Where Griswold's grants concentrate

Griswold Controls, LLC is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; Devices FOR Venting OR Aerating). Peak complete grant year is 2018 (4 grants) versus a trough of 1 in 2017. By volume, Griswold sits between Golden Bear LLC and Guangdong Bestek Medical Devices Co., Ltd..

Griswold's three-year grant acceleration

Griswold Controls, LLC shows 3 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.
