Open the CIPO recordAbstract From the Canadian patent
An electrochemical mirror includes a transparent first electrode (106) and a second electrode (110) distributed in localized areas. An electrolytic solution (112) is disposed between the first and second electrodes and contains ions (116) of a metal which can electrodeposit on the first and second electrodes. A negative electrical potential (118) applied to the first electrode causes deposited metal to be dissolved from the second electrode into the electrolytic solution and to be electrodeposited from the solution onto the first electrode, thereby affecting the propagation of electromagnetic radiation through the mirror. A surface modification layer (108) applied to the first …

Why it's free to use
- Filed December 15, 1998 and granted September 2, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 15, 2018.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
