Where Castle's grants concentrate

Castle Island IP Holding LLC is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under G07F (Coin-freed OR Like Apparatus). By volume, Castle sits between Carraro S.P.A. and Cava Healthcare Inc..

Castle's three-year grant acceleration

Castle Island IP Holding LLC shows 3 grants in 2022–2024 against only 0 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.
