Patentability

Within the context of a national or multilateral body of law, an invention is patentable if it meets the relevant legal conditions to be granted a patent. By extension, patentability also refers to the substantive conditions that must be met for a patent to be held valid.

== Requirements == The patent laws usually require that, for an invention to be patentable, it must be: Patentable subject matter, i.e., a kind of subject-matter eligible for patent protection (also called "statutory patentable subject-matter") Novel (i.e. at least some aspect of it must be new) Non-obvious (in United States patent law) or involve an inventive step (in European patent law and under the Patent Cooperation Treaty) Useful (in U.S. patent law) or be susceptible of industrial application (in European patent law)
