What this shows Signpath's Innovation Score is 31.7/100 (39th 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 Signpath?

Each dot is one of Signpath’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). Signpath’s own 12.5 claims/patent is at or below the 14.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Signpath's grants concentrate

Signpath Pharma Inc. is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2019 (5 grants) versus a trough of 1 in 2016. By volume, Signpath sits between Shadecraft, LLC and Smart Vent Products LLC.

Signpath's three-year grant acceleration

Signpath Pharma Inc. shows 5 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.
