Does more volume mean deeper claims for Columbus?

Each dot is one of Columbus’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). Columbus’s own 13.9 claims/patent is ABOVE the 12.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Columbus's grants concentrate

Columbus Industries, Inc. is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under B01D (Separation). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2015. By volume, Columbus sits between CloudGenix, Inc. and Consolidated Container Company LP.

Columbus's three-year grant acceleration

Columbus Industries, Inc. shows 2 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.
