What this shows Signalfox's Innovation Score is 28.2/100 (26th 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 Signalfox?

Each dot is one of Signalfox’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). Signalfox’s own 19.3 claims/patent is ABOVE the 4.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Signalfox's grants concentrate

SignalFox, Inc. is a focused PatentsView assignee: 3 CPC subclasses with 73.3% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2019 (6 grants) versus a trough of 1 in 2020. By volume, Signalfox sits between Shenzhen Glocusent Technology co. ltd and Singer Sourcing Limited LLC.

Signalfox's three-year grant acceleration

SignalFox, Inc. shows 1 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.
