What this shows Southwest's Innovation Score is 51.2/100 (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 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 11.6 claims/patent is at or below the 13.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Southwest's grants concentrate

Southwest University of Science and Technology is a focused PatentsView assignee: 24 CPC subclasses with 46.2% of grants classified under C08G (Macromolecular Compounds Obtained Otherwise Than BY Reactions Only Involving Unsaturated Carbon-to-carbon Bonds). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2018. By volume, Southwest sits between Solatube International, Inc. and Sports Art Industrial Co., Ltd..

Southwest's three-year grant acceleration

Southwest University of Science and Technology shows 8 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.
