Does more volume mean deeper claims for Cashman?

Each dot is one of Cashman’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). Cashman’s own 18.7 claims/patent is at or below the 19.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Cashman's grants concentrate

Cashman Dredging AND Marine Contracting, Co., LLC is a focused PatentsView assignee: 12 CPC subclasses with 57.1% of grants classified under B63B (Ships OR Other Waterborne VESSELS; Equipment FOR Shipping). Peak complete grant year is 2021 (5 grants) versus a trough of 1 in 2020. By volume, Cashman sits between Cambricon (XI'AN) Semiconductor Co., Ltd. and Catlam, LLC.

Cashman's three-year grant acceleration

Cashman Dredging AND Marine Contracting, Co., LLC shows 4 grants in 2022–2024 against only 10 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.
