What this shows Cardiofocus's Innovation Score is 37.2/100 (top 44% 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 Cardiofocus?

Each dot is one of Cardiofocus’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). Cardiofocus’s own 11.6 claims/patent is at or below the 17.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Cardiofocus's grants concentrate

CardioFocus, Inc. is a focused PatentsView assignee: 5 CPC subclasses with 73.7% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2022 (6 grants) versus a trough of 1 in 2015. By volume, Cardiofocus sits between Curonix LLC and Celularity Inc..

Cardiofocus's three-year grant acceleration

CardioFocus, Inc. shows 9 grants in 2022–2024 against only 5 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.
