What this shows Ocean's Innovation Score is 36.2/100 (top 47% 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 Ocean?

Each dot is one of Ocean’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). Ocean’s own 17.0 claims/patent is ABOVE the 13.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Ocean's grants concentrate

Ocean Power Technologies, Inc. is a focused PatentsView assignee: 14 CPC subclasses with 80% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2017. By volume, Ocean sits between NuvOx Pharma LLC and ODL, Incorporated.

Ocean's three-year grant acceleration

Ocean Power Technologies, Inc. shows 2 grants in 2022–2024 against only 3 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.
