What this shows Leum's Innovation Score is 43.3/100 (top 28% 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 Leum?

Each dot is one of Leum’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). Leum’s own 12.4 claims/patent is at or below the 13.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Leum's grants concentrate

Leum Engineering, Inc. is a focused PatentsView assignee: 3 CPC subclasses with 93.8% of grants classified under B65G (Transport OR Storage Devices, e.g. Conveyors FOR Loading OR Tipping, Shop Conveyor Systems OR Pneumatic Tube Conveyors). Peak complete grant year is 2023 (5 grants) versus a trough of 1 in 2020. By volume, Leum sits between Luxnet Corporation and LiveQoS Inc..

Leum's three-year grant acceleration

Leum Engineering, Inc. shows 12 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.
