That's often true, but this action is limited to the patents belonging to Newegg and the troll. It won't create legal precedent that other companies can use to slay trolls.
This is correct. They only ask for a judgment that they do not infringe, not that the patent is invalid. They may have done this b/c 1) it's cheaper; 2) they don't want to pay for free-riding by others who will benefit from them taking out this patent; or 3) they want to file for an administrative agency review of the patent's validity, which must be done before you seek such a ruling in court.
