My utility model patent has received the first notice of examination opinions, which contradicts the previous application and is not novel. What should I do?

Let's first look at the contradictory documents mentioned in the review comments. Is the technical scheme and implementation effect the same as what you are applying for now? If the technical scheme and technical effect are exactly the same, and the application date of the comparison document is before your application date, then there is no way. You can only give up this. If there is a conflict between the technical solutions protected by the affiliation, the affiliation can be deleted.
