What this shows Shenzhen's Innovation Score is 26.0/100 (19th 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 Shenzhen?

Each dot is one of Shenzhen’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). Shenzhen’s own 2.6 claims/patent is at or below the 6.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Shenzhen's grants concentrate

Shenzhen Qiaohua Industries Limited is a focused PatentsView assignee: 7 CPC subclasses with 14.3% of grants classified under F21S (Non-portable Lighting DEVICES; Systems THEREOF; Vehicle Lighting Devices Specially Adapted FOR Vehicle Exteriors). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2020. By volume, Shenzhen sits between Shenzhen Everwin Precision Technology Co., Ltd. and Shonan Gosei-jushi Seisakusho K.K..

Shenzhen's three-year grant acceleration

Shenzhen Qiaohua Industries Limited shows 6 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.
