What this shows Sotax's Innovation Score is 26.1/100 (19th 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 Sotax?

Each dot is one of Sotax’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). Sotax’s own 12.0 claims/patent is at or below the 14.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sotax's grants concentrate

Sotax Corporation is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). By volume, Sotax sits between Sonoscape Medical Corp. and Southeastern Metals Manufacturing Co. Inc..

Sotax's three-year grant acceleration

Sotax Corporation shows 1 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.
