Abstract From the Canadian patent

A method for acquiring nuclear magnetic resonance measurements of a material uses a gradient tool. A modified CPMG sequence is used wherein the duration of the refocusing pulse is selected to maximize the SNR of the pulse echoes relative to a standard CPMG sequence in which the refocusing pulse has twice the duration of the tipping pulse.

Why it's free to use

  • Filed September 28, 2001 and granted August 7, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 28, 2021.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 28, 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.
