Why it's free to use
- Filed June 10, 1994 and granted August 13, 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 June 10, 2015.
- A pharmaceutical extension adds at most five years, so even that would have ended by June 10, 2020.
- We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
