Is the utility model patent certificate still useful?

This provision is made to avoid duplication of authorization. If you want to double report in the future and the new type and invention patent right do not affect each other, it is suggested to write with snacks. A more convenient way is that the protection scope of the independent claims of the two patents is inconsistent. For example, a certain feature is only written in the new exclusive right, so that it is not necessary to declare the same invention-creation in the request when submitting.
