TL;DR: "Most reexamination requests rely on a finding of obviousness, which is a far more subject[ive] standard than demonstrating a lack of novelty. A lack of novelty can be established by any one piece of prior art that discloses each of the key elements of claimed invention. In each of these cases Google has identified not one, but five separate pieces of prior art that each alone demonstrates a lack of novelty in…
If this is true, surely the judge will ask: if each of these claims can be invalidated by five separate pieces of prior art, why in the world were the patents granted in the first place?
I wonder how effective this will be in fending off the patent trolls (e.g. IV), probably not very ...unless... Washington could implement/regulate a streamlined method of invalidating patents with prior art, it could go a long way in protecting valid inventions, while creating a disincentive for firms filing frivolous lawsuits and patents.
I know the patent office is under-staffed/funded but, you've got to believe that far fewer patents would be filed if there was a more effective system for invalidation in place.
