What this shows Anhui's Innovation Score is 59.4/100 (top 4% 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 Anhui?

Each dot is one of Anhui’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). Anhui’s own 7.5 claims/patent is at or below the 18.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Anhui's grants concentrate

Anhui University OF Science AND Technology is a focused PatentsView assignee: 41 CPC subclasses with 32.4% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2024 (11 grants) versus a trough of 1 in 2017. By volume, Anhui sits between ALI S.P.A.—CARPIGIANI Group and ASM America, Inc..

Anhui's three-year grant acceleration

Anhui University OF Science AND Technology shows 22 grants in 2022–2024 against only 7 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.
