Open the CIPO recordAbstract From the Canadian patent
A quantitative measurement system includes an external unit (101a) and an internal unit (102a) are provided for obtaining quantitative analyte measurements, such as within the body. In one example of an application of the system, the internal unit (102a) would be implanted either subcutaneously or otherwise within the body of a subject. The internal unit (102a) contains optoelectronics circuitry (102b), a component of which may be comprised of a fluorescence sensing device. The optoelectronics circuitry (102b) obtains quantitative measurement information and modifies a load (102c) as a function of the obtained information. The load (102c) in turn varies the amount of current …

Why it's free to use
- Filed June 27, 2001 and granted April 5, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 27, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 27, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
