Technology is a focused PatentsView assignee: 24 CPC subclasses with 22.2% of grants classified under A01G (HORTICULTURE; Cultivation OF Vegetables, Flowers, Rice, Fruit, Vines, Hops OR SEAWEED; FORESTRY; Watering). Peak complete grant year is 2021 (4 grants) versus a trough of 2 in 2023. By volume, Central sits between Celon Pharma S.A. and Cevec Pharmaceuticals GmbH.

Central's three-year grant acceleration

Central South University OF Forestry AND Technology shows 4 grants in 2022–2024 against only 4 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.
