"After reading it again I have different thoughts about Barco. They might be ready to go the distance basedon the fact that they want out of the ADR which is what would facilitate a negotiated settlement. Maybe they don't think they infringe. Any thoughts?"

That would be my take..and essentially that would be any infringers agrument..that would choose to fight against any of the patents that have gone through the gauntlet of the USPTO, courts, or otherwise..i.e. "our products don't infringe on the subject patents"..and they essentially attack TPL's reverse engineering analysis / workproduct..hopefully it is easy to understand and otherwise rock solid..
