An idea has little or no value in the isolation of the conceiver's mind. Artistic creations and developments and improvements in products, machines, and methods are examples of such ideas. Value may be imparted to such an idea by communicating it to others who value it for its utilitarian or esthetic characteristics. Property rights arise from appreciation of such value by others, following communication.
