Here's another company seeking to sue Sony called Certicom ! This is proof that there is a movement to stop Sony, PS3 and Blu-ray ................
This time it’s a company called Certicom Corp. and it's not just about the PS3 but almost every electronic device Sony has made over the years. Certicom believes Sony has broken two U.S. patents for digital content protection by using Certicom digital encryption technology. This patent is affecting everything from the PS3 all the way to personal computers Sony has been making for years now.
