Why it's free to use
- Filed October 27, 1983 and granted August 5, 1987. 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 October 27, 2004.
- A pharmaceutical extension adds at most five years, so even that would have ended by October 27, 2009.
- We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
