fNo your wrong!! I no exactly how patents work. I am in one now that has an European patent and a U.S. pending. It cost you very little to apply for the patent an while it is pending. when it is apjprove tht is when you pay the big money. This machine was suppose to have already had a patent on it and the after the fact items is what kept the Microfill from being at the minn pack convention because they were FILING FOR MORE PATENTS!!!!! Which never happened. Has anybody called the TA lately?????
