That view is incorrect. Most familiar with this space disagree as a number of recent rulings by the CAFC are realing in a lot of the abusive behavior by the ptab, and indeed their own problem judge Mayer.
As you know w Google VRNG Mayer used 101 sua sponte and misapplied it to kill those patents. During that phase of patent litigation it was happening to many, to the point all you had to say was 101 and the infringer won. That however, has since changed to a more balanced (but not completely) approach. Enfish is just one example, as it took away the nuclear defense of infringers.
Most familiar with this space and more importantly legal precedents know the suggestion made in the prior post while opinion is factually incorrect.
Suggestion that diligence on recent precendents is warranted given such commentary.
Good luck!
