I don't think patents are inherently evil; and I also believe that "obvious" patents will get less common with time (relatively speaking we're still in the early days of patent law for many areas).
That being said, I think the big issue we're seeing these days is that some patent categories simply last too long. Technology moves a mile a minute, a patent system with a duration of 20 years is absurd, something that was innovative in 1997 doesn't continue to provide the same level of value in 2007 let alone 2017.
At absolute MOST the patent duration for technology patents should be halved. Ten years is still too long but at least there's a chance the entire industry doesn't overtake the patent too much, five years would be better but realistically patents are fairly expensive to file so the whole system might collapse.
