Open the CIPO recordAbstract From the Canadian patent
Plate and electrode assemblies include configurations allowing for relatively uniform electric field production. The electrodes may comprise strips of conductive material plated onto the bottom surface of sample wells or they may comprise plate electrodes extending down into the well. In some embodiments the electric field strength varies by less than about 10% from a mean field intensity over at least about 20% of the surface area of the bottom surface of a sample well.

Why it's free to use
- Filed July 9, 2001 and granted June 18, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 9, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 9, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
