What this shows Flow's Innovation Score is 46.2/100 (top 21% 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 Flow?

Each dot is one of Flow’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). Flow’s own 15.9 claims/patent is ABOVE the 12.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Flow's grants concentrate

Flow Control LLC is a focused PatentsView assignee: 29 CPC subclasses with 37.8% of grants classified under F04B (Positive-displacement Machines FOR LIQUIDS; Pumps). Peak complete grant year is 2019 (9 grants) versus a trough of 1 in 2020. By volume, Flow sits between Episurf Ip-management AB and Fisher & Paykel Appliances Limited.

Flow's three-year grant acceleration

Flow Control LLC shows 9 grants in 2022–2024 against only 12 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.
