Canada-U.S. Patent Prosecution Highway Now Open


January 28, 2008 marked the beginning of a Patent Prosecution Highway ("PPH") one-year pilot project between Canada and the United States. The PPH is a joint initiative between the Canadian Intellectual Property Office ("CIPO") and the United States Patent and Trademark Office ("USPTO") to expedite the examination of patent applications, while also reducing the workload on patent examiners.

That same day, the first-ever PPH (between the U.S. and Japan) became permanent, after a successful pilot project that had been initiated in July 2006. Similar pilot projects are currently underway, including ones between the U.S. and the UK, the U.S. and South Korea, South Korea and Japan, and Japan and the UK.
