Where Yuken's grants concentrate

Yuken Industry Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 54.5% of grants classified under C23C (COATING METALLIC MATERIAL; COATING MATERIAL WITH METALLIC MATERIAL; SURFACE TREATMENT OF METALLIC MATERIAL BY DIFFUSION INTO THE SURFACE, BY CHEMICAL CONVERSION OR SUBSTITUTION; COATING BY VACUUM EVAP). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2015. By volume, Yuken sits between Xtreme Manufacturing, Llc and Zansors Llc.

Yuken's three-year grant acceleration

Yuken Industry Co., Ltd. shows 4 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.
