What this shows Taiyuan's Innovation Score is 43.5/100 (top 28% 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.

Where Taiyuan's grants concentrate

Taiyuan University of Science and Technology is a focused PatentsView assignee: 35 CPC subclasses with 30.8% of grants classified under B21D (Working OR Processing OF Sheet Metal OR Metal Tubes, Rods OR Profiles Without Essentially Removing MATERIAL; Punching Metal). Peak complete grant year is 2023 (6 grants) versus a trough of 1 in 2020. By volume, Taiyuan sits between Toptica Photonics, Inc. and The Government of the United States of America, represented by the Secretary of Homeland Security.

Taiyuan's three-year grant acceleration

Taiyuan University of Science and Technology shows 11 grants in 2022–2024 against only 10 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.
