Obviousness

The Patent Act stipulates that the subject matter defined by a claim in an application for a patent in Canada must be subject matter that would not have been obvious on the claim date to a person skilled in the art or science to which it pertains. The word “invention” implies ingenuity, without which an advance is obvious; and patents are not granted for the obvious.
