Where Hokusan's grants concentrate

Hokusan Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2017. By volume, Hokusan sits between Hitachi Metals Techno, Ltd. and Honda Foundry Co., Ltd..

Hokusan's three-year grant acceleration

Hokusan Co., Ltd. shows 1 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.
