What this shows Spirox's Innovation Score is 43.1/100 (top 29% 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 Spirox?

Each dot is one of Spirox’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). Spirox’s own 24.3 claims/patent is ABOVE the 14.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Spirox's grants concentrate

Spirox, Inc. is a focused PatentsView assignee: 6 CPC subclasses with 85.7% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2023 (5 grants) versus a trough of 1 in 2016. By volume, Spirox sits between Sonifi Solutions, Inc. and Stone Aerospace, Inc..

Spirox's three-year grant acceleration

Spirox, Inc. shows 11 grants in 2022–2024 against only 8 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.
