What this shows Sigma's Innovation Score is 26.4/100 (20th 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 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 7.3 claims/patent is at or below the 18.0 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 Enterprises, LLC is a focused PatentsView assignee: 4 CPC subclasses with 32.1% of grants classified under A46B (Brushes). Peak complete grant year is 2017 (10 grants) versus a trough of 1 in 2019. By volume, Sigma sits between Shima Seiki MFG., Ltd. and Synack, Inc..

Sigma's three-year grant acceleration

Sigma Enterprises, LLC shows 1 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.
