The bolded is at least a clear distinction of previous Federal Circuit case law, so I'm not sure how you can seriously argue that Nautilus's effect will be nil. It's already had an effect.
We're not saying it has no change on the substance of the law. We're saying that the change won't impact the amount of work available to patent practitioners. You can still argue the same cases -- you just argue them under a slightly different rule.
In order to say that the change will impact the amount of patent litigation work, you have to believe that there is a substantial number of cases that will not be brought under the new standard but that would have been brought under the old standard. Any claim that was at least arguable under the old standard is still arguable under the new standard. Maybe there's a tiny fraction of cases that are much weaker post-Nautilus. But the impact on volume of work seems like it will be nil or approaching nil.
