What this shows Ocean's Innovation Score is 58.6/100 (top 4% 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 8.8 claims/patent is at or below the 15.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Ocean's grant cadence moved

Between 2020–2024, Ocean University OF China received 36 grants versus 11 in 2015–2019 (+227% equal-window velocity, above median growth). Across complete PatentsView years, output peaked in 2024 at 13 grants and bottomed in 2015 at 2. Lead class B63B accounts for 20% of the portfolio across 61 subclasses. Volume neighbours: Micro Focus Software Inc. (#6,174) and Roche Diagnostics International AG (#6,182).

Ocean's three-year grant acceleration

Ocean University OF China shows 26 grants in 2022–2024 against only 12 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.
