Open the CIPO recordAbstract From the Canadian patent
A tunable blade structure for use in a communication plug terminating a cable carrying a plurality of conductors. One end of the blades is designed as an insulation displacement connector (IDC) for electrical communication with the conductors from the cable. The other end of the blades is designed as a jack contact region for electrical communication with jack springs. Between these twoends are three regions for manipulating the electrical characteristics of the blades: a capacitive coupling region, an inductive coupling region and an isolation region. By appropriately designing these three regions electrical interference (i.e. crosstalk) between the conductors can be optimized.

Why it's free to use
- Filed August 10, 1998 and granted October 1, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 10, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 10, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
