What this shows Leggett's Innovation Score is 46.1/100 (top 22% 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 Leggett?

Each dot is one of Leggett’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). Leggett’s own 19.4 claims/patent is ABOVE the 9.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Leggett's grants concentrate

Leggett & Platt Canada Co. is a focused PatentsView assignee: 17 CPC subclasses with 66.7% of grants classified under B60N (Seats Specially Adapted FOR VEHICLES; Vehicle Passenger Accommodation NOT Otherwise Provided FOR). Peak complete grant year is 2015 (9 grants) versus a trough of 1 in 2016. By volume, Leggett sits between Kodiak Networks Inc and Life Technologies Holdings PTE Ltd.

Leggett's three-year grant acceleration

Leggett & Platt Canada Co. shows 10 grants in 2022–2024 against only 9 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.
