Does more volume mean deeper claims for Cccc?

Each dot is one of Cccc’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Cccc’s own 11.9 claims/patent is at or below the 11.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

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.
