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.

Does more volume mean deeper claims for Magnasphere?

Each dot is one of Magnasphere’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). Magnasphere’s own 24.4 claims/patent is ABOVE the 17.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

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.
