Where Hayashi's grants concentrate

Hayashi Kogyosyo Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under H02K (Dynamo-electric Machines). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2019. By volume, Hayashi sits between Harmotec Co., Ltd. and Hefei General Machinery Research Institute Co., Ltd..

Hayashi's three-year grant acceleration

Hayashi Kogyosyo Co., Ltd. shows 3 grants in 2022–2024 against only 4 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.
