Thank you khenry. It would seem they are still moving forward with the Daubert hearing. This looks like a Daubert brief, as it doesn't mention the new theory introduced. Perhaps they will leave it to the judge to decide the fate of the deposition and new theory separately at the end of the month.
I thought there were only six patents in question. That's all I found on the PTAB when I bought in a couple of years ago. Anyhow, I didn't read the entire brief, but it's interesting that they only seem to be disputing parts of 3 of the patents. What are we to think about this? They are resigned to paying, but they are just trying to minimize the damage?
