Where Stoneage's grants concentrate

Stoneage, Inc. is a focused PatentsView assignee: 31 CPC subclasses with 52.1% of grants classified under B08B (Cleaning IN GENERAL; Prevention OF Fouling IN General). Peak complete grant year is 2018 (9 grants) versus a trough of 4 in 2015. By volume, Stoneage sits between Rheinisch-Westfälische Technische Hochschule (RWTH) Aachen and TD Ameritrade IP Company, Inc..

Stoneage's three-year grant acceleration

Stoneage, Inc. shows 15 grants in 2022–2024 against only 17 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.
