What this shows Qingdao's Innovation Score is 42.0/100 (top 32% 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 10.3 claims/patent is at or below the 15.4 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 Haier Co., Ltd. is a focused PatentsView assignee: 17 CPC subclasses with 81.5% of grants classified under F25D (REFRIGERATORS; Cold ROOMS; ICE-BOXES; Cooling OR Freezing Apparatus NOT Otherwise Provided FOR). Peak complete grant year is 2022 (13 grants) versus a trough of 3 in 2023. By volume, Qingdao sits between Pretium Packaging, L.L.C. and Resilience Magnum IP, LLC.

Qingdao's three-year grant acceleration

Qingdao Haier Co., Ltd. shows 16 grants in 2022–2024 against only 11 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.
