What this shows Shenzhen's Innovation Score is 33.8/100 (46th 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 1.2 claims/patent is at or below the 10.9 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 Crastal Technology Co., Ltd. is a focused PatentsView assignee: 1 CPC subclasses with 6.7% of grants classified under A47J (Kitchen EQUIPMENT; Coffee MILLS; Spice MILLS; Apparatus FOR Making Beverages). Peak complete grant year is 2024 (11 grants) versus a trough of 1 in 2019. By volume, Shenzhen sits between Shanghai Institutes for Biological Sciences Chinese Academy of Sciences and Sigmoid Pharma Limited.

Shenzhen's three-year grant acceleration

Shenzhen Crastal Technology Co., Ltd. shows 11 grants in 2022–2024 against only 2 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.
