What this shows Freevalve's Innovation Score is 37.4/100 (top 44% 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 Freevalve?

Each dot is one of Freevalve’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). Freevalve’s own 17.6 claims/patent is at or below the 18.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Freevalve's grants concentrate

Freevalve AB is a focused PatentsView assignee: 14 CPC subclasses with 90.5% of grants classified under F01L (Cyclically Operating Valves FOR Machines OR Engines). Peak complete grant year is 2018 (5 grants) versus a trough of 1 in 2017. By volume, Freevalve sits between Exegy Incorporated and Fortanix, Inc..

Freevalve's three-year grant acceleration

Freevalve AB shows 4 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.
