Where National's grants concentrate

National University Corporation Okayama University is a focused PatentsView assignee: 46 CPC subclasses with 46.4% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2015 (16 grants) versus a trough of 3 in 2018. By volume, National sits between Litepoint Corporation and PAX Labs, Inc..

National's three-year grant acceleration

National University Corporation Okayama University shows 15 grants in 2022–2024 against only 19 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.
