Is a new invention patentable as a "new invention"?

Ontario, Canada


The following excerpt is from Smith v. Goldie, 1882 CanLII 14 (ON CA):

I am quite willing to accept the doctrine acted upon in Murray v. Clayton, L.R. 7 Chy. 570, and to hold that a new process carried on by known implements or elements, acting upon known substances, and ultimately producing some other known substance, but producing it in a cheaper or more expeditious manner, or of a better or more useful kind, is patentable as a new invention; but the process or the combination must be new.
