IF there is no technical difference between the digital transmission of a video/sound file and any other file, their patent is useless anyway and you don't need to find prior art.
Examples:
A CD player.
there's no technical difference between different CDs. you can play any music CD on it. NOBODY can come and say "but I have the patent on playing heavy metal mudic CDs".
physical transportation. (let's say with UPS)
there's no difference between transporting a DVD and a document. NOBODY can come and say "I have a patent on transporting DVDs from one place to another".
If you'd need a special tool or technology to transport a DVD, ok.
But that's not the case.
And as I already said: If there's no technical difference between the digital transmission of video/audio files and any other files, then their patent is invalid.
Where's the proof from ACACIA. What's their technology? That's what I'd like to know.
