What this shows Donghua's Innovation Score is 52.7/100 (top 10% 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 Donghua?

Each dot is one of Donghua’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). Donghua’s own 8.1 claims/patent is ABOVE the 7.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Donghua's grants concentrate

Donghua University is a focused PatentsView assignee: 28 CPC subclasses with 61.5% of grants classified under D10B (Indexing Scheme Associated With Sublasses OF Section D, Relating TO Textiles). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2017. By volume, Donghua sits between Discord Inc. and DS Fashion Group.

Donghua's three-year grant acceleration

Donghua University shows 6 grants in 2022–2024 against only 2 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.
