What this shows Xidian's Innovation Score is 57.9/100 (top 5% 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 Xidian's grants concentrate

Xidian University is a focused PatentsView assignee: 49 CPC subclasses with 19.7% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2024 (15 grants) versus a trough of 1 in 2015. By volume, Xidian sits between Toast, Inc. and Anthony, Inc..

Xidian's three-year grant acceleration

Xidian University shows 29 grants in 2022–2024 against only 16 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.
