What this shows Guandong's Innovation Score is 61.9/100 (top 3% 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 Guandong?

Each dot is one of Guandong’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). Guandong’s own 6.8 claims/patent is at or below the 14.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Guandong's grant cadence moved

Between 2020–2024, Guandong Ocean University received 25 grants versus 1 in 2015–2019 (+2400% equal-window velocity, top decile growth). Across complete PatentsView years, output peaked in 2024 at 14 grants and bottomed in 2019 at 1. Lead class Y02A accounts for 17.5% of the portfolio across 56 subclasses. Volume neighbours: Foster-Miller, Inc. (#8,032) and Guangdong Midea White Home Appliance Technology Innovation Center Co., Ltd. (#8,040).

Guandong's three-year grant acceleration

Guandong Ocean University shows 25 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.
