What this shows Southwest's Innovation Score is 65.1/100 (top 1% 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 Southwest?

Each dot is one of Southwest’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). Southwest’s own 8.6 claims/patent is at or below the 14.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Southwest's grant cadence moved

Between 2020–2024, Southwest Jiaotong University received 57 grants versus 3 in 2015–2019 (+1800% equal-window velocity, top decile growth). Across complete PatentsView years, output peaked in 2023 at 19 grants and bottomed in 2019 at 1. Lead class B60L accounts for 20% of the portfolio across 81 subclasses. Volume neighbours: Sargent Manufacturing Company (#4,686) and Technische Universiteit Eindhoven (#4,694).

Southwest's three-year grant acceleration

Southwest Jiaotong University shows 47 grants in 2022–2024 against only 11 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.
