Open the CIPO recordAbstract From the Canadian patent
Parenteral emulsion-containing medicament fluid is treated by passing the fluid into a filter assembly. The fluid is introduced via the inlet into chamber and the fluid then passes through a fluid filtration element into chamber and passes out of the filter device via outlet. Passing the fluid through the filtration element blocks microorganisms and other undesirable substances from passing therethrough. Gas which may be present in the fluid and/or the filter assembly may be passed through gas venting elements.

Why it's free to use
- Filed April 28, 1993 and granted January 29, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 28, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 28, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
