D'après Wikipedia :

The patent laws usually require that, in order for an invention to be patentable, it must

* be of patentable subject matter, ie a kind of subject-matter that is eligible for patent protection,
* be novel (i.e. at least some aspect of it must be new),
* be non-obvious (in United States patent law) or involve an inventive step (in European patent law); and * be useful (in U.S. patent law) or be susceptible of industrial application (in European patent law).

En pratique on est loin, hélas.
