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 12.1 claims/patent is ABOVE the 11.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Guangdong's grants concentrate

Guangdong Welling Motor Manufacturing Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 45% of grants classified under H02K (Dynamo-electric Machines). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2018. By volume, Guangdong sits between Global Store Supply Inc. and Genomic Health, Inc..

Guangdong's three-year grant acceleration

Guangdong Welling Motor Manufacturing Co., Ltd. shows 8 grants in 2022–2024 against only 6 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.
