Cardex Systems Inc. is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under G07F (Coin-freed OR Like Apparatus). By volume, Cardex sits between Captron Electronic GmbH and Carefusion Switzerland 317 SÀRL.
Cardex Systems Inc. shows 2 grants in 2022–2024 against only 1 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.
