I think some of the arguments in the video depend much on how tightly invention is defined.<p>Personally, I'd say that even if all components on a circuit board were already individually invented by someone else, as well as the process of combining them, a unique result would likely still be an invention in my eyes.<p>I'd also say that an improvement to an existing product very well could be novel enough to call it an invention (where that line should be drawn is quite subjective though.)<p>Furthermore, I'd argue that piecing together an already existing product through a novel process also could be classified as an invention. For me, it might even be enough to use an existing design in a new way or new field.<p>Thus, I don't think finding one preceding design is a good method in deciding that a later design isn't an invention. Which is not meant to imply that all Apple products are their inventions, just that sometimes the addition of garlic and cilantro (per the video) is novel <i>enough</i>.
