Why it's free to use

  • Filed November 23, 1999 and granted March 6, 2003. 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 November 23, 2020.
  • A pharmaceutical extension adds at most five years, so even that would have ended by November 23, 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.
