What this shows Magnasphere's Innovation Score is 33.5/100 (44th percentile 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.

Where Magnasphere's grants concentrate

Magnasphere Corporation is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under H01H (Electric SWITCHES; RELAYS; SELECTORS; Emergency Protective Devices). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2018. By volume, Magnasphere sits between Macton Corporation and Manchester Copper Products, LLC.

Magnasphere's three-year grant acceleration

Magnasphere Corporation shows 1 grants in 2022–2024 against only 2 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.
