Where Okada's grants concentrate

Okada Medical Supply Co., Ltd. is a focused PatentsView assignee: 1 CPC subclasses with 100% of grants classified under A61C (DENTISTRY; Apparatus OR Methods FOR Oral OR Dental Hygiene). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2015. By volume, Okada sits between Ohsung Electronics Co., Ltd. and Olea Medical.

Okada's three-year grant acceleration

Okada Medical Supply Co., Ltd. shows 4 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.
