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 14.2 claims/patent is at or below the 18.6 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 Kingagroot Chemical Compound Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 92.3% of grants classified under C07D (Heterocyclic Compounds). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2020. By volume, Qingdao sits between QMotion, Incorporated and Quidnet Energy Inc..
Qingdao's three-year grant acceleration
Qingdao Kingagroot Chemical Compound Co., Ltd. shows 4 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.
