Where Daechang's grants concentrate

Daechang Seat Co. is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under B60N (Seats Specially Adapted FOR VEHICLES; Vehicle Passenger Accommodation NOT Otherwise Provided FOR). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2016. By volume, Daechang sits between Dacc Carbon and DAH KEN Industrial Co., Ltd..

Daechang's three-year grant acceleration

Daechang Seat Co. 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.
