Where 1934612's grants concentrate

1934612 Ontario Inc. is a focused PatentsView assignee: 7 CPC subclasses with 91.7% of grants classified under B01D (Separation). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2019. By volume, 1934612 sits between eResearchTechnology, Inc. and 3D Bridge Solutions Inc..

1934612's three-year grant acceleration

1934612 Ontario Inc. shows 5 grants in 2022–2024 against only 4 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.
