Open the CIPO recordAbstract From the Canadian patent
Methods, compositions and articles of manufacture involving cationic conjugated conformationally flexible polymers are provided. A method for the synthesis of cationic water-soluble polymers with linkages along the polymer main chain structure which disrupt the ability of the polymers to form extended-rod structures is provided. Such polymers may serve in the fabrication of novel optoelectronic devices and in the development of highly efficient biosensors. The invention further relates to the application of these polymers in assay methods.

Why it's free to use
- Filed September 17, 2004 and granted April 14, 2015. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 17, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 17, 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.
