What this shows Lamkin's Innovation Score is 26.8/100 (21st percentile 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 Lamkin?

Each dot is one of Lamkin’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). Lamkin’s own 8.4 claims/patent is at or below the 14.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Lamkin's grants concentrate

Lamkin Corporation is a focused PatentsView assignee: 4 CPC subclasses with 55.6% of grants classified under A63B (Apparatus FOR Physical Training, Gymnastics, Swimming, Climbing, OR FENCING; Ball GAMES; Training Equipment). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2018. By volume, Lamkin sits between L'Orange GMBH and Laporte Holding.

Lamkin's three-year grant acceleration

Lamkin Corporation shows 1 grants in 2022–2024 against only 0 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.
