Once an invention is patented in Canada, exclusive rights are granted to the patent holder as defined by s.42 of the Patent Act (R.S.C., 1985, c. P-4).[1] Any interference with the patent holder's "full enjoyment of the monopoly granted by the patent" is considered a patent infringement.[2] Making, constructing, using, or selling a patented invention without the patent holder's permission can constitute infringement.[1]Possession of a patented object,[3] use of a patented object in a process,[4] and inducement or procurement of an infringement[5] may also, in some cases, count as infringement.
