"Edge ball" is the phenomenon of registered trademarks appearing similar to famous brands. For companies, registering a trademark next to a famous brand is nothing more than trying to use the influence of other people's trademarks in the market to attract consumers. However, since this kind of behavior can easily confuse and misunderstand the source of the goods or services, the State Trademark Office often rejects such trademarks when examining them. Even if the application is not rejected, big-name companies will pursue legal liability.
