The Random House Dictionary defines an invention as “a new, useful process, machine, improvement, etc., that did not exist previously and that is recognized as the product of some unique intuition or genius, as distinguished from ordinary mechanical skill or craftsmanship.” Additionally, a patentable invention must not be anticipated by prior art. Examples of prior art include obviousness, where the subject matter would have been obvious to a person having ordinary skill in the art, and prior public knowledge of the inventive step.
