Where Cardiac's grants concentrate

Cardiac Assist Holdings, LLC is a focused PatentsView assignee: 8 CPC subclasses with 96.2% of grants classified under A61M (Devices FOR Introducing Media Into, OR Onto, THE Body ; Devices FOR Transducing Body Media OR FOR Taking Media From THE Body ; Devices FOR Producing OR Ending Sleep OR Stupor). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2016. By volume, Cardiac sits between China Telecom Corporation Limited and Centre Luxembourgeois de Recherches pour le Verre et la Ceramique S.A. (C.R.V.C.).

Cardiac's three-year grant acceleration

Cardiac Assist Holdings, LLC shows 8 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.
