Where Caldwell's grants concentrate

Caldwell Manufacturing Company North America, LLC is a focused PatentsView assignee: 8 CPC subclasses with 92.9% of grants classified under E05D (Hinges OR Suspension Devices FOR Doors, Windows OR Wings). Peak complete grant year is 2015 (7 grants) versus a trough of 1 in 2017. By volume, Caldwell sits between Crucialtec Co. Ltd and Clariant Produkte (Deutschland) GmbH.

Caldwell's three-year grant acceleration

Caldwell Manufacturing Company North America, LLC shows 3 grants in 2022–2024 against only 7 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.
