In this video, I get to the bottom of why there is NO requirement that an inventor make a prototype in order to get a patent. While in the old day inventors did need to physically cart their invention over to the U.S.P.T.O, this is no longer the case as everything is filed online. In fact, working prototypes are not even allowed in the present filing process. Instead, the patent office requires an explanation that is detailed enough so that someone of sufficient skill can work from the included information and create your final product. More on this in the video!
