Minnie creates a new invention called the Bobble Buffer. It polishes jewelry based on programming by the user. No one has ever made this type of machine before, nor have any jewelers thought of this process, but once they see how it operates, they could surely reverse engineer the machine. Minnie learns that you are taking Business Law, so she asks you how she should protect her invention. 1. Should Minnie use a patent or trade secret to protect her invention? Why should she choose one and not the other? 2. Assume Minnie chooses the patent (either based on or against your earlier advice), what are the four requirements Minnie must establish during the application process? 3. Assume Minnie's patent application is approved. For how long will the patent be protected
