What this shows Qilu's Innovation Score is 62.6/100 (top 2% 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 Qilu?

Each dot is one of Qilu’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). Qilu’s own 9.1 claims/patent is at or below the 16.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Qilu's grant cadence moved

Between 2020–2024, Qilu University of Technology received 24 grants versus 1 in 2015–2019 (+2300% equal-window velocity, top decile growth). Across complete PatentsView years, output peaked in 2023 at 11 grants and bottomed in 2019 at 1. Lead class D21H accounts for 18.2% of the portfolio across 50 subclasses. Volume neighbours: QBase, LLC (#9,591) and Rieke LLC (#9,599).

Qilu's three-year grant acceleration

Qilu University of Technology shows 23 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.
