What this shows Volterra's Innovation Score is 43.2/100 (top 29% 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 Volterra's grants concentrate

Volterra Semiconductor LLC is a focused PatentsView assignee: 19 CPC subclasses with 67.9% of grants classified under H02M (Apparatus FOR Conversion Between AC AND AC, Between AC AND DC, OR Between DC AND DC, AND FOR USE With Mains OR Similar Power Supply SYSTEMS; Conversion OF DC OR AC Input Power Into Surge Output POWER;). Peak complete grant year is 2015 (26 grants) versus a trough of 1 in 2024. By volume, Volterra sits between Surpass Industry Co., Ltd. and Warn Industries, Inc..

Volterra's three-year grant acceleration

Volterra Semiconductor LLC shows 1 grants in 2022–2024 against only 12 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.
