Where RJ's grants concentrate

RJ LEE Group, Inc. is a focused PatentsView assignee: 12 CPC subclasses with 50% of grants classified under B01D (Separation). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2016. By volume, RJ sits between Rimfrost Technologies AS and Roll-n-lock Corporation.

RJ's three-year grant acceleration

RJ LEE Group, 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.
