The examination opinions stipulated in Article 22, paragraph 3 of the Patent Law are not innovative. Can they be authorized?

It's possible. If the review opinion does not think that all the claims are not innovative, then it does not indicate that the claims that are not innovative can be authorized, or may be authorized to add new features that are not available in the existing technology from the specification. Finally, if the review opinion is unreasonable, it can be authorized after argumentation.
