What this shows Qingdao's Innovation Score is 37.8/100 (top 42% 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 10.1 claims/patent is at or below the 14.6 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 Haier AIR Conditioner General Corp., Ltd. is a focused PatentsView assignee: 18 CPC subclasses with 86.2% of grants classified under F24F (AIR-CONDITIONING; AIR-HUMIDIFICATION; VENTILATION; USE OF AIR Currents FOR Screening). Peak complete grant year is 2021 (7 grants) versus a trough of 3 in 2020. By volume, Qingdao sits between Protalus, LLC and Raymx Microelectronics, Corp..

Qingdao's three-year grant acceleration

Qingdao Haier AIR Conditioner General Corp., Ltd. shows 12 grants in 2022–2024 against only 16 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.
