yes. According to Article 57 of the Trademark Law, even if Taobao stores don't sell branded products, they may infringe on intellectual property rights. If stores can use brand names or trademarks in publicity materials and website information without authorization, and in addition, stores use brand-specific words or pictures in product descriptions without relevant brand rights, these behaviors infringe on the intellectual property rights of brand owners and constitute infringement. Therefore, whether the goods sold by Taobao stores are branded products or not, they should try their best.
