Does more volume mean deeper claims for Kadant?

Each dot is one of Kadant’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). Kadant’s own 16.6 claims/patent is ABOVE the 10.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kadant's grants concentrate

Kadant Black Clawson LLC is a focused PatentsView assignee: 7 CPC subclasses with 62.5% of grants classified under B01D (Separation). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2016. By volume, Kadant sits between Kyocera Crystal Device Corporation and Karem Aircraft, Inc..

Kadant's three-year grant acceleration

Kadant Black Clawson LLC shows 3 grants in 2022–2024 against only 1 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.
