>Scott McKeown has identified what he believes are some instances of parties not involved in a case of patent litigation using the inter partes review (IPR) procedure to squeeze money out of patent owners who’ve won court cases but haven’t yet received a check. Since IPRs are conducted by the Patent Trial and Appeal Board (PTAB) you could call these operators “PTAB Trolls.”
If patent trolls are moving to this, it seems to be a great development for society, since it makes patent trolling itself by both NPEs and PEs less profitable or unprofitable.
The legal system still seem to be broken, because it should offer a large reward to the "PTAB troll" to be paid by the patent owner so that instead of settling they would go through and invalidate the patent, while still getting money from the patent owner, who would also lose the money from the (non-)infringer.
