Open the CIPO recordAbstract From the Canadian patent
Methods for isolating a compound from a multipart typically biological sample. The methods use at least one paramagnetic particle having an associated electronic charge to bind compounds with the opposite charge to form a particle/compound complex. Alternatively the paramagnetic particles have a ligand or functional group with an affinity for a target compound to form a particle/compound complex. The complex can be immobilized by applying a magnetic field to the particle/protein complex. The sample may be further processed to obtain a protein sample in a more pure form or a sample depleted of select compounds.

Why it's free to use
- Filed August 1, 2005 and granted April 3, 2018. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 1, 2025.
- Certificates of supplementary protection extend only drug patents, and it isn't classified as one.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
