Open the CIPO recordAbstract From the Canadian patent
A method for detecting the presence of drug metabolites in the meconium of newborn infants is described. The method involves separation of the drug metabolites from meconium in solution and then assaying the solution for the presence of the drug metabolites. The method is particularly useful for detection of cocaine morphine and, cannabinoids; however, any drug metabolite in the infant meconium can be tested. Conventional assay methods are used for the drug metabolites in the solutions derived from the meconium. The method provides a means for early detection of drug presence in infants which contribute to infant illness.

Why it's free to use
- Filed October 23, 1989 and granted August 11, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 23, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 23, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
