What this shows Corflow's Innovation Score is 40.3/100 (top 36% 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 Corflow?

Each dot is one of Corflow’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). Corflow’s own 18.4 claims/patent is ABOVE the 16.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Corflow's grants concentrate

CorFlow Therapeutics AG is a focused PatentsView assignee: 5 CPC subclasses with 88.9% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2019. By volume, Corflow sits between Control Devices, LLC and Crea IP B.V..

Corflow's three-year grant acceleration

CorFlow Therapeutics AG shows 6 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.
