Where Cisdi's grants concentrate

Cisdi Engineering Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 44.4% of grants classified under F27D (Details OR Accessories OF Furnaces, Kilns, Ovens OR Retorts, IN SO FAR AS They ARE OF Kinds Occurring IN More Than ONE Kind OF Furnace). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2019. By volume, Cisdi sits between CHZ Technologies, LLC and CLEAN.IO, Inc..

Cisdi's three-year grant acceleration

Cisdi Engineering Co., Ltd. shows 4 grants in 2022–2024 against only 4 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.
