What this shows Dowco's Innovation Score is 42.3/100 (top 31% 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 Dowco?

Each dot is one of Dowco’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). Dowco’s own 19.1 claims/patent is ABOVE the 17.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Dowco's grants concentrate

Dowco LLC is a focused PatentsView assignee: 20 CPC subclasses with 64.5% of grants classified under B63B (Ships OR Other Waterborne VESSELS; Equipment FOR Shipping). Peak complete grant year is 2017 (8 grants) versus a trough of 1 in 2015. By volume, Dowco sits between Chrysler Group LLC and Delphix Corp..

Dowco's three-year grant acceleration

Dowco LLC shows 5 grants in 2022–2024 against only 11 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.
