What this shows Shenzhen's Innovation Score is 41.8/100 (top 32% 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.

Where Shenzhen's grants concentrate

Shenzhen Wanjia Lighting Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 42.9% of grants classified under F21Y (Indexing Scheme Associated With Subclasses F21k, F21l, F21s and F21v, Relating TO THE Form OR THE Kind OF THE Light Sources OR OF THE Colour OF THE Light Emitted). Peak complete grant year is 2024 (4 grants) versus a trough of 3 in 2018. By volume, Shenzhen sits between Shenzhen Sendis Semiconductor Co., Ltd and Shenzhen Zhonghongtian Technology Co., Ltd..

Shenzhen's three-year grant acceleration

Shenzhen Wanjia Lighting Co., Ltd. shows 4 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.
