Abstract From the Canadian patent

Introducing a sample solution that includes a target nucleic acid polymer into a microfluidic device that has a sample region with: (i) a flow channel in fluid communication with one fluid inlet and one fluid outlet; and (ii) a plurality of valves that when closed, partition the flow channel into isolated reaction sites. Each valve is formed from an elastomeric membrane that separates a control channel from the flow channel and which is disposed to be deflected into or retracted out from the flow channel in response to an actuation force to the control channel thereby forming the valve. The method includes closing the valves thereby partitioning the flow channel into isolated reaction sites …

Why it's free to use

  • Filed April 5, 2004 and granted November 18, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 5, 2024.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 5, 2026.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
