What this shows Shaanxi's Innovation Score is 36.9/100 (top 45% 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 Shaanxi?

Each dot is one of Shaanxi’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). Shaanxi’s own 7.2 claims/patent is at or below the 11.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Shaanxi's grants concentrate

Shaanxi Normal University is a focused PatentsView assignee: 33 CPC subclasses with 35.7% of grants classified under G03D (Apparatus FOR Processing Exposed Photographic Materials ; Accessories Therefor). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2016. By volume, Shaanxi sits between Seoul Laser Dieboard System Co., Ltd. and Shenzhen Cootway Technology Co., Ltd..

Shaanxi's three-year grant acceleration

Shaanxi Normal University shows 3 grants in 2022–2024 against only 7 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.
