Where PUC's grants concentrate

PUC Perfect Union Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 18.2% of grants classified under A47J (KITCHEN EQUIPMENT; COFFEE MILLS; SPICE MILLS; APPARATUS FOR MAKING BEVERAGES). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2022. By volume, PUC sits between Progress Lighting, Llc and Pacbrake Company.

PUC's three-year grant acceleration

PUC Perfect Union Co., Ltd. shows 5 grants in 2022–2024 against only 5 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.
