Does more volume mean deeper claims for Keen?

Each dot is one of Keen’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). Keen’s own 11.8 claims/patent is at or below the 17.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Keen's grants concentrate

Keen, Inc. is a focused PatentsView assignee: 5 CPC subclasses with 66.7% of grants classified under A43B (Characteristic Features OF FOOTWEAR; Parts OF Footwear). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2023. By volume, Keen sits between Kazuar Advanced Technologies Ltd. and Kessler Corporation.

Keen's three-year grant acceleration

Keen, Inc. shows 2 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.
