What this shows Qingdao's Innovation Score is 45.6/100 (top 23% 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 Qingdao?

Each dot is one of Qingdao’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). Qingdao’s own 4.7 claims/patent is at or below the 16.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Qingdao's grants concentrate

Qingdao Agricultural University is a focused PatentsView assignee: 34 CPC subclasses with 33.3% of grants classified under Y02A (Technologies FOR Adaptation TO Climate Change). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2020. By volume, Qingdao sits between Puratos N.V. and Rational Aktiengesellschaft.

Qingdao's three-year grant acceleration

Qingdao Agricultural University shows 9 grants in 2022–2024 against only 5 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.
