What this shows Shenzhen's Innovation Score is 21.7/100 (9th 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 1.6 claims/patent is at or below the 9.6 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 Sangshen E-commerce Co., Ltd. is a focused PatentsView assignee: 1 CPC subclasses with 6.7% of grants classified under H10H (Inorganic Light-emitting Semiconductor Devices Having Potential Barriers). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2019. By volume, Shenzhen sits between Shenzhen Chuangwei-rgb Electronics Co., Ltd. and Sinowell (SHANGHAI) Co., Ltd..

Shenzhen's three-year grant acceleration

Shenzhen Sangshen E-commerce Co., Ltd. shows 8 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.
