What this shows Sellmark's Innovation Score is 31.1/100 (36th 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 Sellmark?

Each dot is one of Sellmark’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). Sellmark’s own 7.8 claims/patent is at or below the 17.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sellmark's grants concentrate

Sellmark Corporation is a focused PatentsView assignee: 5 CPC subclasses with 45% of grants classified under F41G (Weapon SIGHTS; Aiming). Peak complete grant year is 2023 (4 grants) versus a trough of 1 in 2015. By volume, Sellmark sits between Swiftlink Technologies Inc. and Shindig, Inc..

Sellmark's three-year grant acceleration

Sellmark Corporation shows 6 grants in 2022–2024 against only 5 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.
