It's mixed. These proceedings (along with other reforms, like limiting venue) have been very bad for litigation billing, as disputes are fewer and disposed of faster. But I think the consensus is that we're better off taking this hit than losing even more support from the public for patents and facing something more severe.
Rather, companies are happy they can use their patent lawyers to gum up the system and prevent judgments.
The IP lawyers who prepare post-grant patent petitions are happy with this ruling. Wouldn't you rather represent Google at the PTAB than represent the troll in court?
