Open the CIPO recordAbstract From the Canadian patent
An insulator ring for preventing short circuit contact between the opposite polarity electrode in a case-terminal cell design is described. Typically a, lithium/silver vanadium oxide cell is built in a casenegative design with the casing serving at the negative terminal. The cathode is connected to an insulated terminal pin. In a conventional cell construction the, electrode assembly is enclosed in an insulator bag in addition to the electrode separator envelopes before being housed inside the casing. The insulator bag ensures the cathode electrode will not come into short circuit contact with the casing. In the present invention, the insulator bag is replaced with an insulator ring which …

Why it's free to use
- Filed July 19, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 19, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 19, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
