Does more volume mean deeper claims for Walker?

Each dot is one of Walker’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). Walker’s own 20.5 claims/patent is ABOVE the 4.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Walker's grants concentrate

Walker Digital Table Systems, LLC is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under G07F (Coin-freed OR Like Apparatus). Peak complete grant year is 2024 (6 grants) versus a trough of 1 in 2015. By volume, Walker sits between West Coast Imports, Inc. and Xiamen Longstar Lighting Co., Ltd..

Walker's three-year grant acceleration

Walker Digital Table Systems, LLC shows 14 grants in 2022–2024 against only 12 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.
