What this shows Moteurs's Innovation Score is 43.5/100 (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 Moteurs?

Each dot is one of Moteurs’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). Moteurs’s own 14.1 claims/patent is at or below the 14.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Moteurs's grants concentrate

Moteurs Leroy-Somer is a focused PatentsView assignee: 25 CPC subclasses with 72.2% of grants classified under H02K (Dynamo-electric Machines). Peak complete grant year is 2018 (10 grants) versus a trough of 2 in 2023. By volume, Moteurs sits between Monosol, LLC and Outotec Oyj.

Moteurs's three-year grant acceleration

Moteurs Leroy-Somer shows 9 grants in 2022–2024 against only 17 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.
