The products of the two companies are almost the same, but in terms of brand effect value, Huawei was certainly chosen (in addition, Huashan was also a former subsidiary of Huawei, and Huawei put the original low-end network products and related technicians into the production of Huawei 3com, the predecessor of Huashan, and Huawei firmly grasped the high-end product line and its technology and development team). The birth of Huashan Company originated from the patent war between Huawei and Cisco. In 2003, Cisco suddenly sued Huawei in the United States. In response to the lawsuit, Huawei and 3com established Huawei 3com in Hangzhou, in which Huawei owns 565,438+0% of the shares and 3com owns 49% of the shares. Huawei put low-end switches and other products into Huawei 3com for development, and the entire development and sales team also moved to Huawei 3com, located in Shenzhen Bantian Huawei Base. In 2005, 3com bought the equity of %2 from Huawei. In 2006, 3com bought all the shares for more than 800 million dollars, and Huawei 3com officially changed its name to h3c. H3c Huashan is currently a subsidiary of HP.
