What this shows Legrand's Innovation Score is 44.4/100 (top 26% 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 Legrand?

Each dot is one of Legrand’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). Legrand’s own 16.2 claims/patent is ABOVE the 14.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Legrand's grants concentrate

Legrand France is a focused PatentsView assignee: 19 CPC subclasses with 52% of grants classified under H02G (Installation OF Electric Cables OR Lines, OR OF Combined Optical AND Electric Cables OR Lines). Peak complete grant year is 2017 (5 grants) versus a trough of 1 in 2024. By volume, Legrand sits between Kyocera Senco Industrial Tools, Inc. and Lighting Defense Group, LLC.

Legrand's three-year grant acceleration

Legrand France shows 6 grants in 2022–2024 against only 5 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.
