Especially when it is meshed into the story. HTC knows they infringe so you start a bi lateral front on validity via ex-parte re-exams in the PTO and FDOC action knowing it will be delayed pending the pto exam. If you lose in the PTO you still argue validity in the FDOC and if that unravels you argue infringement while arguing if you do infringe the license amounts are minimal because of the last five year of instability we have put you in. Brilliant!! Those lawyers should make millions for being that snakey. Oh but they have!!
