Open the CIPO recordAbstract From the Canadian patent
An electrostatic discharge protection device that fits within a connector for high frequency cables having a tubular ground conductor surrounding one or more core conductors. The electrostatic discharge protection device creates a shunt across the one or more core conductors and the ground conductor thus electrically grounding any electrostatic discharge on the one or more core conductors. Upon joining of a complementary receptor to the connector the electrostatic discharge protection device automatically withdraws the shunt reestablishing electrical isolation among the one or more core conductors and the ground conductor.

Why it's free to use
- Filed April 26, 1995 and granted October 30, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 26, 2015.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 26, 2017.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
