What this shows Xuzhou's Innovation Score is 25.4/100 (17th percentile 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 Xuzhou?

Each dot is one of Xuzhou’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). Xuzhou’s own 7.1 claims/patent is at or below the 14.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Xuzhou's grants concentrate

Xuzhou Coal Mine Safety Equipment Manufacture Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 80% of grants classified under B66B (ELEVATORS; Escalators OR Moving Walkways). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2017. By volume, Xuzhou sits between Xiwing E-COMMERCE(ZHUHAI) Co., Ltd and Xenco Medical, LLC.

Xuzhou's three-year grant acceleration

Xuzhou Coal Mine Safety Equipment Manufacture Co., Ltd. shows 1 grants in 2022–2024 against only 6 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.
