Does more volume mean deeper claims for Guangdong?

Each dot is one of Guangdong’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). Guangdong’s own 3.3 claims/patent is at or below the 17.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Guangdong's grants concentrate

Guangdong Yingxin Technology Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 14.3% of grants classified under A61C (DENTISTRY; Apparatus OR Methods FOR Oral OR Dental Hygiene). Peak complete grant year is 2024 (13 grants) versus a trough of 3 in 2023. By volume, Guangdong sits between GrayMatter Robotics Inc. and Heartland AG Tech, Inc..

Guangdong's three-year grant acceleration

Guangdong Yingxin Technology Co., Ltd. shows 16 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.
