What this shows Ferrarispower's Innovation Score is 34.2/100 (47th 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 Ferrarispower?

Each dot is one of Ferrarispower’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). Ferrarispower’s own 10.3 claims/patent is at or below the 14.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Ferrarispower's grants concentrate

Ferrarispower Co., Ltd. is a focused PatentsView assignee: 16 CPC subclasses with 71.4% of grants classified under H02J (Circuit Arrangements OR Systems FOR Supplying OR Distributing Electric POWER; Systems FOR Storing Electric Energy). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2022. By volume, Ferrarispower sits between Fedrigoni S.P.A. and Fhoosh, Inc..

Ferrarispower's three-year grant acceleration

Ferrarispower Co., Ltd. shows 2 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.
