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 10.8 claims/patent is ABOVE the 7.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Qingdao's grants concentrate

Qingdao Jiaonan Haier Washing Machine Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under D06F (Laundering, Drying, Ironing, Pressing OR Folding Textile Articles). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2018. By volume, Qingdao sits between Qianjiang Yongan Phamaceutical Co., Ltd. and Qspex Technologies, Inc..

Qingdao's three-year grant acceleration

Qingdao Jiaonan Haier Washing Machine Co., Ltd. shows 4 grants in 2022–2024 against only 1 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.
