Where Ntdrill's grants concentrate

NTDrill Holdings, LLC is a focused PatentsView assignee: 2 CPC subclasses with 100% 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 2022 (4 grants) versus a trough of 1 in 2021. By volume, Ntdrill sits between NR Electric Engineering Co., Ltd. and Numascale AS.

Ntdrill's three-year grant acceleration

NTDrill Holdings, LLC shows 5 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.
