Where Cosmo's grants concentrate

Cosmo Koki Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under F16L (PIPES; Joints OR Fittings FOR PIPES; Supports FOR Pipes, Cables OR Protective TUBING; Means FOR Thermal Insulation IN General). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2017. By volume, Cosmo sits between Conway Electric, LLC and CP Studios LLC.

Cosmo's three-year grant acceleration

Cosmo Koki Co., Ltd. shows 5 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.
