Does more volume mean deeper claims for Louisville?

Each dot is one of Louisville’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). Louisville’s own 7.8 claims/patent is at or below the 11.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Louisville's grants concentrate

Louisville Ladder Inc. is a focused PatentsView assignee: 2 CPC subclasses with 53.8% of grants classified under E06C (Ladders). Peak complete grant year is 2020 (6 grants) versus a trough of 1 in 2022. By volume, Louisville sits between Lionhead Helmet Intellectual Properties, LP and Lakeshore Learning Materials, LLC.

Louisville's three-year grant acceleration

Louisville Ladder Inc. shows 1 grants in 2022–2024 against only 10 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.
