Patenting Great Ideas

My father is one of the smartest people that I have ever known. He is always coming up with ideas to help my mother out around the house. He makes different gadgets all the time, and she says that they really do help her out a lot. Other than that, he has never really done anything with his great talent. The last gadget that he made was great and I even had him make one for me. I liked it so much, that I finally convinced him to fill out a patent application for it. He is selling them like crazy, so I am glad that I convinced him.
