What this shows Sigma's Innovation Score is 48.0/100 (top 17% 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 Sigma?

Each dot is one of Sigma’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). Sigma’s own 11.8 claims/patent is at or below the 19.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sigma's grants concentrate

Sigma Powertain, Inc. is a focused PatentsView assignee: 11 CPC subclasses with 69.2% of grants classified under F16D (Couplings FOR Transmitting ROTATION; CLUTCHES; Brakes). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2021. By volume, Sigma sits between Shriro Australia Pty Limited and Sirius XM Connected Vehicle Services Inc..

Sigma's three-year grant acceleration

Sigma Powertain, Inc. shows 9 grants in 2022–2024 against only 3 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.
