What this shows Bunting's Innovation Score is 26.8/100 (21st 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 Bunting?

Each dot is one of Bunting’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). Bunting’s own 10.5 claims/patent is at or below the 18.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Bunting's grants concentrate

Bunting Magnetics Co. is a focused PatentsView assignee: 4 CPC subclasses with 50% of grants classified under B03C (Magnetic OR Electrostatic Separation OF Solid Materials From Solid Materials OR FLUIDS; Separation BY High-voltage Electric Fields). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2016. By volume, Bunting sits between Bryght Labs, LLC and Bystronic Lenhardt GmbH.

Bunting's three-year grant acceleration

Bunting Magnetics Co. shows 1 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.
