Open the CIPO recordAbstract From the Canadian patent
An EMI feedthrough filter terminal assembly includes a feedthrough filter capacitor (300) having first (306) and second (308) sets of electrode plates a passageway having a first termination (324) surface conductively coupling the first set of electrode plates, and a second termination surface exteriorly coupling the second set of electrode plates. A conductive ferrule (318) disposed adjacent to the capacitor includes a conductive pad of an oxide resistant biostable material on a surface thereof conductively coupled to the second termination surface. A conductive terminal pin (416) extends through the passageway in conductive relation with the first set of electrode plates and …

Why it's free to use
- Filed February 27, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 27, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 27, 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.
