Where DAH's grants concentrate

DAH KEN Industrial Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 66.7% of grants classified under B62K (CYCLES; Cycle FRAMES; Cycle Steering DEVICES; Rider-operated Terminal Controls Specially Adapted FOR CYCLES; Cycle Axle SUSPENSIONS; Cycle Side-cars, Forecars, OR THE Like). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2018. By volume, DAH sits between Daechang Seat Co. and Damae Medical.

DAH's three-year grant acceleration

DAH KEN Industrial Co., Ltd. shows 3 grants in 2022–2024 against only 0 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.
