What this shows Smartflow's Innovation Score is 34.8/100 (49th 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 Smartflow?

Each dot is one of Smartflow’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). Smartflow’s own 9.5 claims/patent is at or below the 12.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Smartflow's grants concentrate

Smartflow Technologies, Inc. is a focused PatentsView assignee: 15 CPC subclasses with 100% of grants classified under B01D (Separation). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2019. By volume, Smartflow sits between Silicon Display Technology and Spectrum Medical Ltd..

Smartflow's three-year grant acceleration

Smartflow Technologies, Inc. shows 5 grants in 2022–2024 against only 7 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.
