What this shows Dalian's Innovation Score is 37.7/100 (top 43% 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 6.8 claims/patent is at or below the 8.9 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 University is a focused PatentsView assignee: 13 CPC subclasses with 37.5% of grants classified under H04L (Transmission OF Digital Information, e.g. Telegraphic Communication). By volume, Dalian sits between D. LA Porte SÖHNE GMBH and Datafeel Inc..

Dalian's three-year grant acceleration

Dalian University shows 2 grants in 2022–2024 against only 1 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.
