Open the CIPO recordAbstract From the Canadian patent
Systems and methods for ignition and reignition of unstable electrical discharges wherein a secondary electrode positioned is between a set of primary electrodes and a high voltage is applied between the secondary electrode and successive ones of the primary electrodes to produce pilot discharges that ionize a gas there between and thereby reduce the voltage necessary to ignite a primary discharge between the primary electrodes. Power is provided to the secondary electrode by a circuit which is independent of the circuit that supplies power to the primary electrodes and generates voltage pulses which are substantially higher than the voltage between the primary electrodes.

Why it's free to use
- Filed November 26, 2001 and granted September 25, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 26, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 26, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
