Where Northern's grants concentrate

Northern Technologies International Corporation is a focused PatentsView assignee: 18 CPC subclasses with 44.4% of grants classified under C23F (Non-mechanical Removal OF Metallic Material From Surface ; Inhibiting Corrosion OF Metallic Material OR Incrustation IN GENERAL; Multi-step Processes FOR Surface Treatment OF Metallic Material Involvi). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2015. By volume, Northern sits between Nokia Siemens Networks GmbH & Co. KG and NyproMold Inc..

Northern's three-year grant acceleration

Northern Technologies International Corporation shows 4 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.
