useful

Serviceable. Beneficial. The word "usefulness" implies capabilities for use, and appertains to the future as well as the present. Chesapeake, Ohio & Southwestern Railroad Co. v Dyer County, 87 Tenn 812, 11 SW 943. An invention is useful, as the word is used in the patent laws, if it is capable of being beneficially used for the purpose for which it was designated. Or, as sometimes stated, if it will operate to perform the functions and secure the results intended, and its use is not contrary to law, moral principles, or public policy. A device which may be used for innocent amusement may possess utility. See Callison v Dean (CAIO Okla) 70 F2d 55.
