What this shows Dalian's Innovation Score is 47.1/100 (top 19% 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 Dalian?

Each dot is one of Dalian’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). Dalian’s own 5.7 claims/patent is at or below the 8.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dalian's grants concentrate

Dalian Maritime University is a focused PatentsView assignee: 19 CPC subclasses with 20% of grants classified under G06T (Image Data Processing OR Generation, IN General). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2017. By volume, Dalian sits between Dyve Biosciences, Inc. and Danfoss Drives A/S.

Dalian's three-year grant acceleration

Dalian Maritime University shows 8 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.
