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 2.8 claims/patent is at or below the 12.3 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 Hongyu Plastic Rubber Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 25% of grants classified under A47C (CHAIRS; SOFAS; Beds). Peak complete grant year is 2023 (4 grants) versus a trough of 1 in 2021. By volume, Dongguan sits between DNT Scientific Research, LLC and Dowooinsys Co., Ltd..

Dongguan's three-year grant acceleration

Dongguan Hongyu Plastic Rubber Co., Ltd. shows 7 grants in 2022–2024 against only 1 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.
