Shanghai dpdupi lighting electrical co. Ltd is a focused PatentsView assignee: 0 CPC subclasses . By volume, Shanghai sits between Shanghai Reach Medical Instrument Co., Ltd. and Shenyang Kangende Medical Science and Technology Co., Ltd..
Shanghai dpdupi lighting electrical co. Ltd shows 4 grants in 2022–2024 against only 0 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.
