Samsung Sued by Dyson Technology Over Vacuum Steering Patent

Samsung Electronics Co. (005930) was sued by Dyson Technology Ltd., the vacuum cleaner maker founded by U.K. inventor James Dyson, over claims his company’s steering technology was infringed.

The company sued over an invention called “a cleaning appliance with a steering mechanism,” Wiltshire, England-based Dyson said in an e-mailed statement. It filed the suits on Aug. 29 in London.

Dyson won a patent lawsuit against Samsung in 2009 over its cyclone vacuum cleaner technology. Suwon, South Korea-based Samsung has been embroiled in patent and copyright disputes against Apple Inc. over its smartphone and tablet computers on three continents.

“Samsung has many patent lawyers so I find it hard not to believe that this is a deliberate or utterly reckless infringement of our patent,” James Dyson said in the statement.

An e-mail sent to Samsung’s Korean press office out of normal working hours wasn’t immediately responded to.

The case is Dyson Technology Ltd. v Samsung Electronics Co., High Court of Justice, Chancery Division, case no. HC13A03838.
