"After yesterdays decision, are the current district court stays now invalid?"

No not at all. The NDCA decision is legal precedent the ITC is not.

I think they were put in place in place due to pendency of the ITC proceedings, I believe it was in May of 2013? I'm asking what officially invalidates the stay? Is another hearing or motion to the court required?

From Ron:

I can't remember why the stay was put in place, but if it was due to the pendency of the ITC proceedings...
