Useful is defined in Section 5.5.2(b).
Useful is defined in Section 5.2.2(b).
Useful means operable, in the sense that the product or process achieves the result that the inventor claims it will. One could not patent a perpetual motion machine, for example, even if its design was highly novel, unless the patent applicant could prove that the machine actually worked (a dubious prospect, at least according to current scientific understanding). At one time patent applicants had to demonstrate some sort of beneficial usefulness for the invention, but that is no longer the case. Even if the invention is so expensive and inefficient that no rational person would ever make or use it, the invention is still eligible for a patent as long as it is capable of performing the function ascribed to it, and meets the other requirements of patentability, such as novelty and nonobviousness.
