Where Westendorf's grants concentrate

Westendorf Manufacturing Co., Inc. is a focused PatentsView assignee: 6 CPC subclasses with 85.7% of grants classified under E02F (DREDGING; Soil-shifting).

Westendorf's three-year grant acceleration

Westendorf Manufacturing Co., Inc. shows 1 grants in 2022–2024 against only 4 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.
