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 7.8 claims/patent is ABOVE the 4.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Dongguan's grants concentrate
Dongguan Weihong Smart Home Technology Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 60% of grants classified under A47C (CHAIRS; SOFAS; Beds). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2024. By volume, Dongguan sits between Dongguan Paifan Electronic Technology Co., Ltd. and Dongguk University Gyeongju Campus Industry-academy Cooperation Foundation.
Dongguan's three-year grant acceleration
Dongguan Weihong Smart Home Technology Co., Ltd. shows 1 grants in 2022–2024 against only 4 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.
