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.
