Does more volume mean deeper claims for Dongguan?

Each dot is one of Dongguan’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). Dongguan’s own 1.0 claims/patent is at or below the 10.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dongguan's grants concentrate

Dongguan Huifeng Tech.Co., Ltd. is a focused PatentsView assignee: 0 CPC subclasses . Peak complete grant year is 2024 (4 grants) versus a trough of 3 in 2022. By volume, Dongguan sits between Dometic Marine Canada Inc. and Dr. Dabber Inc..

Dongguan's three-year grant acceleration

Dongguan Huifeng Tech.Co., Ltd. shows 7 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.
