Abstract From the Canadian patent

An electroporation apparatus provides for the electroporation of cells attached to an electrode. The electrode may be transparent to allow cell viewing. If the electrode exhibits a voltage drop a constant electrical field may be obtained over the cell layer by controlling the position or character of the opposed electrode. Alternately cells may be electroporated under an electrical field which varies in a continuous, geometrically uniform manner over the cell layer.

Why it's free to use

  • Filed June 25, 1990 and granted September 4, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 25, 2010.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 25, 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.
