What this shows Opacmare's Innovation Score is 23.6/100 (13th 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 Opacmare?

Each dot is one of Opacmare’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). Opacmare’s own 6.8 claims/patent is at or below the 18.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Opacmare's grants concentrate

Opacmare S.R.L. is a focused PatentsView assignee: 3 CPC subclasses with 83.3% of grants classified under B63B (Ships OR Other Waterborne VESSELS; Equipment FOR Shipping). Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2016. By volume, Opacmare sits between Onejoon GMBH and Oppo Medical Inc..

Opacmare's three-year grant acceleration

Opacmare S.R.L. 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.
