What this shows Sigma's Innovation Score is 37.7/100 (top 43% 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 17.2 claims/patent is ABOVE the 14.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Sigma's grants concentrate

Sigma Labs, Inc. is a focused PatentsView assignee: 12 CPC subclasses with 95.2% of grants classified under B33Y (Additive Manufacturing, i.e. Manufacturing OF Three-dimensional [3-D] Objects BY Additive Deposition, Additive Agglomeration OR Additive Layering, e.g. BY 3-D Printing, Stereolithography OR Selective ). Peak complete grant year is 2022 (8 grants) versus a trough of 1 in 2018. By volume, Sigma sits between Shenzhen Genorivision Technology Co. Ltd. and Skis Rossignol.

Sigma's three-year grant acceleration

Sigma Labs, Inc. shows 8 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.
