Dude - if it isn't obvious by now...
There will be no fat lady singing at any stage.
Neither the courts, the defendants or our licencing team have any interest in seeing a conclusion to this. No-one benefits from a final resolution except Joe-Shmoe Stockholder, i.e. no-one that actually matters.
There are too many lawyers making too much money to want this to stop. There will be appeal after reexamination after claim reconstruction after juristictional precidence after injunction after sopoena - this is what lawyers do - this is how they make their money. They will not stop because they don't have to, and they don't want to.
The patents themselves will expire eventually, and/or the plaintiffs (us) will run out of money. Once this happens and the carcass has been picked clean, there will be much sadness and recrimination at the wonderful opportunity lost. Oh well, never mind, carry on...
In the meantime, everyone involved can get busy planning their long and happy retirements - all except Joe Shmoe, who is currently too busy paying for it.
