Where Nippon's grants concentrate

Nippon Thermostat Co., Ltd. is a focused PatentsView assignee: 22 CPC subclasses with 75.7% of grants classified under F01P (Cooling OF Machines OR Engines IN GENERAL; Cooling OF Internal-combustion Engines). Peak complete grant year is 2024 (10 grants) versus a trough of 1 in 2022. By volume, Nippon sits between Nakanishi Inc. and Novavax, Inc..

Nippon's three-year grant acceleration

Nippon Thermostat Co., Ltd. shows 12 grants in 2022–2024 against only 9 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.
