A great design idea, but, the materials to make it, work were not developed until about 50 years after the patent expired. Nikola Tesla patented computer logic also. Guess who was so very surprised and disapointed decades later, when computer technology became practical. A Wizard dosn't want to be slowed down by the patent process. He understands the role and need for patents in the commercialization of devices, but has seen the best ideas and devices get lost because of patent issues.
Wizards work in the present.
They attend to the needs of the moment. If you want a patent you can't use or publicly demonstrate your idea until the patent is processed. You could wind up spending tens of thousands of dollars trying to patent an idea, only to have someone else get it. After you get the patent you then have to sell it or find money to develop it. By the time you get it all together, your patent has expired and anyone can use the idea without giving you anything.
