Where Daiken's grants concentrate

Daiken Medical Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 87.5% 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 2024 (2 grants) versus a trough of 1 in 2015. By volume, Daiken sits between D&R Tech LLC and DATA:)COMM Electronics, Inc..

Daiken's three-year grant acceleration

Daiken Medical Co., Ltd. shows 3 grants in 2022–2024 against only 2 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.
