In Canadian patent law, only “inventions” are patentable. Under the Patent Act,^[1] only certain categories of things may be considered and defined as inventions. Therefore, if a patent discloses an item that fulfills the requirements of novelty, non-obviousness and utility, it may nonetheless be found invalid on the grounds that it does not fall within one of the statutory categories of “invention”. Since the Patent Act, the categories of patentable subject matter have been defined and interpreted by Canadian courts.
