What this shows Northern's Innovation Score is 58.4/100 (top 4% 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 20.0 claims/patent is ABOVE the 12.8 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 Digital Inc. is a focused PatentsView assignee: 18 CPC subclasses with 57.7% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2022 (7 grants) versus a trough of 1 in 2021. By volume, Northern sits between Napra Co., Ltd. and Otonomy, Inc..

Northern's three-year grant acceleration

Northern Digital Inc. shows 14 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.
