CANADA
prior art that is disclosed within one year of an application’s eff ective date will not be citable against an invention in the US. A patent’s eff ective date can either be the application’s fi ling date or the priority date. In Canada, however, the grace period requires a Canadian patent application to have a fi ling date within one year of an inventor’s disclosure.
THE SIGNIFICANTLY REDUCED COSTS OF EXPEDITED EXAMINATION MAKE FILING AND
EXPEDITING PROSECUTION IN CANADA A MORE ATTRACTIVE ECONOMIC OPTION IN COMPARISON TO THE US.
Canada does not allow the submission of post-filing data to support predictions about a claim’s utility or soundness. By contrast, the AIA allows the submission of post-filing data. Applicants must therefore include sufficient data at the time of filing, within one year of an initial priority filing, or within one year of an initial public disclosure, when filing for patent protection in Canada.
There are no terminal disclaimers to manoeuvre around double patenting in Canada. If a double-patenting objection cannot be overcome by argument, the claims will need to be amended to eliminate the overlap that is cited by the examiner. Accordingly, we advise that the full breadth of the invention should be claimed in a single application, particularly in view of no associated fees for excess claims. Alternatively, if the applicant believes that it has claims that should be filed as a divisional application, we would recommend adding the new claims to the parent application to trigger a unity of invention objection from the examiner, thus avoiding a double-patenting objection down the road.
Unlike in the US, there is no absolute ‘on-sale bar’ in Canada. It is possible for an invention to be sold, but due to the nature of the invention (if the product that is sold cannot be reverse-engineered to reveal the subject matter of the invention), the sale is not considered to be a disclosure. Therefore, patent applications that would be prohibited in the US may still be able to be granted as patents in Canada.
Preventing counterfeiting with IP
Industrial design, trademark and copyright protection are not mutually exclusive, which could be used to an IP owner’s advantage when doing business in Canada.
