Engineering firm Dyson has alleged that rival Bosch used an insider to steal company secrets.
Dyson filed legal proceedings against Bosch in the High Court on Tuesday, a Bosch spokeswoman told SC Magazine on Wednesday.
Dyson alleges that an employee working at its Malmesbury research facility passed details about Dyson motors to Bosch over a period of two years, according to the Independent.
"We have spent over 15 years and £100 million developing high speed brushless motors, which power our vacuum cleaners and Airblade hand dryers," Dyson research and development director Mark Taylor said in a statement. "We are demanding the immediate return of our intellectual property."
Bosch said the Dyson employee had a pre-existing consultancy agreement with Bosch Lawn and Garden.
"Bosch has sought to establish the full details of what occurred, including attempting to establish from Dyson what, if any, confidential information supposedly passed between Bosch and Dyson," Bosch said in a statement.
The Dyson documents were filed as 'Dyson Technology Limited v. Robert Bosch Limited & Ors, High Court of Justice, Chancery Division, HC12E04131', Bloomberg said on Wednesday.
