Open the CIPO recordAbstract From the Canadian patent
The invention is an electrochemical capacitor with its electrodes made on a conducting substrate with a layer of a redox polymer of the poly-Me(R-Salen) type deposited onto the substrate. Me is a transition metal (for example Ni, Pd, Co, Cu, Fe), R is an electron-donating substituent (for example CH30-, C2H50-, HO-, -CH3), Salen is a residue of bis(salicylaldehyde)-ethylendiamine in Schiff's base. The electrolyte comprises of an organic solvent compounds , capable of dissolving in such solvents with the resulting concentration of no less than 0.01 mol/1 and dissociating with the formation of ions which are , electrochemically inactive within the range of potentials from -3.0 V to +1.5 …

Why it's free to use
- Filed October 3, 2003 and granted May 6, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 3, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 3, 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.
