What this shows QKM's Innovation Score is 46.5/100 (top 21% 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 QKM?

Each dot is one of QKM’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). QKM’s own 15.2 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 QKM's grants concentrate

QKM Technology (DONG GUAN) Co., Ltd is a focused PatentsView assignee: 10 CPC subclasses with 40% of grants classified under G05B (Control OR Regulating Systems IN GENERAL; Functional Elements OF Such SYSTEMS; Monitoring OR Testing Arrangements FOR Such Systems OR Elements). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2021. By volume, QKM sits between Qingdao Sanyi Plastic Machinery Co., Ltd. (CN) and Qsigma, Inc..

QKM's three-year grant acceleration

QKM Technology (DONG GUAN) 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.
