What this shows Qingdao's Innovation Score is 30.3/100 (34th percentile 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 9.2 claims/patent is at or below the 15.3 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 Hater Special Refrigerator Co., Ltd is a focused PatentsView assignee: 10 CPC subclasses with 100% of grants classified under F25D (REFRIGERATORS; Cold ROOMS; ICE-BOXES; Cooling OR Freezing Apparatus NOT Otherwise Provided FOR). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2019. By volume, Qingdao sits between Pypestream Inc. and Qioptiq Photonics GmbH & Co. KG.

Qingdao's three-year grant acceleration

Qingdao Hater Special Refrigerator Co., Ltd shows 3 grants in 2022–2024 against only 4 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.
