Where Westech's grants concentrate

WesTech Engineering, LLC is a focused PatentsView assignee: 9 CPC subclasses with 87.5% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2016. By volume, Westech sits between Webb Wheel Products, Inc. and Whitehead Investments, LLC.

Westech's three-year grant acceleration

WesTech Engineering, LLC shows 2 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.
