What this shows Zhengzhou's Innovation Score is 43.4/100 (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.

Does more volume mean deeper claims for Zhengzhou?

Each dot is one of Zhengzhou’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). Zhengzhou’s own 6.9 claims/patent is at or below the 15.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Zhengzhou's grants concentrate

Zhengzhou University OF Light Industry is a focused PatentsView assignee: 11 CPC subclasses with 37.5% of grants classified under G06T (Image Data Processing OR Generation, IN General). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2022. By volume, Zhengzhou sits between Zhejiang Liankong Technologies Co., Ltd. and Zipwhip, LLC.

Zhengzhou's three-year grant acceleration

Zhengzhou University OF Light Industry shows 7 grants in 2022–2024 against only 0 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.
