What this shows Sonnax's Innovation Score is 42.1/100 (top 31% 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 Sonnax?

Each dot is one of Sonnax’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). Sonnax’s own 15.5 claims/patent is at or below the 16.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sonnax's grants concentrate

Sonnax Transmission Company is a focused PatentsView assignee: 8 CPC subclasses with 69.2% of grants classified under F16D (Couplings FOR Transmitting ROTATION; CLUTCHES; Brakes). Peak complete grant year is 2024 (6 grants) versus a trough of 1 in 2020. By volume, Sonnax sits between Shanxi University and Synthes GmbH.

Sonnax's three-year grant acceleration

Sonnax Transmission Company shows 12 grants in 2022–2024 against only 7 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.
