Open the CIPO recordAbstract From the Canadian patent
Lentiviral vectors modified at the 5' LTR or both the 5' and 3' LTR are useful in the production of recombinant lentivirus vectors (See the Figure). Such vectors can be produced in the absence of a functional tat gene. Multiple transformation of the host cell with the vector carrying the transgene enhances virus production. The vectors can contain inducible or conditional promoters.

Why it's free to use
- Filed April 26, 2000 and granted August 2, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 26, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 26, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
