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 1.0 claims/patent is at or below the 5.6 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 Earfun Technology Co., Ltd. is a focused PatentsView assignee: 0 CPC subclasses . Peak complete grant year is 2023 (6 grants) versus a trough of 1 in 2022. By volume, Shenzhen sits between Sensient Colors LLC and Shenzhen Yile Dynamic Technology Co., Ltd.
Shenzhen's three-year grant acceleration
Shenzhen Earfun Technology Co., Ltd. shows 12 grants in 2022–2024 against only 5 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.
