What this shows Qingdao's Innovation Score is 51.9/100 (top 11% 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 19.4 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 Air-conditioning Electronic Co., Ltd. is a focused PatentsView assignee: 16 CPC subclasses with 83.3% of grants classified under F24F (AIR-CONDITIONING; AIR-HUMIDIFICATION; VENTILATION; USE OF AIR Currents FOR Screening). Peak complete grant year is 2022 (17 grants) versus a trough of 2 in 2021. By volume, Qingdao sits between Ppip, LLC and Ruag Ammotec GmbH.

Qingdao's three-year grant acceleration

Qingdao Haier Air-conditioning Electronic Co., Ltd. shows 33 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.
