Abstract From the Canadian patent

The present invention relates to methods of monitoring the menstrual cycle and/or the first half of pregnancy in a female by assessing the adhesion of lymphocytes from the female to uterine or lymphoid histological tissues from a pregnant animal or an animal that has been treated with gestational hormones. The method can be used to determine the ability of the lymphocyte donor's immune system to recognize and respond to an environment suitable for sustaining a pregnancy.

Why it's free to use

  • Filed October 27, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 27, 2023.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 27, 2025.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
