Why it's free to use

  • Filed May 14, 1997 and granted February 8, 2001. 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 May 14, 2018.
  • A pharmaceutical extension adds at most five years, so even that would have ended by May 14, 2023.
  • We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
