Stefan's three-year grant acceleration

Stefan Pfaff Werkzeug- UND Formenbau GMBH & Co KG shows 5 grants in 2022–2024 against only 1 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.
