Open the CIPO recordAbstract From the Canadian patent
Compositions and methods for determining the presence or concentration of glucose in a sample which may also contain an alpha-hydroxy acid or a betadiketone. The method uses a compound having at least two recognition elements for glucose, oriented such that the interaction between the compound and glucose is more stable than the interaction between the compound and the alphahydroxy acid or beta-diketone, such that the presence of the alpha-hydroxy acid or the beta-diketone does not substantially interfere with said determination.

Why it's free to use
- Filed January 4, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 4, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 4, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
