What this shows Qingdao's Innovation Score is 44.6/100 (top 25% 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 13.6 claims/patent is at or below the 18.3 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 Haier Laundry Electric Appliances Co., Ltd is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under D06F (Laundering, Drying, Ironing, Pressing OR Folding Textile Articles). Peak complete grant year is 2024 (7 grants) versus a trough of 1 in 2022. By volume, Qingdao sits between Pvolve, LLC and Qualcomm Connected Experiences, Inc..

Qingdao's three-year grant acceleration

Qingdao Haier Laundry Electric Appliances Co., Ltd shows 10 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.
