Does more volume mean deeper claims for Cube?

Each dot is one of Cube’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). Cube’s own 13.4 claims/patent is ABOVE the 8.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Cube's grants concentrate

Cube Investments Limited is a focused PatentsView assignee: 6 CPC subclasses with 80% of grants classified under A47L (Domestic Washing OR Cleaning ; Suction Cleaners IN General). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2017. By volume, Cube sits between CTC—Centro de Tecnologia Canavieira S.A. and Cumulus Networks Inc..

Cube's three-year grant acceleration

Cube Investments Limited shows 1 grants in 2022–2024 against only 1 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.
