Where Ostara's grants concentrate

Ostara Nutrient Recovery Technologies Inc. is a focused PatentsView assignee: 8 CPC subclasses with 75% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2015. By volume, Ostara sits between Orthodyne Electronics Corporation and Otto Aero Company.

Ostara's three-year grant acceleration

Ostara Nutrient Recovery Technologies Inc. shows 1 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.
