"Apart from any stay, if the patent survives the IPR, there is a significant chance the IPR estoppel provision could preclude a litigant from challenging validity at trial based on prior art that could have been raised in the IPR. If the litigation is stayed, this outcome is nearly certain. Also, the AIA gives a patent owner the right to stay litigation once an IPR is instituted, unless the district court judge determines a stay would not be in the best interests of justice".

Till now there is no indication by judge re stay of the case. JMO
