What this shows SRX's Innovation Score is 33.8/100 (45th 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 SRX?

Each dot is one of SRX’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). SRX’s own 14.4 claims/patent is at or below the 16.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where SRX's grants concentrate

SRX Cardio, LLC is a focused PatentsView assignee: 7 CPC subclasses with 92.3% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2018. By volume, SRX sits between Southern Company Services, Inc. and Stamicarbon B.V. Acting Under THE Name OF MT Innovation Center.

SRX's three-year grant acceleration

SRX Cardio, LLC shows 6 grants in 2022–2024 against only 6 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.
