Open the CIPO recordAbstract From the Canadian patent
An intermediate transfer member defines a transfer nip with a transfuse member. A cooling platen contacts the intermediate transfer member in the post-transfer nip region. The cooling platen absorbs heat from the intermediate transfer member to evaporate a liquid into a gas. The gas is directed to a heating platen contacting the pre-nip region of the intermediate transfer member. The heating platen condenses the gas to a liquid to heat the intermediate transfer member.

Why it's free to use
- Filed December 7, 2000 and granted March 11, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 7, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 7, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
