Open the CIPO recordAbstract From the Canadian patent
A diagnostic kit for measuring a characteristic of a fluid sample includes a test strip (e.g. a disposable blood glucose test strip) and device (e.g. a hand- held meter) for measuring a property (e.g. an optical or electrochemical property) of the test strip. The device also calculates based on the measured property of the test strip a characteristic (e.g. blood glucose concentration or INR) of a fluid sample applied to the test strip. Stored in a memory of the device are test strip calibration codes that represent geometric regions (e.g. polygonal or hexagonal geometric regions) of a multi- dimensional calibration parameter space. The test strip calibration codes and geometric regions are …

Why it's free to use
- Filed August 20, 2003 and granted July 19, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 20, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 20, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
