Does more volume mean deeper claims for Profusa?

Each dot is one of Profusa’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). Profusa’s own 21.0 claims/patent is ABOVE the 14.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Profusa's grants concentrate

Profusa, Inc is a focused PatentsView assignee: 11 CPC subclasses with 96.2% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2017. By volume, Profusa sits between Perfect Company and Qingdao University of Science and Technology.

Profusa's three-year grant acceleration

Profusa, Inc shows 7 grants in 2022–2024 against only 10 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.
