Where Karma's grants concentrate

Karma Medical Products Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 57.1% of grants classified under A61G (Transport, Personal Conveyances, OR Accommodation Specially Adapted FOR Patients OR Disabled Persons ; Operating Tables OR CHAIRS; Chairs FOR DENTISTRY; Funeral Devices). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2016. By volume, Karma sits between Kangstem Biotech Co., Ltd. and Kbio Holdings Limited.

Karma's three-year grant acceleration

Karma Medical Products Co., Ltd. shows 1 grants in 2022–2024 against only 3 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.
