Abstract From the Canadian patent

A reaction vessel for a nucleic acid amplification reaction has a first chamber containing an amplification reagent mix a second chamber containing an amplification enzyme, and a fluid channel or chamber connecting the first and second chambers together. A fluid sample is introduced into the first chamber. After a denaturation and primer annealing process has occurred in the first chamber the fluid channel is opened to, allow the solution of the reagent and fluid sample to flow into the second chamber. The second chamber is maintained at an optimal temperature for the amplification reaction. A station is described for processing test strips incorporating the reaction vessels. The station …

Why it's free to use

  • Filed April 7, 1998 and granted June 10, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 7, 2018.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 7, 2020.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
