Some weeks ago, Spam Arrest won the first patent battle with Mailblocks over Challenge-Response:
“The preliminary injunction must be denied because there are substantial questions as to Mailblocks’ chances of success on the merits (and) because Mailblocks has not demonstrated that it will suffer irreparable injury if the injunction is denied,” according to the filing.
Spam Arrest deserves to die, but so do the Mailblocks patents.
