Legal subjectivity:

Legal, r is a registered trademark mark, and tm generally refers to a trademark mark under application. These marks can be placed on the product or not used. If there is no mark on the product trademark, it may be that the trademark is not registered, or it may be that the trademark is registered without a mark. Not required to use or label. The law is objective:

Article 63 of the "Regulations for the Implementation of the Trademark Law" stipulates that when using a registered trademark, a "registered trademark" or registered mark may be marked on goods, product packaging, instructions or other attachments.
