Where West's grants concentrate

West Affum Holdings DAC is a focused PatentsView assignee: 21 CPC subclasses with 96.9% of grants classified under A61N (ELECTROTHERAPY; MAGNETOTHERAPY; Radiation THERAPY; Ultrasound Therapy). Peak complete grant year is 2024 (38 grants) versus a trough of 4 in 2022. By volume, West sits between Sinfonia Technology Co., Ltd. and Bulgari S.P.A..

West's three-year grant acceleration

West Affum Holdings DAC shows 73 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.
