Canadian patent law

From Wikipedia, the free encyclopedia

Canadian patent law is the patent legal regime used to protect inventions within Canada. Patents are in the sole jurisdiction of the federal government and is governed by the federal Patent Act.

A patent will give the inventor and its assignees the exclusive right to the construction, use and sale of the invention.[1]

[edit] Prohibited matters

There are number of matters that cannot be patented. Among such matters include certain new plant matters[2], computer programs,[3] and medical treatments.[4]

[edit] Novelty

The novelty of an invention is determined based on the construction of the claim. The court shall read the claim constructively.[5]

The claim is compared with other inventions to determine whether the invention has already been anticipated.[6] The test is whether a previous claim "contained all of the information which, for practical purposes, is needed to produce the claimed invention without the exercise of any inventive skill". The previous invention must be described in a single document that is generally available to the public.

[edit] Non-obviousness

The test for a non-obvious invention is whether an "unimaginative skilled technician, in light of his general knowledge and the literature and information on the subject available to him on that date, would have been led directly and without difficulty to [the] invention." [7]

[edit] Utility

The requirement for utility originates from the defintion of invention as a "new and useful art"[8] The requirement is generally easy to meet, however, it does limit the scope of protection by excluding methods that would not be useful.
