Open the CIPO recordAbstract From the Canadian patent
Method and compositions are provided for the determination of telomere length and telomerase activity as well as the, ability to inhibit telomerase activity in the treatment of proliferative diseases. Particularly primers are elongated under conditions which minimize interference from other genomic sequences so as to obtain accurate determinations of telomeric length or telomerase activity. In addition, compositions are provided for intracellular inhibition of telomerase activity and means are shown for slowing the loss of telomeric repeats in aging cells.

Why it's free to use
- Filed May 13, 1993 and granted June 26, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 13, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 13, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
