The advertisement uses someone else’s product to mosaic the trademark and appearance, which is an infringement. According to the provisions of the Trademark Law, in advertising, mosaics cannot completely cover the characteristics of the trademark and appearance, which can easily cause confusion among consumers and constitute an infringement of product copyright and trademark rights. Trademarks and appearances are important components of products and have the function of identifying and distinguishing them. Other companies or individuals are not allowed to use others' trademarks and appearances without authorization.
