the Lovenox patent case is considered urgent by nobody
Ok, not following - since the ASM reportage by the Rocky makes it clear that Momenta is(!) worried about the delay (due to the possibility of a bunch of other market entries being approved in the relatively near term) and didn't like the delay. Similarly one has to assume that Teva too had little say.
Thus the trial date was a decision made by only 1 person, different from the people previously assumed as the decision drivers on whom so much board weight was placed at the original announcement about the late date and who probably has only a little data we don't have and has much less industry/technical knowledge.
