Where Ouro's grants concentrate

Ouro Negro Tecnologias Em Equipamentos Industriais S/A is a focused PatentsView assignee: 3 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 (2 grants) versus a trough of 1 in 2019. By volume, Ouro sits between Ortoma AB and Oxcion Limited.

Ouro's three-year grant acceleration

Ouro Negro Tecnologias Em Equipamentos Industriais S/A shows 3 grants in 2022–2024 against only 3 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.
