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 1.7 claims/patent is at or below the 11.9 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 Marshell Electric Vehicle Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 14.3% of grants classified under H01R (Electrically-conductive CONNECTIONS; Structural Associations OF A Plurality OF Mutually-insulated Electrical Connecting ELEMENTS; Coupling DEVICES; Current Collectors). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2016. By volume, Guangdong sits between Gsquared Medical LLC and Guangzhou Wondfo Biotech Co., Ltd..

Guangdong's three-year grant acceleration

Guangdong Marshell Electric Vehicle Co., Ltd. shows 3 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.
