It's a simple matter of judicial protocol. These are renewed JMOL motions that GOOG filed post-verdict that were continuing the same line of argument that they started during their PRE-trial JMOL motions.
And once these motions were filed -- which we all knew about back on 12/18 -- the subsequent opposition briefs and reply briefs were expected by everyone, especially after JJ ordered 850 in granting 846, and established 2/15 as the hard deadline for filing these reply briefs.
Again, nothing out of left field here. Not sure who you're relying on for your info, but you may want to take a step back and re-assess things. As much as it may seem that I am giving you a hard time, I assure you my intentions are good -- after all, after this case wraps up, I would hate for you to have to change your handle to "ive been had again"...
