Because the trademark laws of some countries clearly stipulate that the use of a surname as a trademark must obtain the consent of the owner of the surname. If the person to whom the surname belongs has recently passed away, obtain the consent of his legal representative or agent.

For example, the English translations attached to some domestic trademarks happen to contain the surnames or surnames of foreigners, including the English "Forward" of the "Qianjin" trademark, the English "Forward" of the "Zhengshi" trademark The English "Diamond", the English "Swan" of the "Swan" trademark, and the "Violet" of the "Violet" trademark have the same pronunciation or similar meanings to the British surnames such as Swanson, Forwater, Diamond and Violet. Several trademarks have encountered many obstacles when registering abroad, and some cannot be registered at all.
