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 6.1 claims/patent is at or below the 8.3 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 Kentec Office Seating Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 60.9% of grants classified under A47C (CHAIRS; SOFAS; Beds). Peak complete grant year is 2017 (8 grants) versus a trough of 1 in 2020. By volume, Dongguan sits between Custom Dynamics, LLC and Dango Products, LLC.
Dongguan's three-year grant acceleration
Dongguan Kentec Office Seating Co., Ltd. shows 2 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.
