Your list did not mention IMATION? That was one of the ANSWER-COUNTER CLAIMS that caught my eye...

Most of the ANSWERS had to be filed due to Court ORDER denying defendant's Group Motion to have the Markman first, even before they filed their ANSWER...

Of the 19 you list, 3 have been "settled", (Ikagami, Roland, and Wolverine)...

NOKIA, KYOCERA, VTECH, TEAC, ans SAMSON just filed an ANSWER and no COUNTER CLAIMS...These probably are talking to "Settle"...

The rest are still huffing and puffing...I suspect that was the Group that instigated the MOTION to have the MARKMAN HEARING before the ANSWER was filed which was denied by the Court...

Most of the ANSWERS are boiler plate, and some, like IMATION, also threw in the KITCHEN SINK...

Having developed an appreciation of DM'S "Squeeze and settle" strategy at this level, I will not be surprised of more settlements being announced now that the issues are joined, by the time the rest show up in APRIL...
