Why it's free to use

  • Filed June 10, 1999 and granted February 12, 2004. An Australian standard patent lasts 20 years from its date of patent, which is at most a year after this filing, so its term ended by June 10, 2020.
  • A pharmaceutical extension adds at most five years, so even that would have ended by June 10, 2025.
  • We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
