Open the CIPO recordAbstract From the Canadian patent
The invention relates to a nuclear magnetic resonance method of detecting and monitoring the flocculation kinetics of high molecular weight fractions of a complex fluid. The inventive method consists in applying the following to the fluid: a first static polarisation magnetic field and subsequently, at least a second oscillating pulsed magnetic field which is intended to generate a nuclear magnetic resonance for the nuclei considered and the acquisition of relaxation signals from the nuclei in the fluid. Moreover said method consists in: detecting, in the relaxation signals a first part P1 which is representative of the relaxation of said flocculated fractions in the fluid and a second part …

Why it's free to use
- Filed January 16, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 16, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 16, 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.
