Where Arvos's grants concentrate

Arvos Ljungstrom LLC is a focused PatentsView assignee: 20 CPC subclasses with 76.2% of grants classified under F28D (Heat-exchange Apparatus, NOT Provided FOR IN Another Subclass, IN Which THE Heat-exchange Media DO NOT Come Into Direct Contact). Peak complete grant year is 2019 (6 grants) versus a trough of 1 in 2017. By volume, Arvos sits between Ark Diagnostics, Inc. and Basf Agrochemical Products B.V..

Arvos's three-year grant acceleration

Arvos Ljungstrom LLC shows 5 grants in 2022–2024 against only 13 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.
