Why it's free to use
- Filed April 27, 1993 and granted June 4, 1996. 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 April 27, 2014.
- A pharmaceutical extension adds at most five years, so even that would have ended by April 27, 2019.
- We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
