Ask whether the patent belongs to repeated authorization.

As far as I know, even the same applicant has the problem of novelty. As long as the earlier application has been published, the earlier application can be used to evaluate the novelty of the later application. The patent law does not stipulate that the novelty of the later application cannot be evaluated by the earlier application of the same applicant, but there is a conflict principle between the earlier application and the later application in the patent law.

In addition, the landlord's problem can be divided into two situations. One is that the two applications are the same, so the authorization must be repeated, and the other is similar. I think you also know that if the verdict is almost the same, you will be invalidated, and then the review Committee will judge it. If you don't agree with the conclusion of the review committee, you should go through judicial procedures and let the judges of Beijing Intermediate People's Court and Beijing High Court draw a conclusion.

I think you should have more than one invalid reason, including at least the legal provisions of the principle of one sex and the principle of three sex. Hehe ... that's all I can say. It's cold, so it's important to put on more clothes.
