 oftentimes we'll see inventors come in and their prototype made somewhere. That prototype outside doesn't indicate that there's the patent pending. It really needs to be shown on the prototype, especially if you're going to show the prototype to others and pending accomplishes the same thing that the patent number does. It puts anybody that sees it on notice that you have a patent on file, that that eliminates that incentive for them to rush and try to protect first. You see that you've already beaten up to that first file step.
