Open the CIPO recordAbstract From the Canadian patent
An alloy having a low reactivity towards certain high temperature superconducting materials at temperatures up to about 10°C lower than the melting point of the alloy. The alloy is a ternary silver-based alloy consisting by weight, of, 0.5-9% palladium, 20-40% gold balance silver. Using the alloy and a, superconducting material of the type R-Ba-Cu-O where R is yttrium or a rare earth, element composite conductors can be formed at temperatures equal or higher thanthe temperature of peritectic decomposition of the superconductor. The alloy mayalso be used as a buffer layer or cladding material on substrates having unacceptably high reactivity towards the superconducting material.

Why it's free to use
- Filed November 23, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 23, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 23, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
