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 9.3 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 Chuan Optoelectronics Limited is a focused PatentsView assignee: 0 CPC subclasses . Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2022. By volume, Dongguan sits between DNA Electronics, Inc. and Doosan Mobility Innovation Inc..
Dongguan's three-year grant acceleration
Dongguan Chuan Optoelectronics Limited shows 2 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.
