Does more volume mean deeper claims for Stowe?

Each dot is one of Stowe’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). Stowe’s own 16.9 claims/patent is ABOVE the 12.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Stowe's grants concentrate

Stowe Woodward Licensco LLC is a focused PatentsView assignee: 21 CPC subclasses with 84.6% of grants classified under D21F (Paper-making MACHINES; Methods OF Producing Paper Thereon). Peak complete grant year is 2015 (3 grants) versus a trough of 1 in 2016. By volume, Stowe sits between Starkeys LLC and SUN Medical Technology Research Corporation.

Stowe's three-year grant acceleration

Stowe Woodward Licensco LLC shows 2 grants in 2022–2024 against only 5 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.
