Where National's grants concentrate

National DONG HWA University is a focused PatentsView assignee: 12 CPC subclasses with 90.9% of grants classified under A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2015. By volume, National sits between Nanhua Intelligent Precision Machine (shenzhen) Co., Ltd. and Native Instruments Gmbh.

National's three-year grant acceleration

National DONG HWA University shows 3 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.
