What this shows Qingdao's Innovation Score is 45.4/100 (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 8.9 claims/patent is at or below the 16.6 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 Institute of Marine Geology is a focused PatentsView assignee: 11 CPC subclasses with 30% of grants classified under E21C (Mining OR Quarrying). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2018. By volume, Qingdao sits between Quanticel Pharmaceuticals, Inc. and Queen Mary & Westfield College, University of London.

Qingdao's three-year grant acceleration

Qingdao Institute of Marine Geology shows 6 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.
