Where Prototus's grants concentrate

Prototus, Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under H02K (Dynamo-electric Machines). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2016. By volume, Prototus sits between Promix Solutions AG and Pulmera, Inc..

Prototus's three-year grant acceleration

Prototus, Ltd. shows 2 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.
