What this shows Subsurface's Innovation Score is 39.7/100 (top 38% 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 Subsurface?

Each dot is one of Subsurface’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). Subsurface’s own 20.4 claims/patent is ABOVE the 11.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Subsurface's grants concentrate

Subsurface, Inc. is a focused PatentsView assignee: 4 CPC subclasses with 47.4% of grants classified under E02D (FOUNDATIONS; EXCAVATIONS; Embankments ; Underground OR Underwater Structures). Peak complete grant year is 2022 (5 grants) versus a trough of 1 in 2017. By volume, Subsurface sits between Stern Pinball, Inc. and SynDevRx, Inc..

Subsurface's three-year grant acceleration

Subsurface, Inc. shows 9 grants in 2022–2024 against only 6 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.
