How are mutually exclusive species defined in patent claims?

Mutually exclusive species in patent claims are defined by their non-overlapping limitations. The MPEP 806.04(f) provides a clear definition:

“Claims to different species are mutually exclusive if one claim recites limitations disclosed for a first species but not a second, while a second claim recites limitations disclosed only for the second species and not the first.”

In simpler terms, each species claim must have unique features or characteristics that are not present in the other species claims. This ensures that the claims do not overlap in scope.
