Why it's free to use

  • Filed August 27, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 27, 2012.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 27, 2014.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
