Open the CIPO recordAbstract From the Canadian patent
Physical changes resulting from an association between a template molecule and a target molecule are detected by monitoring changes in the template molecule. Exemplary changes include a change in a physical dimension or stiffness of the template molecule, a change in electrical conductivity of the template molecule and a change in the energy required to dissociate the target molecule and the template molecule. The magnitude of the change is indicative of the specific identity of the target molecule.

Why it's free to use
- Filed August 6, 2004 and granted July 11, 2017. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 6, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 6, 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.
