Why it's free to use

  • Filed June 21, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 21, 2020.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 21, 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.
