Opps sorry about the prior blank post.

Toshiba and NEC separately requested patent review. Based on that, one would expect that the primary defense is prior art/obviousness.  Are we now saying prior art/obiousness is no longer part of the J2 defense?  I read through the defenses and did not see it, but not sure if I would recognize it. Can anyone with expertise in legaleze and familiar with all the filings please confirm that this is indeed the case. Many thanks in advance. opty
