Usually the settlement documents specifically state that if the patent/etc. is declared invalid that they get to keep the money anyway.
So... $45 million is not a bad run for this troll. It will probably encourage them to keep the extortion ring going with another worthless patent.
I see no mention in the newegg blog about the patent being declared invalid, only that newegg was declared not infringing upon it.
While I'm sure this ruling will help anyone else in the future who is simply using SSL on their web server, it doesn't really help anyone else the troll sues who they feel is using SSL/RC4 differently.
They only really need a new worthless patent to go after the same targets they already sued or planned to sue for the same reason.
They get to keep using this same worthless patent still however, just against a different group of targets.
