What this shows Hainan's Innovation Score is 58.5/100 (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 Hainan?

Each dot is one of Hainan’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). Hainan’s own 8.4 claims/patent is at or below the 15.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hainan's grants concentrate

Hainan University is a focused PatentsView assignee: 37 CPC subclasses with 16.1% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2024 (12 grants) versus a trough of 1 in 2016. By volume, Hainan sits between General Electric Deutschland Holding GmbH and Hi-lex Controls, Inc..

Hainan's three-year grant acceleration

Hainan University shows 17 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.
