However, some enterprises failed to register in time, which led to the registration of well-known trademarks and infringed on the interests of obligees. Taking well-known trademarks as enterprise names, it is easy for the general public to associate trademarks with enterprise names, especially well-known trademarks. Some enterprises will use other people's well-known trademarks as enterprise names in order to improve their popularity, which constitutes infringement. Taking well-known trademarks as domain names, with the continuous development of the network and the emergence of new things such as e-commerce and online shopping, domain names are unique and unrepeatable, which directly link people with well-known trademarks, so this kind of infringement is also increasing.
