What this shows Surface's Innovation Score is 42.5/100 (top 30% 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 Surface?

Each dot is one of Surface’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). Surface’s own 13.9 claims/patent is at or below the 17.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Surface's grants concentrate

Surface Tech LLC is a focused PatentsView assignee: 15 CPC subclasses with 64.3% of grants classified under C04B (Lime, MAGNESIA; SLAG; CEMENTS; Compositions Thereof, e.g. Mortars, Concrete OR Like Building MATERIALS; Artificial Stone ; Ceramics ; REFRACTORIES; Treatment OF Natural Stone). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2015. By volume, Surface sits between Sunlighten, LLC and Syntheon, LLC.

Surface's three-year grant acceleration

Surface Tech LLC shows 5 grants in 2022–2024 against only 3 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.
