My co-blogger Nate wrote yesterday about Magistrate Judge Hall's discussion of prior art estoppel in Innovative Memory Systems Inc. v. Micron Technology Inc., No. 14-1480-RGA (D. Del.

I don't have the full transcript, but based on quotes set out in a letter filed by the parties, Judge Connolly recently set forth his thoughts on the kinds of issues he is willing to address early in the case:

Now, what I try to do when I think there's kind of a silver bullet, I move it to the top of the pile. That's what I do on indefiniteness.
