Where Roto-frank's grants concentrate

Roto-frank OF America, Inc. is a focused PatentsView assignee: 2 CPC subclasses with 28.6% of grants classified under E05C (Bolts OR Fastening Devices FOR Wings, Specially FOR Doors OR Windows). By volume, Roto-frank sits between RMZ Development LLC and RPL Holdings Limited.

Roto-frank's three-year grant acceleration

Roto-frank OF America, Inc. shows 1 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.
