Open the CIPO recordAbstract From the Canadian patent
A soluble ionic complex is formed by an aqueous mixture of a benzylammonium group-containing surfactant and a polynucleic acid sequence. When the mixture forms a vesicular complex, the sequence is packaged therein. This composition is useful in pharmaceutical compositions and in methods of delivering the polynucleic acid sequence (which preferably encodes a protein or peptide) to a cell for expression. Such methods are useful in therapy as vaccines and as , gene therapy agents.

Why it's free to use
- Filed October 28, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 28, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 28, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
