Does more volume mean deeper claims for Cantex?
Each dot is one of Cantex’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). Cantex’s own 27.1 claims/patent is ABOVE the 11.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Cantex's grants concentrate
Cantex International, Inc. is a focused PatentsView assignee: 6 CPC subclasses with 85.7% of grants classified under E21B (Earth OR Rock DRILLING; Obtaining OIL, GAS, Water, Soluble OR Meltable Materials OR A Slurry OF Minerals From Wells). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2019. By volume, Cantex sits between Can Do Logistics LLC and CarMax Business Services, LLC.
Cantex's three-year grant acceleration
Cantex International, Inc. shows 2 grants in 2022–2024 against only 5 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.
