new and useful inventio - Bouvier's Law Dictionary, Revised 6th Ed (1856) :

  NEW AND USEFUL INVENTION. This phrase is used in the act of congress 
  relating to granting patents for inventions. 
       2. The invention to be patented must not only be new, but useful; that 
  is, useful in contradistinction to frivolous or mischievous inventions. It 
  is not meant that the invention should in all cases be superior to the modes 
  now in use for the same purposes. 1 Mason's C. C. R. 182; 1 Mason's C. C. R.
