Patents need to be discriminated based on some threshold of originality or something similar. My country even has a term for it "verkshöjd" that is applied in this context. That way you don't get trolls trying to sue Amazon for "Way to sell merchandise using a >>computer network>>."

Of course there's no easy way to distinguish _all_ patent (applications) this way but that one would not be accepted.

The issues you raise are certainly valid and reasonable but notwithstanding not the point of contention here. The trolling part is the one that comes from what is perceived as illegitimate claims/ patents.
