Where Dali's grants concentrate

Dali Medical Devices Ltd is a focused PatentsView assignee: 2 CPC subclasses with 100% 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 2020 (2 grants) versus a trough of 1 in 2017. By volume, Dali sits between Dynex Semiconductor Limited and DataTorrent, Inc..

Dali's three-year grant acceleration

Dali Medical Devices Ltd shows 6 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.
