Open the CIPO recordAbstract From the Canadian patent
A process for printing images by means of an electrographic or electrostatic device using a toner that is activated by the application of energy. The toner has energy-activated reactive components. An image is formed on a substrate by the toner, without materially activating the reactive components. The reactive components are subsequently activated by applying energy to adhere the image to the substrate by cross-linking and bonding the image permanently to the substrate, or by transferring the image to a second substrate.

Why it's free to use
- Filed February 24, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 24, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 24, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
