1 case as defendant.
Dreame Technology Co., Ltd., which markets its products as Dreame or Dreametech, is a privately held Chinese consumer electronics company headquartered in Suzhou. While the company officially launched in 2017, its origins trace back to a 2015 university project founded by Yu Hao. Dreame is a part of the Xiaomi Ecological Chain and has received significant venture capital funding from firms including Shunwei Capital and IDG Capital. While revenue figures are not public, one 2026 report cited a global workforce of approximately 20,000 employees.
Dreame Technology is an operating company that designs and manufactures a wide range of home appliances and consumer electronics. Its core and best-known products are in the high-end floor care market, including robotic vacuum and mop combinations, cordless stick vacuums, and wet-dry vacuums. The company has expanded its product lines to include personal care items like high-speed hair dryers, robotic lawn mowers, and other smart home devices such as air purifiers and bladeless fans. Dreame has also signaled ambitions to enter additional categories, including smartphones and smart vehicles.
The company's patent litigation posture, based on tracked cases, is that of an operating company defending its products. Dreame Technology USA Inc. has been named as a defendant in one patent case and has not been tracked as a plaintiff. This pattern is typical of a technology manufacturer being targeted by patent assertion entities.
The single tracked lawsuit is Optimum Vector Dynamics LLC v. Dreame Technology USA Inc, filed in the Southern District of California in April 2026. The plaintiff, Optimum Vector Dynamics LLC, appears to be a non-practicing entity (NPE). Patent industry reporting firm RPX has linked Optimum Vector Dynamics to a network of other patent-monetization plaintiffs.
The accused products are various models of robotic vacuums and lawnmowers that feature smart mapping technology and mobile app integration.
