We've been through the patent thing many times. Lol!
For starters it's quite easy to go to the patent database and just how many, or how few are directly assigned to MCET. Then you can look up the foreign ones and that they mostly have lapsed or were abandoned. Oh never mind, it's not possible for a rational person to believe that junk. Quietly working? LMAO! They can't or won't even pay the phone bill.
