When applying for a patent for invention, the scope of protection of exclusive rights should be as large as possible, and then the remaining technical features that can bring technical effects should be put into the subordinate rights, and the technical effects brought by the corresponding technical features should be described in the specification.
In this way, in the substantive examination stage of an application for a patent for invention, the scope of protection is adjusted according to the results retrieved by the examiner.
I don't know what you mean by "impact review".
Personally, I think that the exclusive right in the application documents for a patent for invention must be as wide as possible, so as to obtain the patent right with the largest protection scope.
