Where Samhongsa's grants concentrate

Samhongsa Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 30% of grants classified under F16F (SPRINGS; SHOCK-ABSORBERS; Means FOR Damping Vibration). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2016. By volume, Samhongsa sits between Synthesis Energy Systems, Inc. and Sanhua Aweco Appliance Systems GmbH.

Samhongsa's three-year grant acceleration

Samhongsa Co., Ltd. shows 3 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.
