Why it's free to use

• Filed January 14, 1986 and granted July 28, 1989. 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 January 14, 2007.
• A pharmaceutical extension adds at most five years, so even that would have ended by January 14, 2012.
• We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
