Legal analysis: not similar, but registered trademarks are risky. Suspected of selling counterfeit food, law enforcement officers can detain the "six pure walnuts" sold in the store. In this case, there is a serious phenomenon of hitchhiking and standing beside famous brands, which constitutes unfair competition, and an application is made to the Trademark Office to cancel the registered trademark. As can be seen from the website of the Trademark Office, these disputed trademarks are indeed in a revoked/invalid state. Hebei Yangyuan Zhihui Beverage Co., Ltd. must have started to deal with this matter. In addition, if the trademark angle fails, the six walnut companies can also start from protecting the unique packaging and decoration rights of well-known commodities, sue them for unfair competition and safeguard their legitimate rights and interests.

Legal basis: Article 3 of the Trademark Law of People's Republic of China (PRC) is a registered trademark, including commodity trademark, service trademark, collective trademark and certification trademark; Trademark registrants enjoy the exclusive right to use trademarks and are protected by law. The term "collective trademark" as mentioned in this Law refers to a sign registered in the name of a group, association or other organization for members of the organization to use in business activities, so as to show the membership of users in the organization. The term "certification trademark" as mentioned in this Law refers to a mark controlled by an organization with the ability to supervise goods or services and used by units or individuals outside the organization to prove the origin, raw materials, manufacturing methods, quality or other specific qualities of the goods or services. Special matters concerning the registration and management of collective trademarks and certification trademarks shall be stipulated by the administrative department for industry and commerce of the State Council.
