I'm interested in the suggested action though - seems that they only want to stop the defendants' distributing the exploits, which are:

Quote:The Circumvention Devices distributed by Defendants enable users to circumvent or disable the TPMs in the PS3 System:  Hotz’s Metldr Keys, dePKG Firmware Decrypter, 3.55Firmware Jailbreak code and Signing Tool

So even if they totally win the case, the only thing that will occur will be an injunction against them distributing those.  It'll also be easier for Sony to obtain similar injunctions against other parties, but, as it's already out there, this would be difficult.
