Where Tohnichi's grants concentrate

Tohnichi Mfg.co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under B25B (TOOLS OR BENCH DEVICES NOT OTHERWISE PROVIDED FOR, FOR FASTENING, CONNECTING, DISENGAGING OR HOLDING). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2017. By volume, Tohnichi sits between THE Vitec Group Plc and Traffic Technology Services, Inc..

Tohnichi's three-year grant acceleration

Tohnichi Mfg.co., Ltd. shows 4 grants in 2022–2024 against only 3 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.
