Why it's free to use
- Filed December 12, 1996 and granted April 20, 2000. 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 December 12, 2017.
- A pharmaceutical extension adds at most five years, so even that would have ended by December 12, 2022.
- We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
