Does more volume mean deeper claims for Cannuflow?

Each dot is one of Cannuflow’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). Cannuflow’s own 8.3 claims/patent is at or below the 13.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Cannuflow's grants concentrate

Cannuflow, Inc. is a focused PatentsView assignee: 3 CPC subclasses with 94.6% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2015 (6 grants) versus a trough of 2 in 2024. By volume, Cannuflow sits between Clearstream Technologies Limited and Clariant Finance (BVI) Limited.

Cannuflow's three-year grant acceleration

Cannuflow, Inc. shows 6 grants in 2022–2024 against only 9 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.
