What this shows Henan's Innovation Score is 44.9/100 (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 Henan?

Each dot is one of Henan’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). Henan’s own 10.7 claims/patent is at or below the 13.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Henan's grants concentrate

Henan University OF Science AND Technology is a focused PatentsView assignee: 11 CPC subclasses with 33.3% of grants classified under A23N (Machines OR Apparatus FOR Treating Harvested Fruit, Vegetables OR Flower Bulbs IN Bulk, NOT Otherwise Provided FOR; Peeling Vegetables OR Fruit IN BULK; Apparatus FOR Preparing Animal Feeding- Stuffs). By volume, Henan sits between Helena Laboratories Corporation and High Tech Battery Inc..

Henan's three-year grant acceleration

Henan University OF Science AND Technology 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.
