Why it's free to use

  • Filed July 29, 1987 and granted September 3, 1990. 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 July 29, 2008.
  • A pharmaceutical extension adds at most five years, so even that would have ended by July 29, 2013.
  • We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
