What this shows Shanghai's Innovation Score is 51.3/100 (top 12% 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 Shanghai?

Each dot is one of Shanghai’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). Shanghai’s own 7.7 claims/patent is at or below the 10.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Shanghai's grants concentrate

Shanghai Maritime University is a focused PatentsView assignee: 27 CPC subclasses with 40% of grants classified under G06N (Computing Arrangements Based ON Specific Computational Models). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2020. By volume, Shanghai sits between Shandong Danhong Pharmaceutical Co., Ltd. and Shenzhen Bell Creative Science AND Education Co., Ltd..

Shanghai's three-year grant acceleration

Shanghai Maritime University shows 6 grants in 2022–2024 against only 2 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.
