This would be one or more utility patents for the strongest protection. You can protect the interface arrangement, sequence of menus, or whatever it is that gives it the most value. Copyrights can be used in addition, and can be useful against pirates, but do not provide much protection against someone who reverse engineers the design. Copyrights should be registered before infringement occurs for maximum value.
