What this shows Toflo's Innovation Score is 27.5/100 (24th 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 Toflo?

Each dot is one of Toflo’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). Toflo’s own 6.5 claims/patent is at or below the 9.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Toflo's grants concentrate

Toflo Corporation is a focused PatentsView assignee: 7 CPC subclasses with 50% of grants classified under G01F (Measuring Volume, Volume Flow, Mass Flow OR Liquid LEVEL; Metering BY Volume). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2019. By volume, Toflo sits between Times Fiber Communications, Inc. and Tomologic AB.

Toflo's three-year grant acceleration

Toflo Corporation shows 3 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.
