Open the CIPO recordAbstract From the Canadian patent
Processes are described for: (1) the sequential solid phase synthesis of polymers with at least one tag, which can be a light emitting and/or absorbing molecular species (optical-label), a paramagnetic or radioactive label or a , tag that permits the physical separation of particles including cells. When multiple optical-labels are suitably arranged in three-dimensional space the , energy transfer from one moleculars species to another can be maximized and the radiationless loss between members of the same molecular species can be minimized; (2) the coupling of these polymers to biologically active and/or biologically compatible molecules through peripheral pendant substituents …

Why it's free to use
- Filed October 7, 2000 and granted August 2, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 7, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 7, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
