My Patent DE 19926640 is so attractive that is has been copied from the Patent_troll www.safenet-inc.com: http://www.google.com/patents?id=JwsSAAAAEBAJ&printsec=abstract&zoom=4&dq=safenet+random&ie=ISO-8859-1
Because this patent a simple patent piracy and not valid due to prior art, i wrote to the United States Patent and Trademark Office, but they only want my best (money: $2520 for a Request for ex parte reexamination or $8800 for a Request for inter partes reexamination).
So if you have a problem with the US patent 6807553 i can certity for free that everything in it has been implemented and used more than five years ago and that it is invalid due to Prior art. If you have to pay for or other problem with the US patent 680755, please contact me; if necessary i will my contact my Patent Lawyer or the WIPO.
