Open the CIPO recordAbstract From the Canadian patent
In this process a conductive first layer composed of finely divided metal and finely divided ceramic material in an organic carrier is applied to a surface of an unsintered ceramic body. The conductive layer forms terminations when the body and, the conductive layer are cofired to sinter and form a unitary integral, monolithic structure. A second conductive metal layer may be applied to the first layer prior to cofiring to improve attachment capabilities of the component. Leads may be attached to the conductive terminations if desired.

Why it's free to use
- Filed April 19, 1990 and granted March 8, 1994. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 19, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 19, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
