Open the CIPO recordAbstract From the Canadian patent
The use of non-viral delivery of therapeutically effective compositions through aerosol for therapy or research purpose has been limited by the low efficiency mainly caused by an inefficient delivery system and destruction of formulation (gene and/or delivery sytem) by aerosol shearing power. This invention develops formulations that are established polymer combination formulations. The formulations are highly efficient in delivering genes in vivo through aerosol and are able to protect the delivered gene from the destruction by aerosol shearing power.

Why it's free to use
- Filed February 1, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 1, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 1, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
