What this shows Langeman's Innovation Score is 37.9/100 (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 Langeman?

Each dot is one of Langeman’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). Langeman’s own 16.2 claims/patent is ABOVE the 14.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Langeman's grants concentrate

Langeman Manufacturing Limited is a focused PatentsView assignee: 6 CPC subclasses with 40% of grants classified under B05B (Spraying APPARATUS; Atomising APPARATUS; Nozzles). By volume, Langeman sits between Laizhou Hongyuan Bench Vice Manufacture Co., Ltd. and Largo Clean Energy Corp..

Langeman's three-year grant acceleration

Langeman Manufacturing Limited shows 2 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.
