What this shows Qingdao's Innovation Score is 42.4/100 (top 31% 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 5.0 claims/patent is at or below the 12.8 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 National Laboratory of Marine Science and Technology Development Center is a focused PatentsView assignee: 14 CPC subclasses with 80% of grants classified under B63B (Ships OR Other Waterborne VESSELS; Equipment FOR Shipping). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2023. By volume, Qingdao sits between Quirky IP Licensing LLC and Quadra Manufacturing, LLC.

Qingdao's three-year grant acceleration

Qingdao National Laboratory of Marine Science and Technology Development Center shows 4 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.
