EB case appears to be the Arris loss on appeal due to time bound on PTAB non-institute IPR. Apparently, Arris wants "en banc" court (all judges in Fed Appeals Court) to rehear case. Delaying tactic which will produce same result - a loss. Then they still have the Supreme Court. This would be just a "Hail Mary" like RPX is doing. Waste of SC time.
Like AJ says: Lawyers will run this thing until wheels fall off!!!
