What this shows Sunstream's Innovation Score is 33.8/100 (45th 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 Sunstream?

Each dot is one of Sunstream’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). Sunstream’s own 19.4 claims/patent is ABOVE the 4.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Sunstream's grants concentrate

Sunstream Corporation is a focused PatentsView assignee: 5 CPC subclasses with 75% of grants classified under B63C (Launching, Hauling-out, OR Dry-docking OF VESSELS; Life-saving IN WATER; Equipment FOR Dwelling OR Working Under WATER; Means FOR Salvaging OR Searching FOR Underwater Objects). By volume, Sunstream sits between Sun Scientific, Inc. and Surround.IO.

Sunstream's three-year grant acceleration

Sunstream Corporation shows 1 grants in 2022–2024 against only 1 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.
