What this shows Xiangtan's Innovation Score is 51.0/100 (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 Xiangtan?

Each dot is one of Xiangtan’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). Xiangtan’s own 9.0 claims/patent is at or below the 11.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Xiangtan's grants concentrate

Xiangtan University is a focused PatentsView assignee: 32 CPC subclasses with 21.7% of grants classified under G06N (Computing Arrangements Based ON Specific Computational Models). Peak complete grant year is 2024 (6 grants) versus a trough of 1 in 2018. By volume, Xiangtan sits between Westfalia-Automotive GMBH and Yupoong, Inc..

Xiangtan's three-year grant acceleration

Xiangtan University shows 11 grants in 2022–2024 against only 5 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.
