In deciding what is patentable, the Patent and Trademark Office in the US sets criteria that is not necessarily easy to understand, including that the item be new or novel, that it be "useful" and that it be "nonobvious." Philip G. Emma weeds through this criteria in an attempt to make sense of it all and to help inventors decide whether it's worth filing a patent.
