Does more volume mean deeper claims for Sigmastar?

Each dot is one of Sigmastar’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). Sigmastar’s own 12.7 claims/patent is at or below the 15.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sigmastar's grants concentrate

Sigmastar Technology Ltd. is a focused PatentsView assignee: 22 CPC subclasses with 40% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2024 (16 grants) versus a trough of 1 in 2021. By volume, Sigmastar sits between Roche Glycart AG and Thales Canada Inc..

Sigmastar's three-year grant acceleration

Sigmastar Technology Ltd. shows 30 grants in 2022–2024 against only 1 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.
