Open the CIPO recordAbstract From the Canadian patent
Use of physical vapor deposition methodologies to deposit nanoscale gold on activating support media makes the use of catalytically active gold dramatically easier and opens the door to significant improvements associated with developing, making, and using gold-based catalytic systems. The present , invention therefore, relates to novel features, ingredients and formulations , of gold-based, heterogeneous catalyst systems generally comprising nanoscale gold deposited onto a nanoporous support.

Why it's free to use
- Filed September 23, 2004 and granted October 22, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 23, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 23, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
