What this shows Cardio's Innovation Score is 39.0/100 (top 39% 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 Cardio?

Each dot is one of Cardio’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). Cardio’s own 19.4 claims/patent is ABOVE the 15.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Cardio's grants concentrate

Cardio Flow, Inc. is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2019 (11 grants) versus a trough of 1 in 2018. By volume, Cardio sits between Black Hills IP Holdings, LLC and Computational Systems, Inc..

Cardio's three-year grant acceleration

Cardio Flow, Inc. shows 20 grants in 2022–2024 against only 16 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.
