What this shows Subseasail's Innovation Score is 37.9/100 (top 42% 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 Subseasail?

Each dot is one of Subseasail’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). Subseasail’s own 18.4 claims/patent is ABOVE the 15.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Subseasail's grants concentrate

SubSeaSail, Inc. is a focused PatentsView assignee: 12 CPC subclasses with 88.9% of grants classified under B63B (Ships OR Other Waterborne VESSELS; Equipment FOR Shipping). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2018. By volume, Subseasail sits between Stormtrap, LLC and Sun Hill Industries, Inc..

Subseasail's three-year grant acceleration

SubSeaSail, Inc. shows 4 grants in 2022–2024 against only 4 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.
