Why it's free to use
- Filed October 16, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 16, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 16, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
