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 6.2 claims/patent is ABOVE the 1.0 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 Hesheng Machinery & Electric Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 80% of grants classified under F04B (Positive-displacement Machines FOR LIQUIDS; Pumps). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2020. By volume, Dongguan sits between Dongguan Boyi Furniture Co., Ltd. and Dongguan Meiluodi Electronics Co., Ltd.
Dongguan's three-year grant acceleration
Dongguan Hesheng Machinery & Electric Co., Ltd. shows 2 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.
