Does more volume mean deeper claims for KRL?

Each dot is one of KRL’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). KRL’s own 24.2 claims/patent is ABOVE the 7.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where KRL's grants concentrate

KRL Holding Company, Inc. is a focused PatentsView assignee: 3 CPC subclasses with 88.9% of grants classified under F41A (Functional Features OR Details Common TO Both Smallarms AND Ordnance, e.g. CANNONS; Mountings FOR Smallarms OR Ordnance). Peak complete grant year is 2015 (3 grants) versus a trough of 1 in 2018. By volume, KRL sits between Kosme S.R.L. Unipersonale and Kurashiki Kako Co., Ltd..

KRL's three-year grant acceleration

KRL Holding Company, Inc. shows 1 grants in 2022–2024 against only 3 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.
