Where Cccc's grants concentrate

Cccc First Harbor Engineering Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 66.7% of grants classified under E02D (FOUNDATIONS; EXCAVATIONS; Embankments ; Underground OR Underwater Structures). Peak complete grant year is 2023 (3 grants) versus a trough of 2 in 2020. By volume, Cccc sits between Carfoldio Ltd. and Celon Pharma S.A..

Cccc's three-year grant acceleration

Cccc First Harbor Engineering Co., Ltd. shows 5 grants in 2022–2024 against only 2 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.
