Where Kawasumi's grants concentrate

Kawasumi Laboratories, Inc. is a focused PatentsView assignee: 4 CPC subclasses with 55.6% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2016. By volume, Kawasumi sits between KAI Pharmaceuticals, Inc. and Keene Building Products Co., Inc..

Kawasumi's three-year grant acceleration

Kawasumi Laboratories, Inc. shows 5 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.
