according to the inquiry and non-network, Bosch and Siemens are only cooperative. In 1967, Bosch and Siemens each invested 5% to establish Bosi Household Appliances Group, which produced household appliances and branded Bosch or Siemens trademarks. Bosi Company's operation has always been dominated by Bosch Company, and the household appliances sold in the market are under the brand of Siemens, but it has little to do with Siemens, and Siemens has not produced household appliances. In 214, Siemens transferred 5% of the shares of Bosi Company to Bosch.
