Where Oishi's grants concentrate

Oishi Koseido Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2022. By volume, Oishi sits between Obsidian Therapeutics, Inc. and Omniscient Imaging, Inc..

Oishi's three-year grant acceleration

Oishi Koseido 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.
