On January 28, 2008, the Canadian Intellectual Property Office (CIPO) launched a one-year pilot program to help fast-track patent examination in Canada and the U.S. The Canada-U.S. Patent Prosecution Highway (PPH) is currently being used by the United States Patent and Trademark Office (USPTO), the Japan Patent Office, the United Kingdom Intellectual Property Office and the Korean Intellectual Property Office. PPH seeks to permit patent offices in participating countries to benefit from each other's work. For example, if claims of an application have been found to be allowable in a participating country, accelerated examination of those claims may be requested in another participating country.
The pilot program will end on January 28, 2009, but may be extended for up to an additional year, if necessary, to adequately assess its feasibility.
