I've wondered the same thing. I haven't seen any activity on the USPTO website in months. They jumped on the '584 EDOT bandwagon quickly and then it seems everything went silent. I can't help but wonder if it does have some correlation with the '336 and '148 re-exams. As I've said several times, the USPTO was quick to side with the court on the '584 but much less receptive to the courts opinions on the '336/'148 or least that was my interpretation.
