Yeah. When Apple claims to have invented something, they don't mean that they invented the very first instance of it, they mean that they invented a practical and transformative consumer implementation, which depending on who you are can be viewed as just as important (because what use is a technology if it can't be used on a practical level?)

I know you meant it in a general sense, but the act of demonstrating something can also be useful. It could be that its not very profitable to manufacture or that it could serve as an inspiration for others to improve upon the idea itself.
