What this shows Sigmagen's Innovation Score is 50.4/100 (top 13% 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 Sigmagen?

Each dot is one of Sigmagen’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). Sigmagen’s own 16.5 claims/patent is ABOVE the 14.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Sigmagen's grants concentrate

Sigmagen, Inc. is a focused PatentsView assignee: 12 CPC subclasses with 100% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2020. By volume, Sigmagen sits between Shur-Co, LLC and Silver Creek Pharmaceuticals, Inc..

Sigmagen's three-year grant acceleration

Sigmagen, Inc. shows 6 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.
