Just reading the docket text that's there, it looks to be a motion brought by the J's, and not a joint motion, though perhaps TPL does not oppose the motion. With an attached exhibit that could be anything from an email complaining that one side or the other is being unfair, or a document showing progression of settlement, or USPTO findings...guess it could be anything, but, unless it's a significant development, whatever it is shouldn't be too much of a surprise to the judge...i don't imagine he'd be pleased.
JMHO.
