What this shows Shenzhen's Innovation Score is 20.4/100 (7th 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 4.3 claims/patent is at or below the 15.8 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 Longsys Electronics Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 26.7% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2020 (7 grants) versus a trough of 1 in 2018. By volume, Shenzhen sits between Sharper Shape Oy and Silver Bullet Therapeutics, Inc..
Shenzhen's three-year grant acceleration
Shenzhen Longsys Electronics Co., Ltd. shows 2 grants in 2022–2024 against only 12 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.
