What this shows Northern's Innovation Score is 54.1/100 (top 8% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Northern?

Each dot is one of Northern’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Northern’s own 18.7 claims/patent is ABOVE the 16.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

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.
