What this shows Shenzhen's Innovation Score is 29.9/100 (32nd 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 6.4 claims/patent is ABOVE the 1.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Shenzhen's grants concentrate

Shenzhen Chifrog Technology Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 28.6% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2020. By volume, Shenzhen sits between Shenzhen Aisiting Technology Co., Ltd and Shenzhen Finicare Co., Ltd..

Shenzhen's three-year grant acceleration

Shenzhen Chifrog Technology Co., Ltd. shows 4 grants in 2022–2024 against only 3 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.
