The present invention provides compositions comprising at least one oligomeric compound comprising an alternating motif and further include a region that is complementary to a nucleic acid target. The compositions are useful for targeting selected nucleic acid molecules and modulating the expression of one or more genes. In preferred embodiments the compositions of the present invention hybridize to a portion of a target RNA resulting in loss of normal function of the target RNA. The present invention also provides methods for modulating gene expression.

Why it's free to use
- Filed November 4, 2003 and granted July 22, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 4, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 4, 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.
