Where efolder's grants concentrate

eFolder Inc. is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2019. By volume, efolder sits between de Werth Group AG and etectRx, Inc..

efolder's three-year grant acceleration

eFolder Inc. 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.
